Abstract: Dust pollution in metal mines has always affected the physical and mental health of field workers.In order to further improve the dust pollution control technology in metal mines，meet the higher level requirements of dust control，and ensure the safety of front-line operators and mechanical equipment，the status quo of dust hazards in metal mines and the development of control technology in recent years are reviewed.The development and main dust sources of occupation diseases in metal mines since 2001 were analyzed comprehensively.Principle and working principle of dust removal，spray dust suppression， foam and dust suppression agent in dust control technology were analyzed.The analysis shows that the dust control technology in metal mines is not perfect at this stage，which mainly shows that the physical and chemical properties of dust are not clear，the intelligence of dust removal equipment is poor，the dust removal system is not perfect，and the dust removal method is not environmental protection. In view of the problems existing in the research on dust pollution control technology in typical workplaces，the development directions of dust pollution control technology in metal mines are proposed in four aspects，including the establishment of dust physical and chemical property database of metal mines，the construction of mechanized，automatic and intelligent joint dust control system，the research and development of new equipment for dust prevention and control，and the development of efficient，environmentally friendly and economic water cannon mud and dust suppressor effective control of dust pollution.
