瞬变电磁法探测小窑采空区效果分析

The Transient electromagnetic method to geological survey of goafing of the small coal mine

小煤窑采空区的存在对煤矿区的生产、人民财产安全和工程建设造成极大的安全隐患,通过地球物理方法有效地探测采空区的位置、范围、深度,成为解决上述问题的关键。瞬变电磁法(TEM)具有简便、快捷、对低阻体敏感等优点,在查明采空区方面有着广泛的应用。本文以TEM法在伊犁界梁子整合区的应用为例,分析了其探测采空区良好的地质效果。

Goafing of the small coal mine is a great security risks of production,people＇s property safety and engineering construction. Effectively detecting the location,range,depth of goaf by geophysical methods,is the key to solve the above problems. Transient electromagnetic method（ TEM） has simple,quick,sensitive to the low resistivity body advantages,has extensive application in the identification of goaf. Based on the TEM method application in Yili Liangzi integration area,the geological exploration effect of goaf is analyzed.
