摘　　要：建立采场模型,经有限元数值模拟计算不同跨度值采场对应的采场顶板围岩应力、位移。通过主应力、正应力、位移等分析,在保证采矿生产安全的前提下,优化选取采场跨度,从而降低采准工程量、采矿损失率以提高采矿效率及效益。This paper establishes stope model, and calculates the corresponding surrounding rock stress on stope roof and displacement of different span value on the basis of finite element. On the premise that production safety of mining is ensured, selection of stope span is to be optimized to reduce mining quantity and mining loss rate so as to increase mining efficiency and benefit.
