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.
