| Abstract: | The underground TEM has many advantages such as simple construction, lightweight equipment, fast and sensitive to low resistance target body. It is applied widely in detecting water hazards in coal mine. This paper describes the principles and construction methods of TEM and outlines the geological conditions of a coal mine in Huaibei mining area. At the end of paper,experiments show that the underground TEM in detecting water hazards in coal mine is accurate and reliable. |
