摘　　要：随着经济和社会发展,城市规模不断扩大,之前的偏远矿区一步步进入城市发展范围内,采空区的存在给城市建设和人民的生命财产安全造成了巨大隐患,因此对城市及周边采空区开展勘查工作具有极其重要的现实意义。本文讨论了航空磁测、高密度电法、小线框大电流瞬变电磁三种方法相结合在济南东部城市交通项目小龙堂矿区中的应用效果,并结合钻孔资料推断了采空区分布特征,取得了较好的地质效果,为后期治理提供了可靠的地球物理依据。With the development of economy and society, the scale of the city continues to expand, the previous remote mining area goes into the scope of urban development step by step, the existence of goaf brings huge hidden danger to urban construction and the safety of people’s lives and property, so it has extremely important practical significance to carry out exploration work around city and its surrounding goafs. In this paper, authors discussed the application effect of the combination of aerial magnetic survey, high-density electrical method and small wireframe large current transient electromagnetic method in Xiaolongtang mining area of urban transportation project in east of Jinan, and inferred the distribution characteristics of goaf based on the borehole data, which has achieved good geological effects and provides a reliable geophysical basis for the later treatment.
