摘要
利用基于有限元基本理论的数值模拟方法,采用极限分析方法分析护顶层的力学稳定性,确定了进路跨度与护顶矿层厚度的关系,推荐超前注浆造顶上向进路尾砂充填连续采矿法回采方案。
Based on the finite element numerical simulation method, this paper used the limit analysis method to analyse the mechanical stability of top leaf and confirmed the relation of route span and top ore thickness. The advanced grouting upward continuous draft-filling stoping was recommended.
