【摘要】 针对深部矿井开采中的巷道支护问题,根据黏弹性理论,在考虑开挖面空间效应的基础上,建立巷道围岩与支护体的耦合作用模型。通过算例分析了支护时间、支护体厚度等因素对巷道围岩稳定性的影响。更多还原

【Abstract】 In view of the roadway problems of underground mining on the soft rock roadway,based on the theory of viscoelasticity, a model of coupling action between rock and supporting body is built with considering the spatial effect of excavation face. The influences of the support time and the thickness of the supporting body on the deformation are analyzed.更多还原
