摘　　要：杜家沟煤业由于煤层埋藏较浅,小煤窑进行了不同程度开采,形成了大片小窑采空破坏区,通过采用地面直流电四极测深技术对工作面2煤层赋存情况、小窑采空破坏情况进行探查,较为准确地圈定了井下小煤窑采空破坏区、煤层赋存区,为矿井采掘布置提供了精确的地质资料。In Dujiagou Coal Industry,because the coal seam is buried shallowly,the small coal kiln has been mined in varying degrees,forming a large goaf failure area of the small coal mine.By using the surface direct current quadrupole sounding technology to explore the occurrence of the 2coal seam in the working face and the goaf failure of the small kiln,the goaf failure area and the coal seam occurrence area of the underground small coal mine are delineated more accurately,which provides accurate geological data for the mining layout of the mine.
