摘　　要：为解决近距离空间交错巷道围岩控制及支护难题,结合交错巷道围岩物理力学性质,通过理论和数值模拟分析了空间交错巷道围岩应力分布特点,提出了“锚网索+U型棚+喷浆支护+注浆加固”的过上伏巷道联合支护方式。通过现场观测结果,该支护方式能有效控制交错巷道围岩变形,保证上下位巷道稳定性,为类似工程提供了借鉴意义。In order to solve the problem of surrounding rock control and support of the short-distance space staggered roadway,taking the engineering background of Jinyuan Mine's inner ring water bin penetrating the auxiliary haulage roadway in the first mining area as the engineering background,combining with the physical and mechanical properties of the surrounding rock of the staggered roadway,the stress distribution characteristics of the surrounding rock of the space staggered roadway are analyzed through theoretical and numerical simulation,and a combined support mode of"anchor mesh cable+U-shaped shed+shotcrete support"is proposed for the over-lying roadway.According to the field observation results,the support method can effectively control the surrounding rock deformation of the staggered roadway,ensure the stability of the upper and lower roadway,and provide a reference for similar projects.
