淮南新区地形平坦,为隐蔽煤田,煤系露头被第四系冲积层覆盖,厚度为120～564m,其中砂层厚度占30～66％,含水丰富。老区浅部(-660m上)为现有矿井开采。煤系地层为二叠系,构造中等,煤层倾角新区一般10～15°,老区11～29°。有可采煤层
The surface of Huainan New Area is flat and is a concealed coal field. The outcrop of coal series is covered by Quaternary alluvium with a thickness of 120 ~ 564 m, of which sand thickness accounts for 30 ~ 66% and rich in water. The old shallow area (-660m above) for the existing mining. The coal-bearing strata are of Permian and medium in structure. The new coal seam dip angle is generally 10-15 ° and the old area is 11-29 °. Coal mining is possible
