摘　　要：通过数值模拟分析技术对高应力软岩巷道在不同支护环境下的伸缩变形进行了模拟分析,结合四种支护方式的实际测量数据,通过对比分析提出:对于高应力软岩巷道通过预留或是主动在支架和围岩间形成间隔,形成一次支护在技术上是可行的,并且设计开发了针对秦源煤矿轨道石门的全断面锚网喷+锚索+圆形钢梁联合支护的施工工艺。According to numerical simulation analysis technology it gets simulation analysis on extension deformation of the high stress soft rock roadway in different supporting environment,combines with practical measurement data of four supporting ways,based on comparison and analysis provides that the high stress soft rock roadway according to reservation or active forming one time supporting on interval between supporting and rock surrounding is feasible in technology,and designs construction technology of whole section anchor ＋ anchor ＋ circular steel beam combination supporting aiming at coal mine track stone door in Qinyuan.
