Are you tipping into an open stope or back filling open holes?
Do you need to eliminate the hazard of tipping over the edge of an open pit?
In June, 2014 the WA government issued an incident report for a fatal accident that occurred when a manned loader drove into an open stope in April 2010.
The operator of the loader was driving in an underground mine when the loader fell 25 metres over the edge of an open stope. At the time, there was no physical barrier to prevent access to the void.
The report included a summary of required actions to prevent future occurrences and fatalities. The need for higher order controls such as elimination engineering was favoured above administrative controls such as procedures and signage, which are less effective and risk-averse.
The suggested method for managing open-hole mine hazards was to design, construct and locate physical hard barriers to inhibit equipment from accessing the edge of these holes. These should be installed prior to creating an open hole, to secure the safety of staff.
