摘要
下组煤开采一直受到底板奥灰水的威胁与困扰,本文对泗河煤矿下组煤底板带压开采进行了分析论证,证实矿井下组煤底板带压开采是可行的。同时,针对矿井存在奥灰水顺构造薄弱带突出的可能性的情况,给出了详实可靠的处理措施。
The mining of lower coal group has been threatened with troubled floor Ordovician limestone water,Sihe Coal Group coal mining with pressure are analyzed,proved mine lower coal seam mining with pressure is feasible.At the same time,in view of the mine in Ordovician limestone water along the possibility of tectonic zone prominent situation, gives the treatment measures detailed and reliable,solves the problem of coal seam floor mining with pressure.
