摘　　要：对小铁山矿上向巷道式胶结充填采矿法在充填体下底柱回采工艺进行系统的分析和研究。运用充填体的弹性力学理论,结合现场生产的现状,在安全的条件下,合理进行上向巷道式第一分层充填体的设计,解决困扰矿山充填体下底柱回采问题。the paper has conducted analysis and study on sill pillared stopping technology under the filling mass adopting the upwards laneway cemented stopping-filling mining. By applying elastic mechanics theory of the filling mass, with the present production situation on site, the upwards laneway on the first layer of filling body resonably under the condition of safe was designed. The design has resolved the problems that puzzled the mine. in sill pillared stopping under the filling mass.
