Numerical Study on The Protective Mining in Seam No.6 of Huafeng Cial Mine

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
