| Summary | The Ground-Tunnel Wide Field Electromagnetic Method (GTWFEM), which employs a ground-based controlled source and tunnel receivers to acquire full-space frequency-domain electromagnetic field responses and subsurface electrical structure information, has the potential to enhance the accuracy of deep mineral exploration. We first introduced the basic principles of the GTWFEM, derived the calculation method for the full-space frequency-domain electromagnetic fields and their corresponding full-wave apparent resistivity. We also conducted research on the denoising data processing method and the three-dimensional inverse algorithm for the tunnel observation. We have carried out a case study of GTWFEM in Dongguashan Copper mine, China. The results show that effective controlled source response data can be obtained in a kilometer underground, which proves the feasibility of the method. |
