Do You Know What is Conventional DTH Hammers ?

IntroductionNo. 1 Drilling by DTH hammer.No.2 By rotary cone bit this is kind of drilling way with cone bit to rolling and grinding the

rock.No.3 By top hammer. This catalog is mainly introducing the first method of drilling by

Conventional DTH hammer.

DHT BIT MINING TRICONE BIT TOP HAMMER ROCKDRILLING TOOLS

DTH hammer overviewsDTH hammer is a kind of pneumatic rock drilling tools, the difference from others is during

drilling process hammer always stay in the bottom of the hole, impact the rock by bit from hammer directly. High pressure air enter into the hammer through drill pipe, then run out from drill bits, exhaust air are used to blow up cuttings from the bottom of hole. The rotating power acting on DTH hammer comes from rotation motor on the drill rig, the pull force comes from feeding device and transfer the energy to hammer through drill pipe.

DTH hammer basic structuresDTH hammer components: Piston, internal cylinder, air distributor, check valve and drill

bit accessories are installed in the external cylinder, the external cylinder has the top sub connected with its connection thread & wrench , there has a drive chuck threaded to the other end of cylinder. There is spline in the drive chuck which is mainly used to transfer feeding and rotational force to the drill bit. The stop ring controls the axial movement of the drill bit, and the check valve is used to prevent cutting and other foreign materials ingress into hammer in case of air supplying is stopped. During drilling, the drill bit is pushed into the hammer and pressed against the drive chuck, where the piston directly impacts the drill bit for crushing rock. Hammer start to clean the bottom by blowing up when bit lift from the hole.

DTH hammerwoking principle1. Drilling bit press against the rock.2. High pressure air burst through the check valve from drill pipe, enter the front cavity of

hammer.3. The increase of the front cavity volume push the piston to move upward.4. When the piston moves up to a certain extent, the front cavity deflates and the

compressed air enter into the back cavity. Piston keep moving upward because of inertia.5. When the piston to a certain extent, due to the compression of the back cavity and the

increase of air pressure, the piston starts to impact downward which forming an impact stroke. Moves up circles as the above process to achieve impact and complete rock drilling.

No one should discriminate science or he will be abandoned.

Type of DTH hammerClassifying by hammers cutting blowing up way: Conventional DTH hammer & Reverse

Circulation DTH hammer (RC hammer).Classifying by hammers air distribution and structure characteristics: Hammers with valve &

Hammers without valve.Classifying by hammers rated working pressure: Low air pressure DTH hammer(rated

working pressure 彡 0.7Mpa), Mid-Low air pressure DTH hammer(0.7Mpa< rated working pressure ( 1.5Mpa ), High air pressure DTH hammer(1.5Mpa< rated working pressured 2.5Mpa), Ultrahigh air pressure DTH hammer (rated working pressure>2.5Mpa)

Classifying by the assorted bit which with or without foot valve: DTH hammers available for assorted bit which with foot valve & without foot valve.

Classifying by hammers outer diameter: 1 inch, 2 inch, 3 inch, 4 inch, 5 inch, 5.5 inch, 6 inch, 7 inch, 8 inch, 9 inch, 10 inch, 12 inch ,15 inch, 24 inch, etc.,

DTH hammer applicationDTH hammers are widely used in geology exploration, civil construction project, water well

drilling and construction foundation project.

Technical parameters we should know from this catalog.Working air pressure:

Working pressure Standard in metric unit is Bar/Mpa, there has different units in different countries . In Europe and American, generally use PSI (PSI: Pounds per square inch, P—pound, S—square, I—inch) as pressure unit.

In China, generally use Kg/cm2 describes Working pressure, so we should know how to exchange pressure in metric. Now we provide three pressure exchanging principles as below:

1bar〜 14.5psi 1psi免 0.06895bar 1 bar= 0.1 mpa=1.0197 Kg/cmExample: JinDian 45A DTH hammers Working pressure is 1.0-2.5 Mpa, exchange to metric

unit is 10-25 kg/cm2 as JinDian 45A hammer working pressure in metric unit.

Impact frequencyImpact frequency is the rate of the piston impacting, metric unit is HZ(H).

The hammer HD45A as an example in this catalog, indicating the impaction frequency as 30HZ in 17 Bar, which means HD45A hammer’s impaction in per second by 30 times at working pressure 17Bar.

Air consumptionAir consumption is the pressed-air consumed in drilling process, metric unit is m3/min, there

are 2 other units, I/S and CFM. Here we provide below exchange principle.1m3/min=35.4CFM=16.67 I/sWe use the unit of m3/min in this catalog. From the technical parameters of HD45A indicating

the air consumption is 7.0m3/min by 14Bar input , which means HD45A hammer consumes around 7.0m3 air when 14Barpermin as input air pressure.

Mistakes occurred in detail while success depend on system. 02

Domed I Spherical Button Domed /Spherical Buttons are usually used as gauge buttons of DTH Bits, suitable for very abrasive and very hard formations.

©

Concave Face Be suitable for all application ground sp e c ia l fo r m edium hard and homogenerous rock formations. Good hole deviation control and good flushing capacity.

