潘集矿区位于淮南复向斜中的潘集背斜两翼。开采二叠系中、下石盒子组煤层,可采层数10～15层,总厚25～32米。本区为全隐蔽煤田,新生代巨厚松散堆积物,不整合覆盖于煤系地层之上,厚度为139～463米。它受古地貌形态控制,东南薄西北厚。按地层对比,划分为上、中、下三组含水层,通称1含、2含、3含。第三含水砂砾层(底砾层)直接与煤系地层接触,成为矿井充水 Panji Mining Area is located in the Huainan synclinator anticline Panji two wings. Mining Permian, the lower Shihezi coal seam, recoverable layers of 10 to 15 layers, the total thickness of 25 to 32 meters. The area is fully concealed coalfield, Cenozoic loose deposits of unconsolidated, unconformity over the coal strata above the thickness of 139 ~ 463 meters. It is controlled by the ancient topography, thin southeast thin. By stratigraphic contrast, divided into upper, middle and lower three aquifers, commonly known as 1 containing, 2 containing, 3 containing. The third water-bearing gravel layer (gravel layer) directly contact with the coal-bearing strata, as the mine water
