摘要
地球物理勘探的基础是被探测体与围岩存在物性差异,煤矿采空区通常会形成不同类型的异常。本文以贵州省某煤矿为例,分析综合物探方法在煤矿水文地质勘查中的应用。其间通过分析区域目标层,选用合适的物探方法,即高密度电测深法和可控源音频大地电磁法,并对采空区电性特征进行测定,对资料进行综合研究,使得采空区探测更加全面、准确。
Geophysical exploration is based on the physical property difference between the detected body and surrounding rock, and different types of anomalies are usually formed in the goaf of coal mines. Taking a coal mine in Guizhou Province as an example, this paper analyzes the application of comprehensive geophysical prospecting method in coal mine hydrogeological exploration. During this period, appropriate geophysical prospecting methods are selected by analyzing the regional target layer, namely high-density electrical sounding method and controllable source audio magnetotelluric method,the electrical characteristics of the goaf are measured, and the data are comprehensively studied, thus making the goaf detection more comprehensive and accurate.
