羊场湾井田补充地质勘探区内断层分布广泛，在巷道掘进遭遇断层时，经常出现涌水、流砂，掘进头冒落，伴生泥石流灾害，严重影响了矿井的正常采掘接续。结合井田地质勘查资料，系统分析工程范围内水文地质条件与充水特征，对含水断层开采的突水危险性进行评价，确定断层水探放原则，采取超前加固、导(堵)水、架设 U 型钢棚、锚注、喷浆等工艺，减少了冒顶及次生灾害发生。

Faults are widespreaded in new geological exploration area in Yangchangwan minG ing field.During roadway evacuation in aquiferous faults,such disasters as water inrush,quickG sand,gateway driving face caving and mudGrock flow threaten the regular evacuation.With the aid of geological exploration data of mining area and the hydrogeological conditions as well as waG ter filling characteristics,the water inrush risk during evacuating in aquiferous faults was evaluaG ted to determine the exploration and discharge principle of water in fault.The roof falling and secG ondary disasters were reduced by advanced reinforcement,water conductivity (or water shutoff), setting up of UGtype steel shed,boltGgrouting,guniting and so on.
