应用三维有限单元法对鹤庆锰业集团公司小天井矿区上向进路分层干式充填采矿过程进行了不同开挖方案的模拟分析，所优选的开挖方案对矿山安全生产起到较大作用，模拟结果与生产实际基本一致。
Three-dimensional finite element method was used to simulate and analyze different excavation schemes in the process of stratified dry-filling mining in the small pavement mining area of Heqing Manganese Industry Group Corporation. The optimal excavation scheme has a great effect on mine safety production Role, the simulation results and the actual production is basically the same.
