摘要
介绍了杜儿坪矿68302工作面过大断层的方法,即预先在断层下盘掘探巷,用木垛在探巷内形成假顶,辅助液压支架接顶过大断层。该方案解决了工作面过大断层易发生冒顶事故的问题。
Introduced the method of crossing oversized fault at Duerping Mine 68302 working surface,mainly by heading of exploration roadway in advance,with wood crib to form the false roof of the exploration roadway,and to assist hydraulic supports crossing the oversized fault.This method solves the roof fall accident problems while crossing the oversized fault for coal face.
