摘　　要：为了安全高效地解决富水软岩掘进巷道冒顶问题,提出采用新型注浆加固材料马丽散KS对巷道围岩进行注浆加固。该材料除了具有极好的黏结能力外,还可以与水发生反应而膨胀,在北辛窑矿2#层掘进巷道冒顶治理现场应用后,起到了对顶板的止水、充填和加固作用,实现了对冒顶区域的安全高效治理。To solve the problem of roof fall in excavation roadway with water-rich soft rock,the paper proposes the grouting reinforcement of surrounding rock with a new material--Malisan KS of excellent bonding property and expanding in reaction with water,whose field application shows it can play a role in water stopping,filling and reinforcing and realize the safe and efficient control of roof fall area in excavation roadway of Beixinyao Colliery.
