为查明刘桥一矿工作面的水文地质情况及工作面底板的富水特征，重点利用矿井音频电穿透法和直流电法探测煤层底板含水构造，并通过勘探资料处理后的音频电穿透成果和视电阻率成果，结合已知地质资料、水文地质资料综合分析，在工作面底板共发现了2处低阻异常区，并推测其主要是第八含水层裂隙比较发育且相对赋水所致，为煤矿安全生产和建设提供了理论依据和保证。%In order to detect the hydrogeological conditions and water-rich characteristics in working face floor in Liuqiaoyi Coal Mine,the mine voice frequency electrical transmission meth-od and direct current electric method were adopted to detect the coal seam floor water-bearing structure. According to the exploration data processing results of voice frequency electrical trans-mission and apparent resistivity,combined with comprehensive analysis of geological data and hydrogeological data,two low resistivity anomaly areas were found out,and it concluded that de-velopmental fracture and relative water abundance of the eighth aquifer caused the anomaly areas. The study provided a theoretical basis and guarantee for the safety of coal mine production and construction.
