摘要
以A矿深部运料车场巷道为背景,借助于有限元差分仿真软件FLAC3D,运用数值模拟手段,对不同侧压系数下的围岩偏应力场和塑性区分布规律进行计算分析,阐述了巷道周围不同部位岩体受力响应的差异性,以期研究结果为后续的巷道扩刷过程中支护方案的优化提供理论依据。
Taking deep transport materials roadway in A Coal Mine as the background, deviatoric stress field and plastic zone distribution law of surrounding rock under different lateral pressure coefficients were calculated and analyzed by means of numerical simulation with the help of finite difference simulation software FLAC3 D, and the difference of stress response of rock mass in different parts of roadway was expounded, which hoped that the research results can provide theoretical basis for the optimization of the support scheme in the process of follow-up brush enlargement.
