摘　　要：　华丰矿4号煤层冲击矿压灾害严重,随着采深的不断增大,这一问题更加突出。开采6号煤层保护层,将使4号煤层得到卸压,有利于减少冲击矿压发生几率。应用FLAC软件建立了相关数值模型,模拟分析了6号煤层开采的卸压效果;针对华丰矿地质条件,重点模拟分析了断层对6号煤层留设煤柱产生的应力集中影响,为华丰矿开采6号煤层提供了科学可靠的理论指导。The threaten of rock burst in seam No4 of Huafeng coal mine becomes more and more serious with the increasing of mining depthThe mining of seam No6 helps to decrease its probability of rock burstThe paper studies the reliving effect caused by the mining of seam No6 by means of FLAC numerical simulation with the emphasized analysis on the influence of coal pillars under the condition of faults,which provides a theoretical base for the scientific mining of seam No6
