【摘要】 文章建立了煤矿深立井连接硐室群的三维数值计算模型,采用广义的Hoek-Brown准则估算了深部岩体的物理力学参数,将数值模拟分析得到的围岩破损区体积作为收益函数,基于硐室群实际施工条件约束和经济方面的考虑,运用动态规划理论,优选了深埋硐室群的最佳施工顺序,对煤矿类似复杂硐室群施工方案选择具有参考价值。更多还原

【Abstract】 Three-dimensional numerical model of chamber group connected with deep shaft in mine is established in this paper,and the mechanical parameters of the deep rock mass are estimated according to the generalized Hoek-Brown criterion.The volume of rock damage zone obtained by numerical simulation is used as the revenue function.In view of the construction constraints of chamber group connected with deep shaft in mine and economic factors,the optimal construction sequence of deep-buried chamber group is selected by dynamic programming method.The research results are valuable to the construction scheme selection of similar chamber group in mine.更多还原
