A two-day school on 'Recent Developments in In-PulpTechnology' was held on 7th and 8th October, 1991, atMintek. A number of interesting developments relating toin-pulp technology have taken place since the last SAIMMschool on activated carbon was held. These includecontinuous elution, high-concentration adsorptioncontactors, and the development of resin technology forgold adsorption. The objectives of the school were tothoroughly review the basic principles of in-pulp plant

design and operation, as well as to highlight important newdevelopments in the area. A total of seventy delegatesattended the school.

A colloquium on industrial minerals entitled' A Strategyfor Growth in the Industrial Minerals Sector' was held atMintek on 5th November, 1991. A total of eighty-sixregistered, a predominance of the delegates being non-members of the SAIMM. Two overseas delegates wereregistered. A total of twelve papers were read, one ofwhich was presented by an overseas author, Ms AlisonRussell, deputy editor of Industrial Minerals, whoprovided a resume of the total outlook for industrialminerals in South Africa.

A three-day school on 'Mineralogy for MineralsProcessing' was held on 19th, 20th, and 21st May, 1992, atMintek. The aim was to provide the metallurgist with abetter appreciation of the mineralogical methods availablefor identifying the components of mineral assemblages.The School covered such familiar topics as XRD and XRF,and introduced more modem techniques such as imageanalysis coupled to scanning electron and opticalmicroscopes. Case studies of the effects of mineralassemblages on the design and operation of existingtreatment operations were presented, including Barbertongold, platinum-group mineralogy, and base-metalmineralogy (Cu, Pb, Zn, Sb). Beach-sand heavy mineralsand ferrous minerals were also discussed.

A colloquium on 'Environmental Issues and Recycling'was held on 14th July, 1992. The theme was the businessadvantages obtainable from the recycling of waste products.

This was a year of consolidation during which attentionwas given to the implementation of strategy and theallocation of portfolios for its extension. In doing so, it isrecognized that the Committee for the Environment is a co-ordinating committee that will carry out its mandatethrough the existing structures of Council and itscommittees, avoiding any duplication of their initiatives.This approach emphasizes that the responsibility for theenvironment is not divorced from the normal activities ofCouncil, nor from members of this Institute but indeed is anintegral part of them.

In this way, environmental awareness, literacy, andresponsibility are being promoted through the technicalprogrammes in mining, extractive metallurgy and metalstechnology, career guidance and education, awards, theInstitute's Journal. and the branch activities.

In this vein, and at the time of writing, arrangements havebeen made to hold a colloquium in July on environmentalissues, with particular reference to recycling. Plans are alsobeing made to hold a school in the new Council year onintegrated environmental management (IEM), coupled withcolloquia that will probably take the form of case studies.

The Institute again supported the EPPIC NationalPremium Award by inviting submissions from its corporateand individual members. Duvha Opencast Services andBlack Mountain Mineral Development Company wereassessed according to EPPIC's main criteria, which requireevidence of the successful application of the principles ofIEM from conception of a project to a stage when it issufficiently mature to show the effectiveness ofenvironmental-management plans and their execution.Unfortunately, Council's nomination of Duvha OpencastServices was not successful. (See also Section 5.12.)

At the request of EPPIC's constituent institutes, Councilconsidered and adopted the principles for environmental

management contained in the business charter forsustainable development of the International Chamber ofCommerce, copies of which are obtainable from the SouthAfrican Council of the ICC, P.O. Box 91267, AucklandPark, 2006.

2.6 Special Interest Group-Surface Mining

W J. Abel, Chairman

Unfortunately, owing to the disbanding of the previouscommittee and the difficulty in appointing a new committee,no events were organized during the year.

However, sufficient interest continues to be shown in thisGroup, and proposals for the revitalization of the Grouphave been tabled.

2.7 Special Interest Group-Computer Applications

P. van Schaardenburgh, Chairman

The SIGCA Committee was restructured, and the processof acknowledgement and communication between the data-processing and the mining-production disciplinesprogressed positively. The objective of a combinedprogramme with the universities and technikons was notmet, probably because of diverse interests.

The SIGCA will therefore remain active in the areas ofone- or half-day seminars, as before. The recently heldseminar on computer-based mine planning is a typicalexample of the Group's activities.

A seminar entitled 'Computer Mine Planning-Is ItWorth It?' was held on 10th June, 1992, at the BmamfonteinHotel. The seminar was attended by 113 delegates.

2.8 Speciallmerest Group--Process Control

Dr MH. Moys, Chairman

The Group paid two visits this year, and one more isplanned. Attendance was generally good, indicating that theGroup is fulfilling a need in the industry. It is worthemphasizing here that visits are open to all SAIMMmembers and their guests-not just the members of theInterest Group.

The visits to Western Deep Levels focused on thecomputer systems available for the control of the grindingmills and the elusion circuit, and was highly valuedby attendees.

The visits to Kenwalt (consultants in process optimizationand control) heralded a change from the plant visits that hadtypified the activities of this Group. Delegates were treatedto demonstrations and case studies of steady-state anddynamic simulation, and its use in the design of process,process control, and operator training systems.

The next in the series of visits to consultants in theprocess-control field will be a visit to Azon Controls(formerly APe) on 2nd September, 1992. The 1993programme will explore what is to be learnt from thechemical industry.

The Journal Committee and Programme Advisory Boarddevoted time during the year to reviewing the appearanceand content of the Journal and the interests of its readership.A new typeface was selected, a less expensive paperintroduced, and certain cosmetic layout changes effected.

Supply of both commissioned and submitted papers wasadequate. The delay between receipt and publication is atpresent excessive. This arises from the referee system andthe time taken by authors to prepare final copy. Thesupply of the appropriate referees is necessarily limited,and it is inevitable that some of them carry heavyworkloads. The Committee is grateful to those refereeswho have been prepared to undertake this task withoutreward or public acknowledgement.

While the DTP staff have moved rapidly up the learningcurve, and are working both well and timeously, productiondelays at the printer have delayed the appearance of theJournal. Regrettably, no issue of the Journal has appearedthis year in the month of issue.

The Council has given attention to proposals for furtherchanges that are aimed at a reduction of these problems. Inparticular, the Journal Committee is concerned to increasethe readability of papers and to make the Journal moreattractive to members. This would also attract much-neededadditional advertising.

The branches of the Institute had another active year. Thebranch chairmen and their committees must becongratulated on their efforts to arrange stimulatingtechnical/commercial meetings and excursions for themembers of their branches.

The name of the Witbank/Middelburg Branch has beenchanged to the Eastern Transvaal Branch, and now includesthe Standerton area.

