摘　　要：水害是煤矿五大自然灾害之一,严重制约煤矿安全生产。长沟公司15110工作面西侧存在地面三维地震15号煤层采空区和地面电法勘探15号煤层积水异常区,且物探异常区与工作面之间还存在2个正断层构造,断层导水性不明,以上情况对15110工作面回采工作造成极大的安全隐患。为了消除水害隐患,确保15110工作面回采不发生水害事故,长沟公司在15110进风巷施工了2个中长放水钻孔,经过分析钻孔钻探、出水情况排除了该水害隐患,确保了15110工作面安全回采。Water damage is one of the five major natural disasters of coal mines,which seriously restricts the safety of coal production.In the west of Changgou Mine 15110 working face,with goaf detected by surface three dimensional earthquake and water accumulation anomaly area detected by surface electric prospecting in No.15 coal seam,there were two positive fault structures between the physical anomaly area and the face,and the water conductivity of the fault was unknown,which caused great safety hazards to the 15110 face recovery work.In order to eliminate the potential water damage and ensure that no water accident,two medium-length water release boreholes were constructed in the inlet roadway of the 15110 working face.
