【摘要】 为了提高龙首矿深部采区综合生产能力及应用大规模采矿设备,选用不同的模拟方案,利用三维数值模拟的方法,结合龙首矿的实际情况,建立了八种三维实体模型,进行了龙首矿下向六角形大断面进路结构参数优化研究,分析计算了各种模拟方案的应力、位移及安全率的变化规律,最终确定了最优方案,为矿山进一步优化生产提供了理论依据。更多还原

【Abstract】 To enhance the comprehensive productivity of deep part zone and apply large-scale mining equipment in LONGSHOU mine,we choose the difference simulated scheme and use the method of three-dimensional numerical simulation.According to the actual condition of LONGSHOU mine,we optimized structural parameter by building eight kinds of three-dimensional entity model adopted the down hexagon drift.So we have obtained the optimum scheme by analysing the change law of safety factor,displacement and the stress of various simulated schemes,and offered the theory basis for further mining optimization production.更多还原
