摘　　要：为降低水害给综掘巷道影响,以3502运输巷掘进为工程实例,综合使用物探(瞬变电磁探测)、钻探(长距离探测钻孔)对巷道掘进前方富水区域进行确定及疏排。在对富水区域进行疏排后通过深孔注浆对富水区域及周边导水裂隙进行封堵,后依据巷道掘进期间顶板淋水情况决定是否采用浅孔注浆以及二次注浆。依据3502运输巷现场情况,对综合防治水技术方案进行设计。现场应用后,巷道掘进期间基本不受顶板淋水影响,巷道围岩始终保持稳定,取得显著应用成果。In order to reduce the impact of water disaster on the fully mechanized roadway,taking the excavation of 3502 transportation roadway as an engineering example,geophysical prospecting(transient electromagnetic detection)and drilling(long-distance detection drilling)are comprehensively used to determine and drain the water rich area in front of the roadway excavation.After the drainage of the water rich area,the water rich area and the surrounding water diversion cracks are blocked by deep hole grouting,and then the shallow hole grouting and secondary grouting are determined according to the roof water pouring during the roadway excavation.According to the on-site situation of 3502 transportation roadway,the technical scheme of comprehensive water prevention and control is designed.After on-site application,the roadway is basically not affected by roof flooding during tunneling,and the surrounding rock of the roadway remains stable all the time,which has achieved remarkable results.
