摘　　要：确定合理的采场参数是矿山进行安全、高效生产的前提。本文采用边界元方法对垂直分条充填采矿法采场稳定性进行数值分析。根据矿体开采条件 ,建立开采模型 ,进行采场矿岩及充填体应力、应变特性的分析 ,确定了合理的矿房、矿柱宽度。It is essential to determine suitable parameters of a stope for efficient mining The stope stability of stoping and filling with transverse strips is analyzed with Boundary Elements Method in this article Analysis on the distribution of stress and strain in the rock around stopes is done with mining models on the basis of various mining conditions The stope parameters,such as stope span,fill height and pillar width,and mining sequence are properly determined based on the results of numerical anslysis
