Mine electromagnetic wave exploration is widely used in coal mine geology and water prevention and control work. In this paper, taking No.10905 Face of Jingu Coal Industry as an example, through radio wave tunnel perspective and transient electromagnetic detection technology, the internal structure of the working face and the water abundance situation of coal and rock strata in a certain range inside and outside the working face were detected, so as to make production plan in advance, drain the water abundance area in time, reduce the occurrence of water outburst accidents, and ensure the safe and smooth mining of the working face. The study was of great significance to the safe production of coal mines.
