Experimental Study on the Effect of Filling Mining Method in Changgou Manganese Mine
Based on the mining area,mining depth and ore types of Changgou Manganese Mine,this paper elaborates in detail on the geological conditions,mining methods and mining processes of the filling mining trial area.The technical requirements for mining roadway operations were explained,including excavation direction,roadway specifications.The stability of the backfilling mining method was analyzed through numerical simulation,and it was concluded that using backfill mining can reduce waste rock emissions to save costs and improve production efficiency.It has created reliable safe production conditions for the next step of deep mining,and provides a certain degree of safety guarantee for the maximum recovery of deep mining resources.
