摘要 针对国投新集刘庄煤矿西区巷道埋深大、变形大和反复破坏等特点,在总结深部软岩巷道变形特点的基础上,深入探讨了深部软岩巷道的变形机理,提出了6大支护对策,并将研究成果应用到刘庄煤矿西区制冷硐室支护设计中。应用有限元数值方法,分析了巷道和支护结构的变形和受力特性,验证了文中提出的支护方法的可行性。 According of the characteristics of big burying depth,big deformation and repeating destruction in west roadways of Liuzhuang Coal Mine,based on study of supporting technology for deep-seated soft rock roadways,the deformation mechanism was analyzed and six measures were put forward.The study results were applied to for support design in the west refrigeration cavern of Liuzhuang Coal Mine,the deformation and mechanical characteristic of roadways were analyzed through the finite element numerical method,and the supporting technology was verified.