Convex Face Be suitable for soft to medium- hard rock formation with low to medium air pressures. It is the most resistance to steel wash, and may reduce the load and wear on the gauge buttons, high penetration rate but poor hole deviation control.

Flat Face This kind of face shape is suitable for very hard and abrasive rock formations in applications with high air pressures. Good penetration rates an resistance to steel body.

Double Gauge Face This kind o f face shape is suitable for high air pressure drilling in medium to hard rock formations. Designed for high penetration drilling with good resistance on steel body.

Parabolic/Semi-Ballistic Buttons Parabolic Buttons are usually used as gauge buttons and front buttons of DTH Bits, suitable for medium abrasive and hard formations.

Ballistic Button Ballistic Buttons are usually used as front buttons of DTH Bits, suitable for medium abrasive and medium hard formations. They can also be used as gauge buttons if the rock is soft.

Sharp Ballistic Button Sharp Buttons are usually used as front buttons of DTH bits for soft formations providing fast penetration rates and low risk of button break.

Flat B u tton Flat buttons are usually used as protection buttons to against wear on surfaces of DTH Bits.

The Characteristics Of High Air Pressure DTH Hammer

To ultilize bits with footvalve

■ Valveless air distribution. More reliable.

■ Simple design of the piston, long life.

Fewer internal parts, simple structure, longer lifs, less failure and easier to maintain because all spare parts are hardened.

To ultilize bits without footvalve

■ O u t o f the trouble of foot valve fracture caused by expansion and contraction.

■ Lower energy consumption and higher impact frequency. The drilling speed is 15%-30% faster than similar bits but with foot valve.

■ Simple structure, reliable parts, long life, easy maintenance with low cost.

Easy to disassembly because the top sub, and the drive chuck are connected with external cylinder with a multi-step thread.

Lower air and diesel consumption. The diesel consumption is about 10% lower than the bits but with foot valve.

The lubrication of DTH hammerAll internal part must in good lubrication due to high frequency of piston

impaction and precise cooperation clearance between parts, the surface of parts may appears cracks by the friction and heat due to lack of lubrication. The lubrication is very im portant to keep hammer working in maximum service life. Please use proper lubrication oil(machine oil), any uncleanly oil such as used machine oil contain im purity inside which may caused hammer jamming or damaged.

1、DTH hammer lub rica tion purpose :• Reduce fric tion damage of moving parts• Anti- corrosion• Sealing2、Requirements o f q u a lity lub rica tion o i l :• Very strong liquid film intensity.• No smoke and poison gas o u t .• No corrosion phenomena in any conditions.• Lubrication all components quickly.• Lubricate fu lly in high d rilling speed, high & low temperature conditions.• No Adhesive residue in hot & cold air situation.• Very high soluble oil emulsion.

Drilling operation introduction

1„ P re p a ra tio n b e fo re d r i l l in g1} Hose pipe connection :Hose pipe connection is very im portant to ensure the security. We need to fo llow

up below instruction to ensure the high efficiency, reliable and economy of air compression system operation.

• Choose the correct air compressor to ensure sufficient air supplying.• Select correct size hose to connect air compressor and hammer correctly to

ensure the air lose in minimum between compressor and hammer.• There is no air leakage when hose pipe connection.

To share confidence, happiness, hope and convenience to get our great life.

2) D rill rig in pos ition :

W ith the d rilling depth run, the drill rig has risk to fall down if located too close of the hole, move rig away from the hole.

3) DTH hammer and d r ill pipe assemble correctly.

2S D r i l l in g o p e ra tio n keys

In order to achieve the best performance in drilling , we need to focus on four basic parameters: Impaction, Rotation, Feed force and cuttings blowing up. Below is the analysis of how to modify these four parameters to improve the d rilling performance.

Note: For getting the best drilling performance, impact force, feed force, rotary speed and cuttings blowing up should be coordinate and unified, we should adjust impact force of air compressor, rotary speed, then set feed pressure and continuity adjusting setting to keep a stable drilling efficiency in operation without jammed.

Impact forceImpact force determined by impact pressure, higher pressure higher speed and

force. Pressure determined by d rilling depth and rock formation, fo llow ing form analysis suitable pressure by depth and rock formations.

Depth

Now the air compressor's Max. Pressure is 35 bars; this impact energy is very high, if the operator use max. pressure to operate d rilling tools w ith bad control, the machine w ill be broken very quick. So in generally to use low working pressure at d rilling depth 70-100m situation.

Recommenedsetting

Rocktypes

G enera lly we suggest to use max. im pact pressure rock can be crushed; somebody may th ink to use max. pressure fo r drilling , but the pressure adjusted should determined by rock hardness, to use max air pressure and consumption only be set in d rilling hard rock form ation. We should reduce the impact pressure (air input energy) in so ft rock drilling; Otherwise the impact energy w ill become blast wave to damage equipment. Please note that reducing the working pressure w ill not reduce the d rilling efficiency in soft rock form ation drilling.

