摘　　要：本文针对屯兰矿8#煤层开采实践中底板承压水安全开采的问题,对8#煤层主要含水层含水性与隔水岩层阻水性能进行了分析,采用突水系数法,对8#煤底板突水危险性进行了计算与预测,对屯兰矿8#煤层的带压开采可行性进行了论证,认为在有效查明矿井存在的导水通道的基础上,并采取并予以采取相应措施,有效预防奥灰突水的发生,保证屯兰矿8#煤层安全高效开采。In this paper, aiming at the problem of safe mining of floor pressure water in the 8# coal seam mining practice of Tunlan Mine, the water content of the main aquifer in 8# coal seam and the water blocking performance of the water-retaining rock layer are analyzed. The water inrush coefficient method is adopted for 8# coal. The risk of water inrush from the floor was calculated and predicted. The feasibility of pressure mining in No. 8 coal seam of Tunlan Mine was demonstrated. It is considered that the effective guidance of the water channel in the mine is taken and corresponding measures are taken and taken. It can greatly prevent the occurrence of ash water and ensure the safe and efficient mining of 8# coal seam in Tunlan Mine.
