Application of Safety Appraisement of Blasting Operation in Coal Face of Blasting Mining

摘要

The coal face of blasting mine in underground coal mine is a very complicated system of disaster environment, the spatio temporal limit increases the accident probability of blasting operations. So the safety appraisement method of safety engineering was applied. Through marking the potential tendency of the serious injury and the control level, the serious injury possibility of this operation is analyzed, and the safety technical measures and management measures to improve the safety in the implemention are put forward.
