激电测深法在勘探采空区中的应用和分析

Application and Analysis of IP Sounding Method in Exploration of Mined out Areas

激电测深法是一种快速有效、经济无损探查地下采空区的一种地球物理勘探方法,主要通过人工地下直流电场激发,以电测深装置形式,接收、研究地下横、纵向激发极化效应变化的来划分地层和圈定地下采空区位置范围。本文根据工程实例对该方法的技术原理及后期的数据处理推断解释进行研究,分析激电测深在马鞍山市和睦山充填站区探查地下采空区范围的应用,为地下采空区处理和周边边坡的稳定性分析提供科学的依据。

The induced polarization method is a fast,effective,and economically non-destructive geophysical exploration method for exploring underground goaf areas.It mainly uses artificial underground DC electric fields to excite,and in the form of electrical sounding devices,receives and studies the changes in horizontal and vertical induced polarization effects underground to divide the strata and delineate the location range of underground goaf areas.This article studies the technical principle and later data processing inference interpretation of this method based on engineering examples,analyzes the application of induced polarization depth measurement in exploring the underground goaf range in the Hemushan filling station area of Ma'anshan City,and provides scientific basis for the treatment of underground goaf and the stability analysis of surrounding slopes.
