摘要
本文将井下瞬变电磁法运用到铜镍矿的采空区勘查工作中,简述了该物探方法的工作原理,在实地工作过程中,通过井下采集、数据处理、反演成图,在异常解释及对采空区位置的推断与前期所圈定的范围基本相一致,充分验证了方法的准确性和有效性。综合研究发现,将井下瞬变电磁法应用于地表存在塌陷的矿区具有重要意义,既满足了勘查目的,又保证了安全施工,为矿区隐蔽治灾工作提供物探数据支撑。
In this paper,the underground transient electromagnetic method is applied to the investigation of the minedout area of copper-nickel mine,and the working principle of the geophysical prospecting method is briefly described.In the process of field work,through underground collection,data processing and inversion mapping,the anomaly interpretation and the inference of the location of the mined-out area are basically consistent with the scope delineated in the early stage,which fully verifies the accuracy and effectiveness of the method.The comprehensive study found that it is of great significance to apply the underground transient electromagnetic method to the mining area with surface subsidence,which not only meets the purpose of investigation,but also ensures the safe construction,and provides geophysical data support for the hidden disaster control work in the mining area.
