摘　　要：介绍了高密度电法的基本原理、视电阻率计算公式和探测装置的类型。针对工区地质资料,设计测线布置,获取完整的测线或测网数据后,对采集到的数据进行预处理和格式转换。剔除畸变数据,反演、绘制视电阻率断面图,最后结合地质资料对异常作出解释。通过华北地区某煤矿采空区的物探数据,绘制视电阻率剖面和平面图,针对异常区进行打钻验证,异常区位置与推测位置相符。探测结果表明,高密度电法对解决煤矿采空区地质问题是一种快捷、高效的勘查手段。In this paper, the basic principle, apparent resistivity formula and detection device type of high-density resistivity method are introduced. In view of the geological data in working area, the arrangement of the measuring-line is designed, and the preprocessing and format conversion on the complete collected measuring-line or network data are conducted. The distorted data is eliminated; the apparent resistivity profile is inverted and drawn; finally the anomalies are explained combining with the geological data. The section and plane plan of apparent resistivity are drawn according to the geophysical prospecting data of a certain coal mine gob in north China, and then drilling testing is done in the anomaly area, the location of which coincides with the sup- posed location. The detection results show that high-density resistivity method can be considered a quick, effective exploration method to solve the geological problems of coal mine gob.