The Vaal Triangle Branch was without a committee forsome time. Mr Tony de Sousa was appointed actingChainnan and, through his enthusiasm and leadership, heand his ad hoc Committee managed to revive the Branchand the interest of members by an innovative idea. Breakfastmeetings are being held regularly at which prominentspeakers deliver talks on very topical subjects (non-technical). These proved very successful. In addition, thetechnical evenings and plant excursions were well attended.

The Regional Development Committee re-established theboundaries of the branches. Minor recommendations weremade and accepted. For example, the Western Cape Branchwill include the eastern Province, but not the northwesternCape. (A new branch or chapter could be initiated for thisarea, which could also include Kimberley.) The VaalTriangle Branch includes Sasolburg and the coal mines ofthe northeastern Orange Free State. New branches are stillto be established in the northern Transvaal, Natal,and Zululand.

Discussions were held with the Association of MineManagers of South Africa, as well as with other professionalmines associations, and these will continue. Interaction withother bodies active in the mining and metallurgicalindustries will also continue.

The Johannesburg Branch once again completed a mostsuccessful year. The efforts of the Committee and thesupport of local Institute members are the main ingredientsthat contributed to this success. After much debate, theCommittee decided it was the tried and tested combinationof regular general meetings, where topics of interest arepresented by respected speakers, and one-day technical

visits to mines, metallurgical plants, and other facilities thathas been, and remains, a successful fonnula and one thatshould therefore not be tampered with. The regular venueof the general meetings at the Johannesburg Country Clubhas proved extremely popular because of the Club'sproximity to the central business district of Johannesburg,its good facilities, and ample parking. The large turnout atgeneral meetings owes much to these factors. Every effortwill therefore be made to procure the use of this venuein future.

The Committee is made up of members from the sixmajor mining houses, the Chamber of Mines ResearchOrganization, and the academic and stockbrokingfraternities. The Committee is therefore well equipped tocontinue organizing stimulating events, and to steer theBranch ahead confidently.

The adverse economic conditions prevailing in SouthAfrica in general, and within the mining industry inparticular, make it difficult to identify original andstimulating topics for presentation at general meetings.Despite these difficulties, the topics presented over the pastyear were of a high standard and each generatedconsiderable interest from members. These wereas follows:July 1991 The Minerals Industry in South

America by Dr O.K.H. Steffen

The Channel Tunnel by Mr R.J.RobbinsEngen by Mr R Angel

Joint presentation by LTA ProcessEngineering/Revere Resources by MrT. Ryan and Mr G. Laing

May 1992 Alusafby MrR Barbour.

On most occasions, attendances exceeded 200 personsper event. The Branch's appreciation to all speakers fortheir efforts in preparing their presentations should beplaced on record. In each case, the post-presentationcocktail parties were generously sponsored by companiesassociated with the speakers.

During the past year, presentations honouring fifty-yearmembership were made at general meetings to Messrs RC.Espley-Jones and V.O. Steed.

Four one-day technical visits were undertaken during thelast 12 months:

September 1991

November 1991February 1992

Modderfontein explosivesfactory (AECI)

Zinc smelter, Zinc Corporation ofSouth Africa

Impact ripper, Kloof Gold mine

Metallurgical processes,Magaliesburg Foundry.

The attendances varied from 13 to 30 persons. Withoutexception, the visits were of an interesting nature and weregraciously hosted by the companies concerned.

The Branch organized another very successful students'function in August 1991, hosted by Anglovaal, at whichstudents from the Mining and Metallurgical Departments at

In conclusion, the Branch would like to extend its thanksand appreciation to the Secretariat for their assistanceduring the past year, together with their enthusiasm andencouragement. Appreciation is also extended to theCouncil of the Institute for their support throughout theyear to the Branch and its programme of activities.

The AGM of the Branch was held in the canteen of thePresident Brand Mine on 17th July, 1991. The meeting waswell attended (68 persons including members and guests).Mr Mosenthal, President of the SAIMM, was especiallywelcomed to the meeting. The guest speaker for theevening was Mr Jim Buys, the Senior Economic Consultantof Anglo American. His address was entitled 'Thedeterminants of the gold price and possible futurescenarios'. The talk included the history of the gold price,and the effect of levels of production of the metal. Heattributed the general smoothing of the gold price to thecontrol of inflation and growth rates by the governments ofthe Western World, which thus reduced the monetary valueof gold as a hedge against inflation. The future of the goldprice was forecast to remain stable as long as there wasmajor selling by the holders of large stocks of gold, but thelong-term view was that the price would show a slightimprovement as supply and demand factors becomemore balanced.

The Branch continues to meet on a regular bi-monthlybasis for general meetings and mini-visits to places ofinterest to its members. The addresses at the generalmeetings cover matters of topical interest to its membersand guests. Three technical visits were held during the year.

The first was to Dorbyl Heavy Engineering,Vanderbijlpark, on 11th September, 1991, which wasattended by 22 persons. The party was shown around thethree major works of the company. These are the Brodericksection, where mechanical engineering is carried out, theDuncanville works, which is the largest fabrication plant inSouth Africa handling major construction work, and theVanderbijlpark works. This last carries out integratedjobbing contracts and specialized foundry works. Dorbylset up an impressive visit, which demonstrated where verylarge items are manufactured for the mining andmetallurgical industry.

The second visit, which was attended by 24 members andguests, was to Loraine Gold Mine on 15th January, 1992.The group was met by Mr Jan de Witt, the Mine Manager,who explained the chamber-stoping method, which wassubsequently visited. The underground visit to these stopes

was an eye-opener to those who are used to undercutstoping in that the stopes are some 25 metres in extent in allthree dimensions. The area where the chambers are beingmined is not stressed, and the sidewalls and hangingwallsare supported by grouted rods and tendons. The miningefficiencies by this method are some 30 per cent better thanin conventional stoping.

The last mine visit of the year was held on 20th May,1992, to Vaal Reefs No. 11 shaft Moab project. Fourteenmembers and guests visited the site. The mine personnelgave a presentation on the history of the project, and on themethods being employed to ensure that the project iscompleted at the lowest effective cost. The shaft pillar is tobe mined before the shaft is in production, which raised afew eyebrows among the members present. The wholeoperation is being carefully monitored to ensure nowastage, and equipment from other shafts is being re-used.

The annual visit was postponed so as to coincide with theSouth African Tunnelling Symposium, which is to be heldat the Highlands Water Scheme in September 1992.

In addition to the Annual General Meeting, two generalmeetings were held during the year. The ftrSt was held inthe Unicorn Club, St Helena, on 31st November, 1991. DrB. Brink, Medical Superintendent of the ErnestOppenheimer Hospital, Welkom, addressed the meeting of31 members and guests. The title of the talk was 'Thefunding and provision of health care in the mining industry'(or 'What's wrong with the MBS and how to fIX it'). DrBrink explained the existing structure of the differentmedical services, and highlighted the mal-distribution ofexpenditure with particular reference to the new SouthAfrica. He explained the difference between medical-aidand medical-benefit schemes, and emphasized the need forprimary health care, maintaining that the best investment isin health education. Dr Brink summed up his talk bysuggesting a new scheme in which each employee wouldselect the level of medical facilities that he/she is preparedto pay for over and above an acceptable minimum standard.

