Abstract
In recent years,the country has actively promoted underground backfill mining methods and introduced a series of safety and environmental protection laws and regulations to promote the promotion and application of backfill mining methods in mining.Due to the fact that the country can waive 50%of the resource tax on mineral resources extracted by filling methods that meet the conditions,priority should be given to filling mining methods before mining in newly built underground mines.Solid waste should be filled into the goaf as much as possible,forming a dense and sturdy filling object that has stable plasticity.On the one hand,it can maintain the stability of underground metal mine deposits,reduce safety hazards,and reduce the probability of accidents;On the other hand,it has better promoted the development and utilization of mining resources,which can maximize the utilization of mineral deposits.Based on this,this article conducts research on backfill mining technology in underground metal mines for reference.关键词
