Reasons for Improvements in Rock Related Safety Political – change in government –Leon Commission(1995) –Mine Health and Safety Act(1996) Tripartism (Unions, DMR and Employers) Employers – Chamber of Mines Suppliers – better support Rock Engineering fraternity Targets and Milestones (2003) The Mining Charter(2004 & 2010) CoM MOSH Learning Hub(2010)

Duncan Adams Rock Engineering CoM Learning Hub Identify leading practices in the industry related to health and safety and facilitate wide- spread adoption in the industry Three leading practices for rockfall prevention have been identified –Entry examination and making safe –Netting with bolting in tabular stope faces –Trigger Action Response Plan (TARP)

Duncan Adams Rock Engineering

Possibilities Three leading practices in various stages of use in the industry may have prevented 74 fatalities –Correct entry exam/barring – 16 fatalities –TARP – 46 Fatalities –Netting with bolting – 12 Fatalities A worrying 48 rock related fatalities may have been due to a lack of permanent support or temporary support

Duncan Adams Rock Engineering In Conclusion ZERO HARM

Duncan Adams Rock Engineering

Benchmark for Negligible Risk Annual Frequency of a fatality by natural causes of a young American aged between 10 and 14, which represents the lowest health risk population group. This annual frequency is or 1 fatality in young people or 0.1 per 1000

Duncan Adams Rock Engineering South African Mining Rates Coal 0.32 per 1000 workers Platinum 0.24 per 1000 workers Gold 0.45 per 1000 workers All Mines 0.28 per 1000 workers What happens when we get below 0.1? Do we continue to insist on trying to achieve zero and compete with the airline industry? Workers may be far safer at work than at home!