The second general meeting was held at the singlequarters of the Beatrix Mine in Virginia, where GeneralCalitz of the South African Police gave a talk on 'The fightagainst theft and mining-industry crime, and the safety ofOFS Goldfields home-owners'. General Calitz emphasizedthe need for public awareness and co-operation with thepolice, stating that the crime rate in the Goldfields was ingeneral coming down. He added that the co-operationbetween the mines and the SAP was good, but there wasconcern about the growing number of gold and copperthefts being reported.

Two presentations were made at the general meetings tomembers of the Institute. Professor L. Bok received a lapelbadge honouring his 50 years of membership. He joined theInstitute in February 1940, and has followed adistinguished career in the academic world at theUniversity of the Orange Free State for some 40 years. MrJ.G McCallum, a long-serving member of the Branch,retired at the end of May 1992, and was presented with aset of cuff links in appreciation of all the work he put intothis Branch both as loyal member and as a holder ofportfolios on the Committee.

The fifth colloquium of the 'Survival 91' series was

hosted by the Branch on 16th June, 1992. Because of thetremendous level of support, the day was a success and wasenjoyed by one and all. Five papers were presented, and apanel discussion was held. There was high level ofaudience participation, and debates on a number of topicsled to enhanced understanding of the topics of the day. Theguest speakers were as follows:

RD. Beck President, South African Institute ofMining and Metallurgy

The Pretoria Branch again had a most successful year,during which several meetings and other functions wereheld. The Committee functioned well as a result of theenthusiastic support and co-operation of all its members.Four committee meetings were held during the year.

The Annual General Meeting of the Branch was held on24th July, 1991, at the Sports Centre of the University ofPretoria, and was attended by some 50 people. Mr RichardBeck addressed the meeting on the status of metallurgythrough the ages and his vision for the future of theprofession. This was followed by a cocktail partysponsored by Iscor.

The Branch, together with the Departments of MaterialsScience and Metallurgical Engineering and of MiningEngineering, again presented a series of MetallurgicalForums. These were highly successful, and papers werepresented by prominent persons from the metallurgicalindustry. About 40 to 50 people attended each of thesemeetings, and the informal cocktail parties that were heldafter these events served as a social get-together for Branchmembers. The good attendance at these events of thestudent members is encouraging, since this is an ideal wayfor them to be introduced to the professional and socialactivities of the Institute. The concept of a mini-symposium, consisting of a few lectures followed by acocktail party, is popular, especially with members residingoutside Pretoria.

Mr T. von Moltke and Or J. Smuts, both of Iscor Research,gave lectures on 'Toepassing van oppervlakanalise in diestaalindustrie' and 'Die SEM as 'n instrument inmetallurgiese ondersoeke' respectively at a meetingpreceding the AGM on 24th July, 1991. Dr W.H. vanNiekerk, of Iscor Research, gave a talk on 'Ontfossing enontswaeling van vloeiyster' on 21st August, 1991. On 18thSeptember, 1991, Mr J.M.A. Geldenhuis, again of IscorResearch, gave a talk on 'Elektrochemiese meting vansuurstofpotensiaal in slak/metaalsisteme'.

The Branch paid a very interesting visit to the SouthAfrican Mint at its new premises in Gateway Park on 13thNovember, 1991, which was attended by 35 people.

Or A.K. Haines, Chief Executive: Mineral Technology ofGenmin, gave a talk on 'Mineral processing research in the90's-Where to?' on 26th February, 1992. He highlightedthe problems facing the industry, but also indicated theopportunities for the courageous. On 18th March, 1992, MrJ.B. Raath, Government Mining Engineer, gave a talkentitled 'Wetsaspekte van mynbou in Suid-Afrika'. Hegave an in-depth view of the implications of newlegislation and of its likely impact on mining activities.This was followed by a multitude of questions from theprospective miners in the audience.

A mini-symposium on corrosion was held on 22nd April,1992, and was attended by 76 people. It included lecturesby Prof. RF. Sandenbergh on 'Spanningskorrosie-krakingin HzS omgewings'; by Prof. P.C. Pistorius on 'Putkorrosiein roesvrystale'; by Prof. W. Skinner on 'Dampfaseinhibitore'; and by Mr T. von Moltke on 'Korrosie-implikasies van hittetint by roesvrystale'. The cocktailparty was sponsored by Sasol.

The Branch was also involved in the annual Hendrik vander Bijllecture, which was given by Or Jan Visser, of theNational Productivity Institute, with the title'Vervaardiging in Suid-Afrlka-Remskoen of Dinamo?' on20th May, 1992.

The Committee is satisfied with the format of the eventsthat they hosted this year and with the attendance. Theywould like to involve more of the senior members, andinvite them especially to attend the AGM. They would alsolike to foster the involvement of technikon students inBranch activities, and would specifically invite them toattend future meetings.

On 6th February, 1992, Dr Visser's presentation entitled'How to increase productivity' was attended by 50delegates. On 25th March, Mr Clem Sunter presented'South Africa: The High Road, Low Road-The Next 5Years and Beyond'. These talks were very well received,and both meetings were well attended.

Forthcoming breakfast meetings will includepresentations on 'Effective human relations skills' on 9thJuly, 'Quality-a team effort' on 13th August, and'Effective labour relations' on 27th August.

To date, two technical evenings have been held:'Welding of stainless steels' on 26th March and'Developments in plasma-cutting technology'. Theattendance averaged 35 delegates per meeting. Bothtechnical meetings were held at the Iscor Club,Vanderbijlpark, and were followed by cocktail parties. Thetechnical evenings have been very well received.

Forthcoming technical evenings include 'Hardfacing: 1.Roll reclamation 2. Refurbishing of mine equipment' on25th June, and 'Weldcare-grinding, polishing, and buffing'on 16th July, 1992.

Forthcoming industry/work visits include one toSamancor on 11th June, and one to Rayweld and Raysonicson 23rd July. Dates for the visits to New Vaal Collieriesand Eskom 's Lethabo works have still to be arranged.

The Branch has been very active as a result of thecommitment and support of its Committee members, and ofthe President, in-coming President, Secretary, and RegionalDevelopment Secretary of The SAIMM. The generousassistance of Ms Ruth Welensky and Ms Sheila McClure ismuch appreciated.

The Committee held five meetings during the year to dealmainly with the meetings and activities of the Branch,which are centred effectively on the Universities ofStellenbosch (US) and Cape Town (UCT) and theassociated Chamber of Mines Western Cape MineralsProcessing Facility.

