摘要
采煤后遗留的采空区是对煤下铝勘探工作的隐患,这里采用地球物理方法中的瞬变电磁法解决采空区的空间分布问题。针对采空区特定的地质条件选择了中心回线装置,并结合钻孔资料采用1D、2D反演方法确定了采空区的影响边界。实践证明,TEM方法在采空区勘探当中是一种有效的方法。
Gob left after coal mining is a hidden danger for aluminum exploration.Transient electromagnetic method（TEM）,one of the geophysical method is adopted to solve the problem of spatial distribution of gob in this paper.The central loop is chosed according to the special geological condition of gob.The influence boundary is determined by the 1D and 2D TEM inversion mothod constrained with the drilling data.TEM is an effective method for gob exploration in practice.
