Abstract: The dust hazard has become a prominent problem restricting the production safety，occupational health and environment of metal mines.Wet dust removal and bag dust removal techniques are adopted by the dust removal operations in most metal mines.Although the existing dust removal technique has higher dust removal efficiency，it still has the disadvantages of large resistance，high energy consumption and poor application effect.Therefore，the dust prevention and control technology of metal mines should be considered deeply.In order to further improve the mine operating environment quality， promote safe and clean production and occupational health，through systematic induction and summary of the domestic and foreign dust control technology in metal mines，the study status of the dust control technology and its applicable sites are analyzed comprehensively from six aspects of ventilated dust，closed dust control，spray dust removal dust suppressant，dust catcher and curtain separation dust.At the same time，the main problems of metal mine dust prevention and control technology at the present stage are pointed out，and the development directions of the dust control technology of metal mines are summarized emphatically.The study results show that significant progress has been made in the study of oocupational hazard control and dust control technology for metal mines in China.In the future，it should combine the characteristics of metal mine dust such as high dispersion，small particle size，high humidity and high concentration，and take high efficiency，low energy consumption，miniaturization and intelligence as the requirements to adopt a comprehensive dust-control technology means integrating effective dust control，atomization condensing，dust suppression and filtration and dust removal is adopted to achieve a breakthrough in the study and development of dust control and removal technology and equipment for effective risk control of fine dust in special environment space of metal mines，and provides theoretical and technical support for realizing scientific mining and accelerating green mine construction.