The main event of the year was the 10th Annual MineralsProcessing Symposium, organized jointly with the twouniversities, which was held on 1st and 2nd August, 1991.As an experiment, the organizers had decided to extend thisevent to two full days, and to invite speakers from othercentres to present papers. A total of 26 papers weredelivered. The Symposium opened with a plenary lectureby Prof. E.T. Woodburn of Manchester, and ended with afascinating description of some early mining sites in theWestern Cape by Prof. P. Spargo from ucr.

This Symposium aroused much interest, and 133delegates attended, which is close to the maximum that theVan Riebeeck Hotel at Gordon' s Bay can accommodate.The AGM and dinner were addressed by the President, McH.G. Mosenthal, who also presented lapel badges tomembers of 50 years' standing. The Branch thanks SA

Cyanamid and Senmin for their most welcome sponsorshipof this Symposium.

A very successful symposium on artificial intelligencewas held on 24th April, 1992, at US, which was attendedby 46 delegates. Ten papers were presented relating to themetallurgical, chemical, and power-generation industries.

The Branch helped to sponsor a visit to operating minesin the northwestern Cape by 24 students from ucr and USduring the short vacation at the beginning of April 1992.We are very grateful to the managements of O'okiepCopper, Black Mountain, and Kleinzee Diamonds, whoarranged visits to their mines and accommodatedthe visitors.

Schools Days were organized at UCT and US on 4thMay, 1992. The attendances at both were lower than at theprevious year's meetings because of the late posting ofnotices about the event

A most successful function for students of the twouniversities and the local technikons was arranged jointlywith the local branch of the SA Institution of ChemicalEngineers at Stellenbosch on 27th April. A most interestingpresentation by Prof. Taite from UCT on failure analysis inmaterials was followed by some traditional refreshments.

The Branch is most grateful for the support that it receivedfrom Council during the year. As it has no full-time staff, itdepends entirely on the enthusiastic assistance of Mrs MegWinter, the Conference Secretary, and the secretarial staff ofthe Departments of Chemical and Metallurgical Engineeringat US and ucr. The continued interest shown by industryin the Branch's main event, the Annual MineralsProcessing Symposium, is most gratifying.

The Branch believes that exposing students to thechallenges and problems of the minerals industry throughactive research projects, symposia, and visits to mines is animportant and useful function.

This year was been a good year for the Branch, and allconcerned with the Branch's activities showed greatsupport and interest. In addition, it was a historic year inthat the name of the Branch was changed from the formerWitbank/Middelburg Branch to the all- encompassing nameof the Eastern Transvaal Branch.

Several functions were held during the year: two paperson pollution and rehabilitation were presented atVandyksdrift Recreation Club in October; a ladies'evening, with a paper given by two of our member's wiveson diamonds as an investment, was held at SA Coal EstatesRecreation Club in February; and two papers, one oncomputer management systems and the other on processcontrol, were presented at the Greenside Recreation Qub inMarch. The 'technical' year ended with a well-organizedunderground visit, together with the presentation of fourpapers from Secunda Mines.

The year is being rounded off with the AGM and asupper hosted by Highveld Steel at their Recreation Clubin Witbank.

In general, the attendance at all the meetings and visitswas very good, but in the coming year a major effort isneeded to convert the large number of guests to members.

This year's Committee will prepare a schedule of events forthe coming year, and will organize the first technical meeting,which will be held at Bank Colliery. This is to relieve theincoming committee of having to organize an event earlyin the year, when they are still establishing themselves.

It is felt that the Eastern Transvaal Branch can only gofrom strength to strength if the interest and support shownduring the past year continues.

5.1.1 ControllingExecutiveMr C.M. McMillan succeeded Prof. A.N. Brown as

President in January 1992.The future role of AS&TS was debated this year. Two

distinct functions were highlighted. One is the estate,facilities, and services function associated with theObservatory site. The other is the learned society function.

The latter activities have failed to live up to theexpectations embodied in the AS&TS mission statementand objectives drawn up a few years ago. The importanceof the learned society function to provide the clear voice ofscience, technology, and engineering in the interests of theSouth African economy was re-affirmed. The AS&TSControlling Executive considered that, for AS&TS to serveits purpose, it must be a meaningful joint venture betweenorganized engineering and science. With this in mind, ameeting was held between representatives of The SouthAfrican Engineering Association (SA VI) and the JointCouncil of Scientific Societies (JCSS), with AS&TS in thechair. This resulted in a commitment to work together and arecommendation to AS&TS to re-structure its Science andTechnology Committee to provide a forum to develop thisrelationship. The re-structured committee, with Mr RD. Beckas part of the SAVI delegation, met on 25th June, 1992.

The management of the Observatory site was carried outsatisfactorily during the year. Although AS&TS had adifficult financial year, sufficient funds were accumulatedto repay to the AS&TS Trust the loan provided to assist inpaying for the Observatory site. The learned societies arehappy with their accommodation on the Observatory site.

A series of workshops was held under the auspices ofAS&TS, including representatives of SAVI, JCSS, and allthe learned societies, to address the subject of 'EducationPolicy for Technology'. The output of these deliberationswill enable AS&TS to contribute to the National Educationdebate with the full backing of the scientific, engineering,and technological communities.

5.1.2 Science and TechnologyCl.C.J. van Vuuren, Chairman

The highlight for AS&TS during the year wasundoubtedly the way in which the learned societies havecome to make use of the Observatory location.

A specific action aimed at 'Technological Education intothe Year 2000' was launched, based on the PRISECdocument 'Education Policy for Technology'. This actionpromises to bring together the total technological spectrumto voice a single supportive opinion-something that mustbe seen as a breakthrough.

Further action to co-ordinate and integrate the thrust ofthe various disciplines is going ahead with vigour, and willbe reported on next year.

238 AUGUST I SEPTEMBER 1992 Journal of tie South Afu9n Institute of Mining and Me/allurgy

Varioos policy documents concerning technology, education,and training were reviewed, and specific inputs were generatedIncluded in these were PRISEC's Position Paper No. 1 of 1992,the policy document from the Engineering Education andTraining Committee, and the Department of NationalEducation's education renewal strategy.

The Engineering Career Guidance and DevelopmentTrust was a praiseworthy initiative, and deserved moresupport than it received. It was felt that the Trust should bere-instated as a worth-while initiative, and that fundingcould be supplied in a more meaningful manner, includingdonations via this Committee.

During the first full year of operation, ECSA successfullycontinued with the following functions with respect to thewhole engineering profession:. setting the standards for registration

. registering applicants who comply with the standards

. accrediting qualifIcations

. prescribing and enforcing a code of conduct. publishing a tariff of recommended fees for con-sultingwork. proposing reserved work. recognizing engineering institutes. liaising with other engineering bodies.

