中文摘要: 针对大屯锡矿进入深部开采后巷道围岩稳定性差的问题,为了保证矿山安全高效开采,本文采用数值模拟的方法分析了采场埋深、六边形矿房跨高比和侧压系数对围岩稳定性的影响。研究表明:(1)各影响因素对围岩的位移和应力均有影响,且各影响因素之间存在显著的交互作用;(2)采场埋深和侧压系数对采场围岩位移的影响较跨高比更加显著;(3)六边形矿房宽度大于高度时,两帮应力呈线性增长,跨高比对围岩应力的影响大于采场埋深和侧压系数。据此,当确定采场埋深和侧压系数后,改变六边形矿房的尺寸可以提高围岩的稳定性,研究结果对开采设计具有一定的参考价值。
Abstract:In view of the poor stability of roadway surrounding rock after deep mining in Datun Tin Mine, in order to ensure safe and efficient mining, in this paper, the effects of stope buried depth, hexagonal room span-height ratio and lateral pressure coefficient on surrounding rock stability are analyzed by numerical simulation. The research shows that : (1)Each influencing factor has an effect on the displacement and stress of the surrounding rock, and there is a significant interaction between the influencing factors ; (2)The influence of buried depth and lateral pressure coefficient on the displacement of surrounding rock is more significant than that of span-height ratio. (3)When the width of hexagonal room is greater than the height, the stress of two sides increases linearly, and the influence of span-depth ratio on surrounding rock stress is greater than the buried depth and lateral pressure coefficient. Accordingly, when the depth of the stope and the lateral pressure coefficient are determined, changing the size of the hexagonal chamber can improve the stability of the surrounding rock,The research results have certain reference value for mining design.
