OHSMS – consider the following:

Codes of Practice (SWA)

Incident Investigation – Capture LearningsSubject specific AS &

DMP HIF Audits (e.g. OC & UG

Geotech; UG Mine Fill)

Goal: OHSMS Compliance Certification for technical risk

Hydraulic/ Paste Fill – reasons for failures

Refer to page 371 of Strategy2011 paper:

• Highly technical project in a KISS operating environment• Uncontrollable variables or unknowns• Multi-disciplinary team with limited time & resources,

conflicting interests, contradictory technical terms, etc

Need to perform OHSMS audits & risk assessments: systems, procedures, documentation, organisation, training

Hydraulic/Paste Fill Audit

Refer to page 372 of Strategy2011 paper:

• Fill system design should be holistic• Technical specification & QA

(competent person, clearly defined):– Barricades– Hydraulic/ paste fill specification– Reticulation system

• UG monitoring & documentation

Mine Management Systems - Fill(based on ISOAS 18001:2007 OHSMS audit)

Refer to page 372 of Strategy2011 paper:

Ensure these are in place:• Risk Register• Sufficient resources• Documented systems of work• Incident investigations and documentation• Emergency preparedness• Documented Trigger Action Plans (TAPs)

WHSMS

• Due Diligence & evidence of Duty of Care

• Audits & risk assessments (multi-disciplinary team) gap analysis continuous improvement Learning Organisation