The South African Institute of Mining and Metallurgy isrepresented on the Council of ECSA and also nominatesmembers to all registration committees and professionaladvisory committees for mining and metallurgy.

During the past year, these committees continued theirimportant work of screening the qualifIcations and practicalexperience of applicants for registration as ProfessionalEngineers. Several training programmes for engineers-in-training, which had been submitted by local mining andmetallurgical organizations, were screened by theCommittees. Assistance continues to be provided bynominees of the Institute in the accreditation of coursesoffered by universities and technikons in the disciplines ofmining and metallurgy.

5.3 The South AfricanEnp,eerlng Association (SAVI)Representative RD. BeckAlternate Dr B.K. Loveday

The structures in which SAVI operates in relation to thelearned societies and vocational groups has been of concernto the Institute. This was discussed with the other learnedsocieties, who re-assessed their positions. This led to anumber of meetings between the presidents andrepresentatives of the learned societies, vocational groups,and SAVI, culminating in a revised structure, which wasaccepted at a meeting on 9th June, 1992. This structureaccepted individual membership of the vocational groups,who are viewed in the same light as the learned societies.The concept of a patron/supporting membership structurefor the vocational groups, in which the learned societies paya nominal annual subscription in return for some form ofrepresentation on the Council of the particular vocationalgroup, was also accepted.

SAVI is to gain control over all centralized engineeringfunctions. Issues relating to education and training, careersguidance, an engineering newsletter, and an engineeringdatabase are to be streamlined and brought under the controlof a centralized structure within the SAVI umbrella. It isappreciated that the revised structure will be effective onlyif a realistic budget is drawn up and funded. Work on this isin progress.

Much of the SAVI Council's efforts were directed at thisrestructuring; although critically important to ensure theunity of the engineering profession, other SAVI activitieshad to be neglected.

The following issues were dealt with by SAVI duringthe year.

EducationThe SAVI industry/FRD education initiative got off to a

very slow start. A business plan was drawn up to try andmeet the requirements for a manpower strategy as definedby SAVI.

SAVI feels that an input from the science and engineeringcommunities is absolutely essential to ensure that anydrafting of a new education policy for South Africa has,highest on its agenda, the need for appropriate technicaleducation for the future well-being of the country. To thisend, SAVI is actively participating in the workshops beingrun under the auspices of AS&TS.

Technology PromotionThe Technology Top 100 Banquet took place on 9th

March, 1992. Prof. Battecharrya, who is the technologyadvisor to the British government, and Minister D. Keysspoke at the dinner. The companies who were judged tohave qualified for recognition because of their contributionto technology were also rewarded. An enthusiastic responsewas received for this recognition, and revised applicationforms are being drawn up to improve on the selectionprocess for the coming year. A National Technology Weekis being planned for September 1993.

Relationship with ECSAThe President of the Engineering Council of South Africa

(ECSA) attended meetings of the SA VI Council, and

Journal of the South African Institute of Mining and Metallurgy 239AUGUST I SEPTEMBER 1992

several areas of close co-operation are being explored. Ajoint SAVI/ECSA document was submitted as comment onthe government's Educational Renewal Strategy.

Relationships with the Scientific Community

The SAIMM conviction that AS&TS should exert itself asthe key player in forging links between science andengineering was strongly supported by SAVI. To this end,SAVI is actively contributing to joint meetings being set upby AS&TS.

In conclusion, although a great deal of time was spent onstructural matters within the engineering profession, closerunity was achieved through the meetings of the presidents.The SAIMM actively pushed for these changes andfacilitated informal meetings.

SAVI is now in a much stronger position to move forwardon issues that are of interest to the whole engineeringprofession at large and critical to the future well-being ofSouth Africa.

5.4 Engineering Career Guidance andDevelopment Trust

The Trust was a joint initiative of the South AfricanEngineering Association (SA VI) and the Society forProfessional Engineering (SPE). The Director of the Trustwas Mc Trevor Geach, and the Steering Committee wasrepresentative of engineering institutions as well as thevoactional societies.

The Trust was mainly concerned with the disseminationof career information, particularly to schools. This waseffected by means of posters and brochures and also by theprovision of an informal information service. Participationin careers exhibitions and organizing the manning ofindividual exhibits were undertaken.

A further concern of the Trust was continuing educationin the engineering profession.

During the 1991192period, the Trust Steering Committeemet on three occasions but became defunct in March 1992.

5.6 Engineering Education and TrainingCommittee

This Committee represents a joint SPE/SA VI initiative,and consists of a number of representatives of learnedsocieties and vocational societies, and also a number ofindividuals who have been invited to sit on the Committeein the light of their experience/expertise in engineeringeducational or related matters.

During the year, a wide spectrum of matters related toengineering education and training were addressed by theCommittee, and a number of exercises were conducted bysub-committees set up for this purpose. The moresignificant of these included the following:

. Transfer of students between technikons anduniversities. Mechanisms to facilitate such moves(particularly technikon to university) were sought

. Experiential (on-the-job) training of technikon students.This mandatory aspect of the diploma course has beenvery problematical in view of the large numbers who donot find employers. Very useful data on enrolment inengineering at technikons and the numbers employedwere collected. Since the problem is directly related tothe economic situation, there are no simple solutions.

. Education and training of technologists. The stage wasreached where formal proposals for the academicstructure and experiential period were widelydisseminated for comment. A sub-committee wasconstituted to collate the comments and to produce afmal document In a meeting with the Chairman of themain Committee, SAARET expressed dissatisfactionwith their minor representation.

. The preparation of an engineering database.

Reports on a number of projects and activities byeducational councils received attention. These included theProgramme for Technological Human ResourcesDevelopment and the Private Sector EducationalCouncil (PRISEC).

5.7 The Association 'of South African RegisteredEngineering Technicians (ASARET)

Representative DcJ. Lurie

ASARET is the vocational society for engineeringtechnicians. During the course of the year, the number ofpatron members of ASARET rose to nine (SAIMM is oneof these). These numbers arebonafide engineering societiesor institutes that pay a nominal subscription to the vocationsociety, and at this stage have two full members on theCouncil of ASARET.

The joint ECSNSERTEC accreditation visits took placein the second half of 1991. Both SAARET and ASARETmembers were involved. The School of Mines' Departmentsof Mining and Metallurgy were visited on 13th and 14thAugust, 1991.

The SAARET/ASARET liaison committee under theconvenorship of Dc Lurie became active during the year,and fulfils the important function of providing a focus onmatters that affect both technicians and technologists. This,it is hoped, will ensure that the two associations speak withone voice on a number of issues.

The affairs of ASRET, the forerunner of the presentorganization, were finally wound up during the year.

