摘　　要：开磷集团马路坪矿采用分段空场法嗣后充填法开采,为确保矿区在施工期及运营期的安全性,对采场顶板中部部位采用预应力锚索加固支护。通过采场支护前后的位移与变形特征、最大主应力分布特征、塑性区分布特征对比分析结果,分析了采场的稳定性,验证了支护方式的科学性。The Maluping mine of Kailin Group takes the sublevel field subsequent filling method to mine ore,and it can ensure the security of the mining area during the construction and operation.Maluping mine employ supporting anchoring in the central part of the stope roof.The displacement and deformation characteristics of supporting the stope before and after、 the maximum principal stress distribution and the distribution characteristics of plastic zone were analyzed and the analysis of the stability of stope were carried out,then we demonstrate the scientific support patterns.
