摘　　要：小窑巷道的探查历来是工程施工的难点。由于小窑开采资料的不完整及管理的缺失,导致探查小窑巷道的成本大大增加,稍有不慎甚至会为上方承建的建筑物带来安全隐患。针对小窑巷道探查的难点,采用反磁通瞬变电磁法与地质雷达法相结合的综合物探方法,对某场地内塌陷区进行探查,通过综合物探的解译及建立三维地球物理模型,查明了小窑巷道的走向及埋深位置,并通过钻孔及孔内成像技术进行了验证,为后期场地采空区治理提供了依据。探测结果表明,综合物探方法对浅部小窑巷道的探查具有快速、高效的效果,对解决类似的地质灾害问题具有借鉴意义。The exploration of small mine roadway has always been a difficult point in engineering construction.Due to the incompleteness of mining data and the lack of management,the cost of exploring small mine roadway has greatly increased,and a little carelessness may even bury a great hidden danger for the buildings built above.In view of the difficulties in the exploration of the small mine roadway,a comprehensive geophysical exploration method combining the opposing coils transient electromagnetic method(OCTEM)and the ground penetrating radar method was used to explore the subsidence area in a certain site.Through the interpretation of comprehensive geophysical exploration and the establishment of a three-dimensional geophysical model,the trend and buried depth location of the small mine roadway were identified,drilling and in hole-forming imaging technology was verified,providing a basis for the later management of the goaf in the site.The detection results indicate that the comprehensive geophysical exploration method has a fast and efficient effect on the exploration of shallow small mine roadways,and has reference significance for solving similar geological hazard problems.
