摘　　要：为确保43101巷道过断层破碎带区域的支护效果,先采用瑞利波探测仪超前探测掘进巷道可能遇到的地质构造,再对巷道煤岩体物理力学参数进行测试,并通过数值模拟分析断层破碎带应力场分布特征;拟定巷道正常区域和断层破碎带区域的支护方案;应用支护方案后,结果表明,3条断层破碎带区域巷道变形量均不大,支护方案能够有效控制巷道断层破碎区域的围岩变形。To guarantee the support effect in crossing fault fracture zone at 43101 roadwy,the author proposes the support scheme in normal zone and fault fracture zone through detecting the geological structure in advanced excavating roadway by Rayleigh wave detector,testing the physical mechanical parameter of coal-rock mass and analyzing the stress filed distribution characteristics of fault fracture zone by numerical simulation,whose application results show that it can effectively control the surrounding rock deformation with small deformation in three roadways of fault fracture zone.
