Application of Res2dmod Electrical Imaging Surveys in Goaf Exploration

  • 摘要: 采用RES2DMOD高密度电阻率正演软件和RES2DINV高密度电阻率反演软件,选取有限差分法正演和最小二乘法反演的处理方法,对建立的三个不同采空区模型进行正、反演计算,研究地质体(采空区)的电阻率响应,并以在焦家金矿望儿山尾矿库区的具体应用为例,验证了高密度电阻率法在采空区勘查中的有效性和可靠性,同时对反演结果做出解释和分析,结果表明高密度电阻率法在采空区勘查中具有一定的效果,最小二乘反演效果较好,可以进一步推广和使用。

     

    Abstract: Using res2dmod high-density resistivity forward modeling software and res2dinv high-density resistivity inversion software, selecting the processing methods of finite difference forward modeling and least square inversion, the forward and inversion calculation of three different goaf models are carried out, and the resistivity response of geological body(goaf)is studied. The specific application in Wangershan tailings reservoir area of Jiaojia gold mine is taken as an example to verify the feasibility. At the same time, the inversion results are explained and analyzed. The results show that the high-density resistivity method has a certain effect in the exploration of goaf, and the least square inversion effect is better, which can be further promoted and used.
