杨村煤矿综放工作面过断层技术与管理实践

The Technology and Management Practice of Fully Mechanized Caving Face Crossing Over Fault in Yangcun Coal Mine

针对杨村煤矿321综放工作面的实际地质情况,通过比较综放工作面过断层技术方案,最终采取刹刀破底的方法顺利通过了断层,减少了煤炭储量损失,节省了工作面搬家费用,提高了煤炭回收率,增加了矿井效益,实现了综放工作面的安全高效生产。本文还结合基层单位现场管理实际,介绍了综放工作面过断层期间的安全技术管理,对其它相似工作面过断层提供了参考借鉴。

For the practical geological condition of 321 st fully mechanized caving face of Yangcun coal mine,by compare the technical proposalof fully mechanized caving face crossing over fault,finally take the method of braking to break the bottom to cross over fault smoothly,which cutloss of coal reserves,save the expense of moving working face,improve the recovery rate of coal ,increase the mine benefit and realize the safeand effective produce of fully mechanized caving face.This thesis also combine the practice management of grassroots units,introduce the safetechnology management during the crossing over fault period,which offer referent to the other similar solution
