摘要: 高密度电法是探明地下采空区、地下水的重要手段之一,是集电测深与电剖面于一体的勘探方法,具有成本低、效率高、信息丰富、解释方便、观测精度高等优点。结合某磁铁矿的具体条件,采用高密度电法对地下采空区围岩稳定性进行探测与剖析,电法观测剖面采用温纳-斯伦贝谢装置,并结合Res2dinv软件对高密度电阻率数据进行二维反演。通过分析与整理,最终确定井下围岩整体稳定性较好,无需对采空区进行充填,并探讨了影响其探测精度的因素。

Abstract: High density resistivity method is one of the most important techniques of exploration of goaf and underground water.Besides that,it is the one that is combined with the electric sounding and electrical section.Furthermore,it has the advantages of low cost,high efficiency,rich information,easy to explain and high precision.In view of the specific situation of a magnetite,the rock stability of underground goaf is detected and analyzed by adopting the high density resisitivity method.The sections are detected by using the Wenner Schlumberger device.Research of two-dimension inversion of the high density resisitivity datas are conducted effectively by combining with the Res2dinv software.According to the research results,it is concluded that,the stability of Underground surrounding rock is so good that there is no need to take some measures to fill the goaf.In addition,the factors that affect the accuracy of detection of the high density resistivity method are discussed in depth.

Key words: High density resistivity method, Surrounding rock of goaf, Resistivity
