玉泉煤业属于资源兼并重组整合高水害高瓦斯矿井，15101首采工作面运输顺槽掘进揭露一个陷落柱，为确保矿井安全，需对陷落柱的含（导）水性进行评价分析。掘进采用瞬变电磁法探测陷落柱的含（导）水性，用钻探方法探测陷落柱的范围和含（导）水性，结合矿井水文地质条件及巷道揭露情况，对陷落柱进行了综合评价分析，得出该陷落柱内充填物挤压密实，为不含水不导水的陷落柱。%The Yuquan coalmine belongs to a resources merger and reorganized, integrated high water hazard, gassy coalmine. The ad⁃vancing of No.15101 first mining working face haulage crossheading has revealed a subsided column. To ensure coalmine safety, the subsided column water-bearing (conducting) property should be assessed and analyzed. The transient electro-magnetic method has been used to detect water-bearing (conducting) property, drilling for subsided column extent and water-bearing (conducting) property, combined with coalmine hydrogeological condition and roadway revealed situation carried out integrated assessment and analysis. The result has shown that the filling of subsided column is densely extruded, thus a column without water and not water conducting.
