摘　　要：为探索高密度电阻率法在岩溶探测中应用的技术要点,以某饰面用石灰石矿为例,在概述工程地质条件的基础上,对高密度电阻率法物探过程、数据处理等展开分析,通过对视电阻率二维成像形态及高低阻等的反演分析,进行矿区岩溶分布范围、埋深、大小等解释,并对异常结果进行述评。结果表明,资料解释与钻探结果基本吻合,物探结果可用于矿区岩溶塌陷等地质灾害的防治。In order to explore the technical key points of the application of high-density resistivity method in karst exploration,taking a limestone mine for decoration as an example,the geophysical process and data processing of high-density resistivity method are analyzed on the basis of summarizing the engineering geological conditions.Through the inversion analysis of the two-dimensional imaging shape of apparent resistivity and high and low resistivity,the karst distribution range,burial depth and size of the mining area are explained,and the abnormal results are reviewed.The results show that the data interpretation is basically consistent with the drilling results,and the geophysical results can be used for the prevention and control of geological disasters such as karst collapse in the mining area.
