摘　　要：文章以五龙煤业15号煤层奥灰水带压开采为背景,通过对15号煤底板隔水层、突水条件进行分析,得出15号煤层具备较好的带压开采条件,导水通道是否畅通是受水害威胁与否的决定性因素。根据地质资料计算得出15号煤层最大突水系数为0.066 MPa/m,局部存在突水的可能性,并根据带压开采危险程度对15号煤层划分了3个区域,制定了相应的防治水措施。研究结果为矿井15号煤层安全回采奠定了基础。In this paper,taking the No.15 coal seam under pressure mining of Wulong Coal Industry as the background,through the analysis of the No.15 coal floor water barrier and water inrush conditions,it is concluded that the No.15 coal seam has better mining conditions under pressure,and the flow passage is the decisive factor threatened by water disaster.According to the calculation of geological data,the maximum water inrush coefficient of the No.15 coal seam is 0.066 MPa/m,and there is a possibility of water inrush locally,and according to the dangerous degree of mining under pressure,it was divided in three areas,and corresponding water control measures are worked out.The research results lay a foundation for the safe mining of the No.15 coal seam in the mine.
