摘要
针对武山铜矿北矿带钢筋混凝土下向进路式充填采矿法生产中普遍存在的充填不接顶现象，本文对充填程度与采场稳定性进行了数值模拟研究，为简化矿山充填工艺、降低成本．实施部分充填提供了理论依据。
Northern mine field of Wushan Copper Mine adopts underhand cut-and-fill mining in which vacant dimension exists widespread. Stope stability in different filling extent is studied with numerical analysis. This results in the concept of sectional filling which becomes the theoretical basis of adopting sectional filling method to simply filling craft and save filling cost.
