摘　　要：双龙煤矿200综采工作面地表水体下开采,保证工作面安全开采是亟待解决的问题。其上覆岩层中是否存在古河道以及古河道的发育特征情况,必须在工作面回采前探测清楚,并采取必要的防治措施。地面高密度电法是近些年新兴的一种新型阵列勘探方法,具有采样密度高、一次性测量、高分辨率、高精度、信息丰富,解释方便等特点,已广泛应用于煤矿地质勘探及地质构造超前探测中,可有效探测矿井空间中的各种地质异常体,为煤矿提供相应的地质技术保障。以探测200工作面上覆地层古河道为例,介绍了高密度电法工作原理和工作方法,详述了高密度电法探测技术在矿井隐伏构造探测中的应用,为矿井安全开采提供了可靠的勘探成果。The mining under the surface water of the No.200 fully-mechanized mining face in Shuanglong Coal Mine is an urgent problem to be solved to ensure the safe mining of the working face.Whether there is an ancient river channel in the overlying strata and the development characteristics of the ancient river channel must be detected clearly before the mining of the working face and necessary preventive measures must be taken.Ground high-density electrical method is a new array exploration method emerging in recent years.It has the characteristics of high sampling density,one-time measurement,high resolution,high accuracy,rich information,and convenient interpretation.It has been widely used in coal mine geological exploration and geological structure advance detection,which can effectively detect various geological anomalies in the mine space,and provide corresponding geological and technical support for coal mines.Taking the detection of the ancient river channel in the overlying strata of 200 working face as an example,this paper introduces the working principle and method of high-density electrical method,and details the application of high-density electrical method detection technology in the detection of concealed structures in the mine,providing reliable exploration results for the safe mining of the mine.
