摘　　要：采空区是产生地质灾害的主要因素之一,危害极大,查明采空区范围对地质灾害的准确评估和预防有着十分重要的意义。瞬变电磁法是一种被广范应用的地球物理勘探方法,其具有对低阻体敏感、施工效率高、适用于各种地形工作等优点。在分析电法勘探理论基础及地电条件上,采用瞬变电磁法成功地探测了某地质灾害评估区内铝土矿采空区位置,验证效果明显,为该地区地质灾害评估工作提供科学的依据。Mine goaf is one of the main causes of geological disasters,and it causes great harm to human. It has very important significance to evaluating the geological disasters accurately and preventing the geological disasters that explore the scope of the mine goaf. Transient electromagnetic method is one of the geophysical prospecting method,which is used widely. Transient electromagnetic method has many unique advantages such as it is sensitive to the low resistance body work,has high efficiency of construction,suitable for all kinds of terrain detection work,etc.In this paper,the situation of bauxite goaf in a geological disaster assessment area is explored successfully by using the transient electromagnetic method,based on the analysis of electrical prospecting theory and ground geoelectric conditions.The effect is very well according to the verification.The result of detecting the bauxite goaf can provide scientific basis for the geological hazard assessment work.
