金属矿采空区勘查中高密度电法的应用分析

Application of High Density Resistivity Method in the Bauxite Deposit in the Goaf Area

应用高密度电阻率法对山西某地下铝土矿采空区的探测,通过对铝土矿采空区可能出现的高低阻采空异常特征分析,对采集的数据用特定计算软件进行反演成图,并进行异常规模位置大小确定,通过后期钻探验证,表明高密度电阻率法是铝土矿采空区调查评价中的一种行之有效的探测方法,并为采空区的进一步加固治理提供可靠的科学依据。

This paper presents a case history of the application of the high-density-resistivity method to the exploration of Shanxi bauxite deposit in the goaf area.The vertical and horizontal limits of the bauxite mine were determined from back analysis of the abnormal effect of the high and low resistance values.The deposit limits determined by the high-density resistivity method were also verified by the exploratory borings.The results indicate that the geophysical exploration method is a reliable method in the exploring the bauxite mine deposit in the goaf area.
