Comments to industry: Mines must ensure roadways are driven, and strata support installed to design, including roadway dimensions. Systems should be implemented to monitor compliance to design. Workers must be vigilant for loose and unsupported coal that is not directly influenced by strata support. When a hazard is identified it should be made safe such as barring down or installing additional support. Mines must have in place systems for the management of dangerous incidents as defined in cl179 Work Health and Safety (Mines and Petroleum Sites) Regulation 2014. Statutory officials should be trained in the implementation of these systems.
