Application of transient electromagnetic method in the survey of hidden disaster-causing factors in non-coal underground mines
Due to the large number,diverse types,and complex processes of non-coal underground mines in China,some of which have a long history of mining and lack basic data,there are problems such as unclear identification of hidden disaster-causing factors in mines and uneven levels of survey results of hidden disaster-causing factors in various mines.Research has shown that transient electromagnetic method has the technical characteristics of convenient construction,low resistance sensitivity,and deep detection distance.It can identify the location,range,boundary,and water content of historical goaf in underground mines,and scientifically and efficiently support the survey of disaster-causing factors in non-coal underground mines.
