摘要
以陕西双龙煤业大巷的支护为工程背景,采用三维有限差分法数值计算程序FLAC3D对不同支护方案下巷道的变形破坏进行模拟,对模拟结果进行了分析,得出采动高应力区巷道围岩应力变化特征和运移规律。
Taking the support of Shaanxi Shuanglong Coal Industry as the project background,the paper simulated the deformation and failure in roadway under different support schemes with FLAC3D program,analyzed the results of simulation experiments,obtained the variation characteristics of stress and the rules of the roadway surrounding rock movement in high stress regions.
