摘要
针对赵官煤矿1705工作面为沿空留巷的具体情况,设计了膏体充填体与矸石带组成的不等强承载巷旁充填体,并建立了该充填体与以锚网带、锚索为支护材料的巷内支护系统相耦合的沿空巷道支护模型。通过数值模拟,研究了该类巷道的围岩应力和位移分布规律,为该类巷道围岩稳定性控制提供了依据。
For retaining roadway along gob in 1705 Mining Face of Zhaoguan Colliery,applying paste material and waste rock to composing roadway-side stowing body with un-equal strength,a supporting model for roadway retained along gob was set up.The model included stowing body and supporting system with anchored bolt,mesh and rope.By numerical simulation,stress and displacement of surrounding rock was researched.This provided reference for surrounding rock control of roadway retained along gob.
