地下金属矿山的充填采矿技术分析OA

There are many technical difficulties in the mining process of underground metal mines,such as complex geological conditions,narrow space,irregular working faces,etc.Traditional mining methods can cause significant damage to mines and the environment.Filling mining technology can effectively solve these problems.Compared with traditional mining methods,filling mining technology can effectively mix ore and filling materials evenly,improve the stability and bearing capacity of underground goaf,control and reduce ground subsidence,and has the advantages of short production cycle and high production efficiency.Based on the above background,this article focuses on the research of backfill mining technology for underground metal mines.Based on the analysis of the characteristics and mining difficulties of underground metal mines,a detailed analysis of backfill mining technology for bottom line metal mines is carried out using the stage empty field backfill method and the upward horizontal layered backfill method for scraper mining.
