摘要
针对岩石受荷载变形的电阻率变化、各向异性变化等现象的分析,目前大多为实验分析和理论研究,通过井下综合物探技术对井下高应力集中区的分析研究较少。着重介绍了在煤矿超前探测中,遇到高应力集中区时,采用瞬变电磁法和雷达进行综合物探的方法和过程,以及如何进行打钻验证,为相关的实验分析、理论研究提供实例依据和支撑。
At present,the analysis on the resistivity change and the anisotropic change of the rock loading deformation was mostly carried out by the experimental analysis and theoretical study,and the study on the high-stress concentration zone through underground comprehensive geophysical prospecting technology was less.This paper emphatically described the method and process of using the transient electromagnetic technique and radar for comprehensive geophysical prospecting in the advance detection in coal mine when the high-stress concentration zone was encountered and it also described how to carry out the drilling verification,which provided basis and support for the relevant experimental analysis and theoretical study.
