禹州市大刘山煤业有限公司为兼并重组矿井，存在附近老窑多，采空区错综复杂和部分地点水文地质情况不明等问题。针对这一情况，为保证大刘山煤业安全生产，采用物探与钻探相结合的方法对该矿采空区积水进行探查，圈定了3处电阻异常区，并施工了17个钻孔进行验证和采空区积水疏放，最终疏放积水7.9万m3，有效地保证了后期采掘作业的安全。

Yuzhou Daliushan Coal Industry Co., Ltd. was a merger and reorganization mine. There were many old kilns in the vicinity, the goaf was complicated and the hydrogeological conditions of some places were unknown. In view of this situation, in order to ensure the safe production of Daliushan Coal Industry, the method of combining geophysical detection and drilling detection was used to explore the accumulated water in the goaf of the mine. Three resistance abnormal areas were delineated, and 17 drilling holes were constructed to verify and drain the accumulated water in goaf. Finally, the accumulated water of 79,000 m3 was dredged, which effectively ensured the safety of the later mining and excavating operation.
