摘要

随着能源开采由浅部向深部发展（>700 m），深部软岩巷道在高地应力下的变形破坏及其合理加固技术成为影响资源安全开采的重要因素。结合国投新集刘庄矿深部软岩及其软弱结构面的力学特性试验成果，提出软弱夹层的破坏准则及其损伤演化模型，并将其应用于含软弱夹层的深部软岩巷道围岩稳定性分析，研究不同支护方案下的围岩变形特性、破损区以及软弱夹层的离层和破坏情况，提出了合理的加固技术参数。

Abstract

As underground resources exploitation goes deeper and deeper

large deformation and failure of soft rock mass surrounding deep soft rock roadways

together with reasonable reinforcement techniques are main factors impacting safe and sustainable mining. Combined with results of indoor mechanical test on weak structural planes and soft rocks

damage criterion and damage evolution model of weak intercalated layers are established and applied to stability analysis of one deep soft rock roadway excavation of Huainan coalmine. Deformation characteristics

plastic zone of wall rock and failure zone of weak intercalated layers are studied; and reasonable reinforcement scheme is proposed. The achievements from the research can provide references to the design of supporting scheme of deep soft rock roadway.
