物探技术在煤峪口矿406盘区防治水的实施

The Implementation of Geophysical Prospecting Technology in 406 Area of Meiyukou Coal Mine

针对煤矿开采过程中存在的采空区积水不明等技术难题,通过物探技术对煤矿防治水工作面进行勘察。由于同煤集团煤峪口矿中15号煤层406盘区地质条件较复杂,盘区上存在一定的采空区积水,提出采用瞬变电磁和高密度电阻率综合探测方法对采空区的积水进行探测,包括具体设计方案、探测作业以及对钻探验证,及时排除安全隐患,为解决盘区煤层的防治水工作提供科学依据。

In view of the technical problems in the process of coal mining,such as the unclear water accumulation in the goaf,the geophysical exploration technology is used to investigate the water prevention and control working face of coal mine.Because the geological conditions of 406 panel of No.15 coal seam in Meiyukou mine of Datong Coal Mine Group are complex,and there is a certain amount of goaf water on the panel,it is proposed to use the transient electromagnetic and high-density resistivity comprehensive detection method to detect the water in the goaf,including the specific design scheme,detection work and drilling verification,in order to timely eliminate the potential safety hazards,and provide scientific basis for the prevention and control of water in coal seam in the panel.
