摘　　要：该文分析了断层对煤层巷道弹性能分布的影响,结果表明,断层不仅影响到弹性比能的数值,而且影响到弹性比能的分布规律,巷道两帮煤体中的弹性比能最大值由巷道四角处转移到煤壁深处,可以积聚更大的能量,煤层弹性模量与抗压强度,对弹性能分布也有较大影响。That paper analyze the influence to elastic energy by fault. The results show that the mining depth effect not only numerical value but distribution of the elastic specific energy, and with the mining depth exceeding a certain limit, the max elastic specific energy accumulated in two sides roadway coal mass transferred from foursquare to deep coal face, which can accumulate more energy; the Elastic Modulus and compression strength have large effect on the distribution of elastic specific energy.
