Application of upward horizontal slice stoping and backfilling method in Hemushan Iron Mine

Mining method of sublevel open stoping with subsequent backfilling was used in Hemushan Iron Mine.Rock joints,poor stope stability and large ore loss occur during the mining of Houguanyinshan iron ore body.In order to ensure safety of mining,stability of ground pressure,and higher recovery rate,the upward horizontal slice stoping and backfilling method is recommended.Through comparison and analysis,it shows that the method is safe and reliable,and is more advanced in economic and technical indicators than that of mining method of sublevel open stoping with subsequent backfilling.
