摘　　要：基于斯列萨列夫公式,以新安煤矿1煤采掘实际情况为例,进行了煤柱宽度、水头安全压力等计算,得出新安煤矿1煤层30 m煤柱可承受静水压3.73 MPa,1205采空区积水对1203工作面产生透水影响的最薄弱部位为1煤向上23 m裂隙带处等结论。经工程验证,该计算合理,能够满足安全生产的需要,为煤矿相邻工作面煤柱留设,老空水安全压力评价等提供了计算依据和工程实践,对类似矿井具有一定的借鉴意义。Based on the CπecapeB formula,taking the actual situation of No.1 Coal Mining in Xin′an Coal Mine as an example,this paper calculates the width of coal pillar and the safety pressure of water head.It is concluded that the 30 m coal pillar of No.1 Coal Seam in Xin′an Coal Mine can bear the hydrostatic pressure of 3.73 MPa,and the weakest part of 1203 working face affected by the accumulated water in 1205 goaf is the 23 m upward fracture zone of No.1 coal seam,It can meet the needs of safety production,provide calculation basis and engineering practice for coal pillar setting of adjacent working face and safety pressure evaluation of old empty water,and has certain reference significance for similar mines.
