瞬变电磁技术在探测红三沟煤矿井田内老窑积水的应用研究
|
摘要
呼图壁县红三沟煤矿井田范围内存在老窑且资料不详,老窑积水情况不明,严重影响煤矿生产安全。采用瞬变电磁技术对井田内先前老窑开采5号、7号、8号煤层形成的老空区的积水情况进行了探查,为降低地形起伏及近距离煤层开采对探测成果的影响,资料处理解释过程中采用地形校正及反演解释技术,取得了较好效果,为煤矿后期复工复产起到了重要的指导作用。
There were old kilns in Hongsangou Coal Mine,Hutubi County,and the data were unknown.The water accumulation situation of old kilns was unknown,which seriously affected the safety of coal production.The water accumulation in the old goaf formed by No.5,No.7 and No.8 coal seams Mined by old kilns in the mine field,which was investigated by using transient electromagnetic technology.In order to reduce the influence of topographic fluctuation and close coal seam mining on the detection results,the data processing has explained.Topographic correction and inversion interpretation technology had been used in the process,and good results had been achieved,which had played an important guiding role for the resumption of production in the later stage of coal mine.
