The application of sllow-hole shrinkage stoping of pit prop man-made bttom structure in Wuxu mine

The sllow-hole shrinkage stoping is the one of main mining method of Metal Mines in china. This paper introduced the application of Sllow-hole Shrinkage Stoping of Pit Prop Man-made Bttom Structure in Wuxu Antimony Mine. The Ore loss rate and mining cost could be significantly reduced and the overall efficiency of mine could be improved because using Pit Prop Man-made Bttom Structure at mining High-grade vein in small sized mines.
