Optimization and application of the temporary cemented filling system in Hemushan Iron Mine

Upward-lane-filling mining method is used in Houguanyinshan Ore Block of Hemushan Iron Mine,and safe,efficient and timely filling to the mined-out area are the first premise of mining success.However,in the process of actual production in mines,mining production ability and filling ability can't match well,leading to mining capacity severely constrained.Therefore,considering the stope safety,production capacity,improving mining capacity and economic benefits,filling system is optimized,which gets a satisfied production and filling effect.