5.8 South AfricanAssociation of RegistrableEngineering Technologists (SAARET)

Representative Dc J. Lurie

SAARET is the vocational society for engineeringtechnologists. During the year, Dc Lurie was registered as aProfessional Technologist (engineering) and became a fullmember of SAARET. Hitherto he had sat on Council asan observer.

Besides regular monthly meetings, Council held a one-day 'think-tank' exercise at Rietvley dam on 8th February,1992. This proved very efficacious in clarifying viewpointson a number of issues concerning the future developmentsof the technologists in general and SAARET's future role.Council passed a motion that SAARET would adopt anaggressive pro-active stance vis-a-vis other organizationssuch as SA VI, SPE, etc., that would accentuate theAssociation's leadership role in matters concerningengineering technologists.

A member was delegated to address Master Diplomastudents in the engineering disciplines at each technikonregarding SAARET's activities as well as ECSA and thequestion of registration. Dc Lurie was delegated to fulfIl thisfunction at Wits Technikon. The Mining and Metallurgical,Electrical, and Civil Groups were catered for at a seminarorganized for 25th March, 1992. The entire spectrum ofregistration and membership of professional bodieswas handled.

The question of profile for the technologists wasconsidered on an ongoing basis. There was no consensus inrespect of the education and training, and it became clear thateach discipline will need to formulate its own requirements.

An exercise was initiated promoting regional branchesand special-interest groups. Interested individuals inother centres were identified, and it is envisaged thatbranches will commence operating shortly in Cape Townand Durban.

5.8 Engineers' Liaison Committee

Representative Prof. AN. Brown

Ten learned societies are represented on the PretoriaEngineers' Liaison Committee, which re-elected Mc W.P.Cronje as Chairman.

The 30th Hendrik van der Bijl Memorial Lecture waspresented at the University of Pretoria on 20th May, 1992.Dr Jan Visser, Executive Director of the NationalProducti vity Institute, delivered the lecture entitled'Manufacturing in South Africa: Brake or Dynamo?'

Owing to unforeseen difficulties, the annual socialgathering did not take place.

5.9 Programme for Technological Careers(PROTEC)

The meagre improvement in the national pass rate forblack students from 36 per cent in 1991 gives an accuratepicture of the marginal extent to which schooling improved.The demotivation and frustration in students and teacherscaused by years of crisis and a crippled learning culturemust still be addressed.

The impact of the recession on employment has beenhard, with some reports putting unemployment in the formalsector at over 40 per cent. PROTEC school students reapedthe benefits of technological career development in 1991,and only 13 per cent of the 1454 post-school studentsremain unemployed.

The organization continued to grow despite the difficultenvironment. Six new branches were started, bringing thenumber of operations to 22. Requests were received frommany communities for PROTEC branches. PROTEC hasremained cautious in responding to too many requests inorder to avoid the threat of over-extending their managementand resource capacities.

During 1992 there were 63 full-time staff members, ofwhom 50 were based in branches and regional offices. TheSaturday School programme employed about 250 part-timetutors from industry and education.

5.10 Phoenix National CommitteeRepresentative Dc J. Lurie

The Committee monitors and directs the activities of thePhoenix Programme (originally introduced into SouthAfrica by Mintek in 1973) in conjunction with theEducation Advisory Committee of the Chamber of Mines.The Chamber funds 90 per cent of the programme budget,the balance being funded by SAIMM, AECI, Envirotech,FAPA, Iscor, Mintek, Rio Tinto, and Sasol. These externalcontributions are administered by SAIMM.

The mission of the Phoenix Programme is to contribute ina legitimate and effective manner, to improve the quality andrelevance of science and education in South Africa at thepre-tertiary level. Activities of the programme are conductedin conjunction with the RADMASTE (Centre of Researchand Development of Mathematics, Science and TechnologyEducation) at the University of the Witwatersrand.

During the past year (July 1991 to July 1992), theProgramme was involved in the following activities:

In-service training and support for science-teachereducators on a national basis

Colleges of Education provide the majority of scienceteachers for South African schools. Pre-service training isinadequate and Phoenix has become involved in improvingthe quality of the training. During the period, Phoenixconducted three in-service workshops for science-teachereducators, each over one-week period. On average,attendees numbered 55, representing approximately 3300student science teachers.

The programme implemented resource packages oncopper, manganese, and coal at the workshops and. linked tothese, relevant industrial visits, e.g. for the coal packagevisits to Kriel and Secunda collieries, a power station,and SasoI2).

Phoenix facilitated the establishment of an associationfor science-teacher educators to establish regularcommunication between the educators and to provide aplatform from which they can become involved in decisionmaking within their field

Journal of the South Ahican Indtute of Mining and M8taIJurgy AUGUST I SEPTEMBER 1992 241

In-service training and support on a regional basisRevised versions of the copper and manganese packages

are being produced based on feedback. The package oncopper was presented at science-education conferences atthe Universities of Wisconsin, Oshikosh, USA and at theUniversity of York, UK. The materials were well received,and requests have been received, from interestedorganizations in Australia, England, and the USA

First drafts of the coal and gold resource packages werecompleted, trialed by science teachers, and are now beingmodified.

While the chromium resource package is on hold, thefeasibility of developing a package on iron and steel is beinginvestigated by Iscor in conjunction with the University ofPretoria and Phoenix.

A package is being developed for a compulsory section ofthe general-science syllabus at standard six level, which willinclude possible methods of separation used in the miningindustry.

In-service training for teachersPhoenix conducted the following workshops for

science teachers:. on the gold package at the 14th National Convention for

Mathematics and Science Education, Cape Town-July 1991

. on the coal package-September 1991. two on geology-July 1991 and July 1992. for science teachers in conjunction with JCI-October1991. with the Witwatersrand Branch of the South AfricanAssociations of Teachers of Physical Science forNational Chemistry Week-March 1992.

Workshops on in-service training are being planned for200 science teachers in the western Cape region in August1992, and for 50 science teachers in the Phalaborwa regionin September 1992.

Support for non-formal initiatives in science education

Phoenix funds the meetings of the national executive ofthe South African Association of Teachers of PhysicalScience (SAA TPS). Locally, Phoenix is involved inassisting in the attainment of wider representation onSAATPS and facilitating the unification of initiatives in thePWV region.

Phoenix is launching an initiative in the journalSpectrum to promote science-teacher participation inscience education outside the classroom. The initiativewill provide teachers with the opportunity to share theirideas and classroom experiences in science teaching withtheir fellows.

5.11 South African National Council onTunnelling (SANCOT)

Representative J.A CruiseAlternate D.A.J. Ross-Watt

Civil-engineering tunnelling in Southern Africa wasmarked this year by two major events. The fmt was thestart-up of the long-awaited Lesotho Highlands Water

Project, with its tunnel-boring machines. The secondinvolved the requirement that, with the introduction of theMinerals Act on 1st January, 1992, all civil tunnellingwould fall under the Department of Manpower and beexcluded from mining legislation.

