通过数值模拟计算,对巷道围岩应力分布及变形特征进行分析,同时提出支护方式。对于深部大变形、较破碎、巷道分叉处的巷道提出并设计了全封闭等应力可协调变形支护方式,对深井围岩变形机理和控制的研究具有积极意义。 Through the numerical simulation, the stress distribution and deformation characteristics of the surrounding rock are analyzed, and the supporting methods are proposed. For the large deep deformation and fragmentation, the roadway at the bifurcation of the roadway proposes and designs the totally enclosed and equal stress and can coordinate the deformation support method, which has positive significance to the research on the deformation mechanism and control of the deep surrounding rock.
