Abstract:
In the course of new mine construction or of expanding mine workings, the mine development crews are the first to encounter the realities of stress related strain behaviour of the rock. These hazards are encountered generally before the more comprehensive seismic monitoring and rockburst management systems, common in production areas, are in place. As such, strainbursting must be considered an important hazard facing mine personnel. The nature of such hazards, although broadly foreseeable, is that their occurrence is unpredictable. Using a risk-based approach, Cementation Canada has developed practical guidelines for strainburst hazard awareness for its development miners and shaft sinkers. The objectives are to raise awareness, to highlight observable indicators, and to minimise exposure and mitigate the negative impacts of strainbursting, with the ultimate goal of zero harm. This paper covers the background to this challenge, explains how it fits into the Internal Responsibility System (IRS), and provides details of how the programme is being implemented. It is desired to share this programme to improve safety in our industry and to gather feedback in order to continuously improve upon this initiative.