SANCOT held four informal meetings during the year,and the annual seminar held in November 1991 was attendedby 168 delegates. Fourteen papers were presented under thetitle 'The Development of the Underground', the openingaddress being given by the Chief Executive of UmgeniWater, Mr G. Atkinson, and the keynote address byProfessor Broch from the University of Trondheim, Norway.

SANCOT continues to take an active role in the affairsof the International Tunnelling Association, and wasstrongly represented at its General Assembly, which washeld in London.

5.12 The Environmental Planning ProfessionsInterdisciplinary Committee (EPPIC)

Representative J.S. FreerAlternate DJ. van Niekerk

The main thrust of EPPIC's activities over the pasttwelve months was related to the implementation of itsstrategic plan. This focuses on bringing home to plannersand operators in all disciplines their responsibility to takeaccount of the environment, and the potential impact oftheir activities when planning and executing their work. Itshould be noted that this approach is now wider than in thepast, when EPPIC's target was confined to professionalplanners. It recognizes that integrated environmentalmanagement (IEM) should be applied from the cradle tothe grave, and therefore involves people in the board room,and in design, construction, operation, and closure.

In support of this approach, EPPIC widened itsmembership base to include associate membership for thosebodies supporting EPPIC's objectives but whose membersdo not see themselves as principal agents. On this basis,EPPIC welcomed the Environmental Earth Science Group.In addition, the South African Institute of EngineeringGeologists joined EPPIC as a corporate member, and theInstitute of South African Architects rejoined.

EPPIC does not have the resources to reach themembership of its eleven constituent institutes directly, butexpects to do so through the efforts of the representativesfrom each of its constituent institutes. So that theserepresentatives can act effectively, EPPIC hasrecommended that the councils of its constituent institutesshould make provision for their representatives to reportdirectly to Council, and, better still, to set up a Committeefor the Environment as a sub-committee of Council.

Each constituent institute of EPPIC is now effectivelyasked to formulate its own mission, policy, and strategytowards the environment, and to act accordingly. TheSAIMM has led the way in this regard, having set up such acommittee three years ago.

During the year, EPPIC, through ESKOM, conducted asurvey of environmental courses offered by universities andtechnikons throughout the country. A preliminary list ofenvironmental courses has been published and sent to theseinstitutions for updating. Copies are available from theSecretary, EPPIC, P.O. Box 62041, Marshalltown, 2107.

242 AUGUST I SEPTEMBER 1992 JoumsJof lie South Atican Institute of Mining SlId Metallutgy

The response this year to nominations for the EPPICawards was most gratifying both in quantity and in quality.EPPIC's National Premium Award was presented at theWorld Environment Day Symposium on 4th June, 1992, tothe Houwteq Facility Establishment at Haasvlakte-adivision of Denel.

The Symposium itself, on the theme 'One Earth, OneChance', was most successful. It was attended by some 200delegates, who listened to a Keynote Address by ProfessorBrian Hantley and papers presented by Professor StanSangweni, Mr Brian Corbett, Ms Farieda Kahn, Or DaveBeaumont, and Or Alex Weaver. A panel discussion washeld at the end of the proceedings. The Symposium in thepast has been directed at the technology that the engineerand scientist can offer towards the solution ofenvironmental problems. On this occasion, the emphasiswas very much on the socio-economic and socio-politicalproblems driven by the poverty of most of South Africa'spopulation. The message that came out of the Symposiumis that the focus should fall as much on socio-engineerlngas on technology, and should involve the affected peoplesin determining their future.

Mining Congress met in Madrid, Spain. Mr B.C. Albertsand Dr H. Scott-Russell were accepted as new SouthAfrican members on the Committee. A working partyheaded by Mr M. West of the United Kingdom wasestablished to review the aims, goals, and objectives of theWorld Mining Congress and to examine operationalaspects. Major changes to the organization of futurecongresses were considered. The most important of thesewas to increase the time interval between congresses fromthree to four years. Furthermore, it was proposed to moveaway from multi-language congresses and to adopt Englishas the main congress language. The invitation to hold the16th World Mining Congress in Bulgaria in September1994 was accepted.

The 15th World Mining Congress, held in Madrid from25th to 29th May, 1992, was attended by approximatelyWOOdelegates from 30 different countries. The SouthAfrican delegation was well received. The technical part ofthe Congress suffered from poor attendance and theabsence of many of the speakers. A main topic ofdiscussion was the impact of environmental considerationson mining, and the role that the World Mining Congresscould play.

6.3 APCOM '92

National Representative Prof. D.G. KrigeThe 23rd APCOM Symposium was held from 7th to 11th

April, 1992, in the conference centre of the Holiday InnHotel in Tucson, Arizona. This arrangement was veryconvenient for the 200-odd delegates, most of whom stayedin the hotel.

The meeting was organized by the University of Arizona,with Prof. Y.C. Kim as chairman. There were five co-sponsoring companies: three from Tucson and one eachfrom Denver and San Manuel. The proceedings of theSymposium were handled and printed by the Society forMining, Metallurgy, and Exploration, Inc., Liuleton,Colorado. As on previous occasions, this volume isimpressive and contains many original papers of interest toa wide circle of readers.

More than 20 countries from all five continents wererepresented, with a contingent of 10 from South Africa.The main topics covered were exploration, projectevaluation, geostatistics, automation and robotics, groundcontrol, mine design, mineral processing, computergraphics, expert systems, mine scheduling, andenvironmental issues. Some new ideas were presented interalia in exploration, automation geostatistics, minescheduling, and expert systems. Apart from the openingsession, where Prof. A.

6.4 International Ferroalloys Congress(INFACON 6)

Chairman of th£ Organizing Committee Dc RE. Robinson

This highly successful Congress was held in Cape Townfrom 8th to 11th March, 1992. INFACON 6 incorporatedboth the International Ferroalloys Congress and theInternational Congress on Chromium and Stainless Steels.It was organized by a committee comprising members fromThe South African Institute of Mining and Metallurgy,Mintek, and the Ferro Alloy Producers' Association.Mintek Conference Division provided the secretarial andconference management services under the direction of MrsBarbara Watkins, and the SAIMM provided the publicationservices under the direction of Mr John Austin.

Over 500 delegates and over 100 affiliates attended,and a unique feature was that over 50 per cent of thedelegates were from overseas, illustrating the high levelof interest in the potential status of the South Africanmetallurgical industry.

The Congress enjoyed the privilege of a plenary addressby the State President, Dr F. W. de Klerk, who alsoattended a special luncheon to meet local and overseasdignatories. There were also many plenary addresses byinvited overseas speakers.

The full proceedings of the Congress, in two volumes,are available from the SAIMM.