How to adjust

operation

In general adjust the working air pressure fo r increase the Impact pressure, when d rilling efficiency is low or cutting blow ing up less th a t all w ill result d r illin g b its ro ta tion suffocated, d rille r should always pay attention on d rilling pipe rotation situation.

The best way to solve problem is finding their common ground.

Rotating speed

DTH hammer rotation speed directly affect contact angle o f bits head from last impaction to the next, most suitable contact angle determined to some changeable reasons like: impact force (working pressure), rock hardness, d rilling bit diameter and etc., Perfect rotation speed w ill makes the penetration rate, lifespan of b it and operation stab ility to keep the best balance, and reach the perfect rotation speed with the Max. cuttings load.

The best rotation speed w ill depend on the facts happen. It is one simple method to set the rotation speed by observe the wear status of gage button. The firs t place of wear should be on the top of button means a suitable rotation speed set if the wear part on side o f button (fo llow the side of rotation direction) means too low of rotation. Too fast rotation speed caused b it body wear quickly, the wear position on button appears the back direction o f rotation.

Rotation speed can be adjusted by different rock type and geological condition.

We should reduce rotation speed in fo llow ing situation:

• Bits, hammers and drill pipe worn too quick.

• Feeding force and pressure on d rifte r increased.

We should speed up the rotation rate in fo llow ing situation:

• Drilling output decreased

• Rotary un stable

Pressure of pull feedingThe purpose o f feed pressure is press the bits shank into hammers, which should

be adjusted by rock form ation and drill pipe weight. More d rilling depth, less feed pressure, d rilling pipe load weight is heavy in deep hole, even overloaded, now the /JReverse feed" should be applied in order to compensate i t ' s own load weight.

The drilling machine w ill be shaking if the feed pressure is too low thus w ill damage equipment, now should increase the feed pressure until the d rilling machine working stable.

We should reduce feed pressure in fo llo w in g s itua tion :• Rotation speed too slow, unstable, or even stop.• The hole leaning.

To sum of " love and be loved" Achieves success.

• Drilling rig is not stable or displacement.

If we continuously provide too high feed pressure, the d rilling ab ility w ill be reduced, d rilling pipe also bent serious, d rifte r and drilling string will be damaged probably.

We should increase feed pressure in fo llo w in g s itua tion :

• Vibration

• Unsatisfied d rilling result.

• Spline wear intensify.

• To de term ine w hether the feed pressure is appropria te the key perform ance is th a t checking the d r illin g m ust be continuously, sm ooth ly and no jam m ed.

Cutting blowingIf cuttings blowing unsmoothly, the cuttings may grinded by b it in second time

which resulted in energy loss and reduce efficiency of penetration. Air, water and foam can be the material o f cuttings blowing.

Cuttings blowing is d iffe rent to impaction, rotation and feeding, it isn't continuous activity. If cuttings problems happen, drille r would reduce impacting pressure to decrease penetration rate also use other cuttings blowing materials to help. The capacity of cuttings blowing determined by weight o f cuttings, size and shape of cuttings, if cuttings is too weight and size of cuttings is too big, the cuttings blowing needs to match high requirement, water or foam should be used to help cuttings blowing from bottom to ground surface in the situation. We briefly introduce below cuttings blowing methods by water and foam.

a) By w a te r

The injection water can help to reduce dust po llu tion when in dry hole drilling , but too much water injection may caused contrary results, as matter o f experience, amount o f 0.25L/m3 air is suitable. Too much or too less may both caused the problem. Less water injection may caused cuttings stick on the drill pipes or wall of bore hole and increase the risk of hammer stuck. In order to solve this trouble recommend to inject water into high pressure air to increase cuttings flow ing. Pay attention to increase amount o f lubrication oil at same time during injection water into high pressure air.

which can also act as a sealing hole wall. The concentrated foam is pumped into the compressed air duct in the form of the mixture (recommended to be 0.5-2% concentrate/water)

Big bosom solve big problem.

Mixture input to main air hose through high pressure pumps. The pressure of injection is min. 30 bars/ min. The minimum flow is 20 L/m in.

To avoid corrosion clean up foam in the hammer after o ff drilling . Cleaning can be made by injecting water into the air. A fter lifting hammer out o f hole, blow lubrication oil into drill pipe and hammer few minutes. To disassembly complete hammer to spare parts and wrap grease on for long time storage.

By Foam

Foam to be the material can provide good performance on lifting cuttings especially in fracture ground formations. To lifting cuttings out of bore hole by foam can also help form ing hole wall. The concentrated foam is pumped in air hose as mixture material. (The mixture matching recommend as 0.5-2% of m ixture/water)

The mixture go through high pressure pump into air hose. The minimum power of pump pressure is 30 Bar, the minimum rate o f flew is 20L/minute.

When finish foam drilling recommend to clean foam residual in the hammer by injecting water into high pressure air. A fter lifting hammer out o f hole, to fuel lubrication oil into drill pipe and hammer fo r several minutes. The spare parts is required to disassembly from hammer and greasing for long term storage.

To lead a team must be polite and martial.
