The application of underground transient electromagnetic method in the collapse area of copper nickel mine goaf
In this paper,the underground transient electromagnetic method is applied to the investigation of the mined-out 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.
