Abstract: The engineering geologic properties of coal seam overburden red soil layer,basement rock of weathering zone or non-weathering zone in Yushen coal mining area are described in this paper.It is indicated that the red soil layer is of water-resisting property,but the basement rock of weathering zone has much more better water-resisting property due to its clay mineral content increasing.The Coal Seam No.2-2 is overburden by mid-hard rocks with many soft interlayers.The development height of caving zone during mining is relatively so lower,that it can not impact the Quatery age Salawusu Formation aquifers.Therefore,the engineering geologic conditions in this area are appropriate for coal mining under water-containing conditions.
