Advancements and Future Prospects of Dust Control Technology for Occupational Hazards in Metal Mining,Loading and Transportation in China
Among the main occupational disease hazards in metal mines,such as high temperature,noise,dust,toxic and harmful gases,dust caused pneumoconiosis accounts for the largest proportion of occupational disease cases.In order to contin-uously promote the research on occupational health protection of dust and ensure the safety of personnel,production and envi-ronment in metal mines,this study summarized the theory of dust source and diffusion in metal mines as well as the research status of dust occupational health and protection.Based on the systematic principle of safety engineering,it analyzed the techni-cal progress of dust occupational hazard prevention and control during mining,loading and transportation of metal mines in Chi-na from three dimensions:source control,process control and individual protection.On the basis of the above analysis,the paper analyzes the existing shortcomings and looks forward to the future development direction.It is believed that the existing defi-ciencies at this stage are that the theoretical system of metal mine dust control is not mature,the research on intelligent monito-ring and early warning technology of metal mine dust needs to be strengthened,the cross-cutting and collaborative research and application of different dust control technologies are weak,and the research and development of individual respiratory protection equipment oriented on the comfort of on-site personnel needs to be further strengthened.In the future,further work can be car-ried out from improving the theoretical system of dust control in metal mines,developing intelligent dust monitoring and early warning technology applicable to the dust production characteristics of metal mines,focusing on the cross line of dust control technology,collaborative research and application,and developing more ergonomic personal protection equipment.
