Application and optimization research of backfill mining method in underground space development
In order to reduce the impact of mining operations,it is necessary to adjust and optimize the mining methods.Among them,filling mining method is one of many mining methods.Through the effective use of the mining method,it can reduce the destruction of the ecological environment,further reduce the resource input of the mining link,which can not only improve the safety factor of mining operations,but also bring greater economic benefits for mining enterprises,and is an important way for modern mining enterprises to achieve sustainable development.Because of the different geological conditions,mining technology and reserves of mines,mining enterprises have chosen different filling methods.In this paper,dry filling technology,sand filling technology and colloid filling technology are discussed.In the filling process,considering the differences of geological conditions,filling materials and bearing structures,combined with the demand for underground space utilization,the rational use of filling mining method enhances the function of filling mining method,gradually makes the filling mining method get a wider range of application,improves the mining efficiency of mineral resources,also ensures the safety of mining activities,and helps China's economic growth.
