Abstract:At present, transient transformation magnetic method is widely used in coal mine system to mainly solve the problem of groundwater.With the development and progress of science and technology, transient transformation magnetic exploration instruments are roughly divided into two categories. Foreign instruments generally use large source devices with large wire frame; domestic instruments generally use low power low coil, low voltage and high current overlapping return devices.During the operation, the transient electromagnetic emission wire frame and the receiving equipment are seriously affected by electromagnetic interference, and the different working devices have different advantages and different anti-interference capabilities.Through the work research of a mine project in Shanxi Province, it was proved that different working devices to explore near the high-voltage lines can play a complementary role and achieve the purpose of exploration.
