摘　　要：以木瓜煤矿10-2012巷水文地质条件为工程背景,分析了该矿10-2012巷充水条件,试验巷道掘进主要受地表水和顶板含水层影响,设计了10-2012巷掘巷超前探查工程,采用瞬变电探测发现了2处低阻异常区,采用钻孔探水验证消除了水患威胁。同时基于巷道掘进时的涌水情况,提出了工作面开采防治水措施。Taking the hydrogeological condition of No.10-2012 roadway in Mugua Mine as the engineering background,water filling condition of No.10-2012 roadway in the mine were analyzed.The excavation of test roadway was mainly affected by surface water and roof aquifer.The advanced detection project of roadway excavation in No.10-2012 roadway was designed.Two low resistance abnormity areas were found by transient electromagnetic detection.The use of drilling hole water detection verified that the flood threat was eliminated.At the same time,based on the water inflow during roadway excavation,water prevention and control measures for working face were put forward.
