瞬变电磁法在探测煤矿采空区中的应用

The Application of the Transient Electromagnetic Method in the Detection of the Worked-out Section of the Coalmine

煤炭工业的迅速发展,极大地推动了当地经济发展,但由于部分小煤窑管理落后,随意乱采,给当地造成了不少灾害,因此,查明采空区对当地政府防灾、治灾方面的意义重大。根据采空区的地球物理特征,通过实例阐述了瞬变电磁法在采空区探测中的实用性和有效性。

The rapid development of the coal industry has greatly promoted the development of the local economy. However the background management of some small coalpits and arbitrary exploitation caused numerous hazards for the local area. Therefore finding out the worked-out sections possesses important significance for the local governments to prevent and control the hazards. According to the geophysical features of the worked-out sections and by using the actual examples, this paper expounds the practicability and the effectiveness of the transient electromagnetic method in the detection of the worked-out sections.
