Application Case Analysis of Transient Electromagnetic Method in Coal Mine Disaster Investigation and Evaluation
In order to further clarify the area where groundwater hazards are prone to occur in a current mining area,the transient electromagnetic method is used to investigate the underground environment of the coal mine.The survey results show that there may be a water-bearing structural belt in the mining area,which basically runs through the elevation of 550～-200 m,which may be harmful to the development and use of goaf or roadway.In addition,when the transient electromagnetic method is used to survey the mining area,the goaf is often characterized by medium and high resistance surrounded by low resistance,while the water-bearing fracture is often characterized by low resistance.The research content of this paper has certain guiding significance for guiding the development of subsequent mineral resources.
