摘要
本文根据大厂铜坑矿细脉带的工程地质条件 ,利用有限元分析了近百个不同采场尺寸情况下围岩和矿柱内的应力和位移的分布 ,根据各种不同的采场应力、位移的分布情况 ,提出相应的采场优化尺寸 。
In this paper, based on the geological condition in Dachang Tongking Tin Mine Stope, the stress and displacement distribution of the surrounding rock mass and mine pillar are analyzed by FEM under conditions of nearly a hundred different stope scales. As a result, the optimized stope size is given based on the different stress and displacement behavior. It can serve as a guide for the mine exploitation.
