摘　　要：小煤窑的无序无证开采,形成的采空区等地质异常体常成为公路、铁路等工程安全施工和长久运营的安全隐患。为解决上述问题,本文通过对测区浅部采空区采用探地雷达和AGI高密度电法、测区深部采空区采用EH4电磁成像系统的综合物探方法,得到了采空区分布的剖面图,划分了重点异常区,取得了令人满意的探测结果,为后期有针对性、有目的性地对采空区进行治理提供了保障。Disordered mining of small coalpits without a license formed geological anomalous bodies such as the goal which often brings hidden danger to highway, railway and other engineering construction and long operation. In order to solve the problem above, this article applies the comprehensive geophysical prospecting method that it measures the shallow goaf of sensing area by using the ground penetrating radar and AGI high density resistivity method and measures deep goaf by using EH4 Electromagnetic image system. As a result, it obtained distribution profiles of the goaf, divided key areas of abnormality and achieved satisfactory detection. At last it provides safety and security purposefully for the management of gob area.
