摘　　要：通过煤矿围岩变形特征的数值模拟分析,建立有限元模型,给出巷道围岩的变形特点和应力分布。通过综合支护方案的研究,控制顶板和底板的变形和应力状态,进一步给出了支护的优化建议,为煤矿巷道的支护加固研究提供技术经验。Based on numerical simulation analysis of deformation charactem of surrounding rock in coal mine, finite elementmodel was built and deformation characters and stress distribution of surrounding rock were put forward. Through analysisof comprehensive supporting scheme, deformation and stress state of roof and floor were controlled, which then providedoptimization suggestions of timbering and technical experience to study on support and reinforcement of coal mine tunnel.
