摘　　要：针对传统矿山煤岩层含水率探测技术在隐伏水源空间位置探测方面精度较低,易使煤矿发生水害事故,严重影响煤矿企业安全高效生产的问题,采用并行电法+双巷三维电阻率反演技术对煤矿水文地质与工程地质进行探测研究分析。通过电法探测基础原理分析、煤岩层含水率探测方案整体设计、双巷三维电阻率反演数据处理研究及矿山煤岩层含水率探测方案应用分析,完成了煤矿煤岩层含水率探测方案研究,通过对比A煤矿探测结果与后续生产数据与记录,发现矿山煤岩层含水率探测数据准确率达到98%,符合相关矿山煤岩层含水率探测要求。In view of the low accuracy of traditional water content detection technology of coal rock layers in detecting the spatial location of hidden water sources,water damage accidents are easy to occur in coal mines,which seriously affects the safe and efficient production of coal mine enterprises,the method of parallel electrical method+double-roadway three-dimensional resistivity inversion technology was used to investigate and analyze coal mine hydrogeology and engineering geology.Through the analysis of the basic principle of electrical detection,the overall design of water content detection scheme of coal rock layers,the research on the data processing of two-roadway three-dimensional resistivity inversion and the application analysis of water content detection scheme of coal rock layers,the research on water content detection of coal rock layers has been completed.By comparing the detection results of coal mine A with the subsequent production data and records,it was found that the accuracy rate of water content detection data of coal rock layers reached 98%,which met the relevant requirements of coal rock water content detection.
