Application of Transient Electromagnetic Method with Electrical Source in Detecting Water Rich Structure in Coal Mine
The Ziyang fault crosses the mine boundary of Dongtan Coal Mine,providing the possibility for the occurrence and migration of water,posing a potential threat to the safety of mine production.To eliminate safety hazards,the transient electromagnetic method sensitive to low resistance anomalies is used to detect the distribution situtaion of fault water conducting zones within the mining and excavation range,so as to carry out targeted emission governance.The electrical source transient electromagnetic method is adopted,and the grounding wire source is used to effectively avoid the presence of many cultural buildings and transportation lines on the ground surface of the study area,reducing the influence of terrain.The research results indicate that the electrical source transient electromagnetic method can accurately distinguish low resistance thin layers,provide reliable basis for coal mine mining area and mining face design,and thus improve the level of mine safety production.
