我矿是一个处在淮南矿区由缓倾斜煤层转向急倾斜煤层的扭转地带,地质构造复杂,具有双突危险的矿井。采煤方法种类繁多,有柔性掩护支架、单一长壁、倾斜分层和老法采煤等。而回采工艺主要是炮采。在采煤、开拓、掘进等工作面使用的电煤钻达70多部。1978年以前,我矿由于电煤钻及电缆管理不善,每年发生的电煤钻电缆放炮(短路)出火事故不少于3至5次,甚至7、8次,严重威胁我矿的安全生产。针对这一薄弱环节,我们加强了电气管理,严格了制
Mine is a mine in the Huainan mining area from gently inclined seam turning steep coal seam twisting zone, the geological structure is complicated, with double sudden danger of mine. A wide range of mining methods, a flexible shield bracket, a single longwall, inclined stratification and the old method of coal mining. The mining process is mainly mining mining. In the coal mining, pioneering, driving and other work face using more than 70 pieces of coal drilling. Before 1978, due to the poor management of electric coal drilling and cables, the accidental blasting (short-circuiting) of electric coal drilling cables occurred every year occurred in mine not less than 3-5 times, or even 7-8 times, which seriously threatened the mine’s safe production. In response to this weakness, we strengthened the electrical management, strict system