The Congress was held under the auspices of theInternational INFACON Committee, who are responsiblefor allocating future conferences to appropriate venues. Thenext INFACON will be held in Europe in 1995.

6.5 International Chromium Steel and AlloysCongress (lNCSAC 1)

National Representative J.P. HoffmanThe above-mentioned Congress, in amalgamation with

INFACON 6, took place in Cape Town from 8th to 11thMarch, 1992. 587 delegates from 34 different countrieswith, apart from South Africa, the largest delegation fromthe USA, attended INFACON 6 and INCSAC 1.

INCSAC provided a forum for engineers, technologists,

scientists, fabricators, and managers who are concernedwith the production, processing, and applications ofstainless and chromium steels and alloys.

The overall theme of the Congress was 'The Challenge ofthe Future', and the focus was on process technology andthe application of chromium-containing steels and alloys incorrosive, abrasive, and other specialized applications withthe objective of promoting the use of chromium-containingsteels and alloys.

Some 35 INCSAC papers, including those of invited andkeynote speakers, were presented. The papers delivered bythe six invited and keynote speakers were on subjectsspecifically chosen to satisfy the widest possible interests.

In summary, the Congress was a huge success and theinitiative of the South Africans to join INCSAC withINFACON should be fostered and extended to futureINFACON congresses.

The Institute's gratitude and appreciation for the sterlingwork done by the members of the Organizing Committee isherewith acknowledged.

7. MANAGEMENT AND ADMINISTRATION

Portfolio Holder: R.D. Beck

The office accommodation in Cape Towers continues toprove most satisfactory, particularly because of itsproximity to the mining houses. However, there would bebenefits to the Institute, and to the scientific andengineering professions at large, if the Institute were to jointhe other learned societies on the Observatory site.

A once-in-a-while opportunity arose in June, when ahouse adjacent to the Observatory site came onto themarket. The house dates from the days of the miningmagnates, and has the pressed-metal ceilings andcharacteristic architecture of the period. The house, invery good condition, was seen as an economicproposition for letting, and therefore a sound investment.In addition, conversion into offices to accommodate theInstitute Secretariat will not be too difficult. FutureCouncils will no doubt debate long on whether such amove is warranted.

Council members and the Secretariat continued to liaiseclosely. The following staff are employed in servicing theneeds of the Institute and its members: Mrs CelesteMackintosh (Manager), Miss Caroline Jansen, Mrs SamMoodley, Mrs Karen Norman, and Mrs Anna Panana.

Mrs Pam Smith, who had worked with the Institute foreight years, left during the year. She and her husband havemoved on secondment to Brazil.

Mrs Chiz Judge joined the Secretariat in September tooperate the desk-top publishing system, and Mrs SusanLuddick in December to replace Pam. Mrs Claire Kearneyworked on a part-time basis to meet high workloads, particularly in the publication of theINFACON proceedings.

Use of the desk-top publishing system took some timeto settle down but is now working well. Benefits havebeen seen.

7.1 Forward Planning Think Tank

Three issues that required greater consideration wereaddressed in a 'Think Tank' on Saturday, 18th July, 1992.The following issues were contemplated:. the future relationships of the SAIMM and the other

bodies in the mining industry. the Institute's Journal, and the need to provide a morereadable publication to communicate with the broadspectrum of members of the Institute. book publications and the reasons for difficulties ingetting new titles into print.

The deliberations were useful, and some conclusionswere reached. Plans were made to move forward with theseissues in the coming year.

7.2 Finance

J.A. Cruise, ChairmanRG. MosenthalDc H. Scott-Russell

The Institute relies on income from schools, colloquia,symposia, and conferences to maintain its subscription feesat an acceptably low level. Despite the current economicclimate ruling in the country and the fact that no singlemajor conference was held during the year, the Institute wasable to declare a net income ofR40 132 for the year.

This can be attributed to. the introduction of a series of five one-day colloquiaaddressing problems currently being experienced by themining industry, namely the successful Rescue 91 series. the containment of the Journal expenses, which hadthreatened over the past few years to run away; cost-saving procedures were implemented and started toshow results in the second half of the year.

Further steps in cost-containment were implemented, withthe introduction of an in-house desk-top publishing facility,which was installed during the year, the benefit of whichshould be realized during the forthcoming year.

The book value of the Institute's investments increased byR135 038. The market value of these investments increasedfrom RI 743 225 to R2O45 175, reflecting a satisfactoryperformance of the investment portfolio.

Towards the end of the fmancial year, a property adjacentto the AS&TS site in Observatory came onto the market.The Institute negotiated to purchase it, and its final offer ofR575 000 was accepted. The acquisition of this property isviewed as a strategic medium-term investment

Departing from previous years' policy of automaticallyredistributing investment income to the various funds thatare operated by the Institute, this year it was consideredprudent to create a new fund with this income, namely theCentenary Fund, in anticipation of the Institute's centenaryyear in 1994. An amount of R35 000 was transferred to thisfund to create an opening balance.

Thanks are due to Martin & Company, who continue toact as the Institute's investment advisors; to the secretariesfor their continued efforts in containing costs; and to theaccountant and auditor for the excellent financial servicesrendered during the year.

They are Gordon Miller, Production Manager,Western Areas Gold Mining Company Limited, andBernard Swanepoel, Manager: Mining, Kinross MinesLimited. The two winners would travel to Portugal, Italy,and Sweden at the end of August, where they would visitmining projects of interest

To date, 23 recipients have benefitted from this TravelGrant, which is awarded annually to two young miningengineers who have attained excellence in their field. TheGrant is made under the auspices of The South AfricanInstitute of Mining and Metallurgy, who appoint acommittee to select the winners. With this Grant, Delfos &Atlas Copco consider that it is putting something back intothe industry from which it makes its living.

The awards function was attended by some 230 people,who represented the top echelons of the South Africanmining industry.

MASSMIN 92

The papers selected for this Conference cover a broad range of topics. Orebody access andinfrastructural requirements are discussed. There are equally strong sections on the operationsusing primary drilling and blasting-stoping techniques, and those relying on caving for primaryfragmentation. The drilling and blasting section, which includes the monitoring and control ofthese procedures, provides insight into current trends. Excavation and support designs are welldocumented, particularly in poor ground conditions subject to significant changes in stressenvironment The selection and operation of equipment, particularly with regard to maintainability,is an interesting section. The papers in the coal section are of direct relevance to massive mining,and many also apply to coal.

The people factor has been just as important. The enhancement of training and skills isemphasized. Participative styles of management have been encouraged, and worker groups havebeen empowered to make their own decisions and recommendations to management Relationshipswith suppliers have improved, and this closer liaison has resulted in better-designed equipment,This is leading to the increased up-time of equipment, greater reliability, and bottom-lineimprovements.
