摘要
二亩沟煤矿矿井4、9、11号煤层奥灰水均局部带压,存在奥灰水突水可能性。针对这一问题,通过对该矿矿井底板突水因素和条件的分析及带压开采安全性的评价,分析评价奥灰水对矿井4、9、11号煤层带压开采是否可行。
Because of partial pressure of Ordovician limestone water in No.4, 9, 11 coal seams in Ermugou Mine, water inrush of Ordovician limestone water might occur. Based on this problem, feasibility evaluation of Ordovician limestone water to mining under pressure in No.4, 9, 11 coal seams was analyzed through evaluation of its security and analysis of elements and conditions of mining water inrush.
