摘　　要：济南章丘市多有小型滥采煤矿和黏土矿的采空区分布。拟建厂房在基坑底部发现多处回填采井后,先采用直流激电测深物探圈定采空塌陷范围,再进行钻探验证,基本查明了采空区的类型、规模和分布范围,指导了下一步注浆填充处理,可为类似采空区地基的工程建设提供一定参考。There are numerous small scale and unregulated abandoned coal and clay mineral mines in Zhangqiu City of Jinan. The backfill shafts were identified within the footprint of the proposed industrial building after the foundation excavation. The geophysical instigation using direct current induced polarization sounding was used to estimate the limits of the abandoned mine areas, The geophysical exploration results were verified by the conventional boring method. Based on the geophysical and geotechnical drilling results, the abandoned mining voids were compaction grout treated.
