Study on Safe Use of Explosives in Coal Mines

摘要

The main causes of gas explosion caused by blasting operation of explosive in coalmines were analyzed; the explosion limits, ignition temperature and ignition delayed time of gas were studied, then the basic conditions of gas explosion were determined. On the theoretical basis of explosion conditions, the selected principles of explosives used in coalmines were analyzed and the prevention measures against gas explosion caused by blasting operation in coalmines were put forward.
