"13th Five-Year Plan" coal mine dust occupational hazard prevention and control technology and development direction

In order to effectively prevent the occupational hazards of coal mine dust and improve the working environment of mines, from three aspects of dust control in mining face, dust control in other working places, dust continuous monitoring and pneumoconiosis warning, the latest development and practical application effects of the technology and equipment for the prevention and control of coal mine dust occupational hazards in China during the 13th Five-Year Plan period were discussed, such as comprehensive dust prevention and control in fully mechanized mining face with large mining height, long-pressure and short-drawn self-adaptive wind control and dust removal, continuous monitoring of respirable dust and early warning of pneumoconiosis. The deficiencies of the existing dust occupational hazard prevention technology and equipment were summarized and analyzed, and the development direction of the occupational hazard prevention and control technology for coal mine dust in China was prospected.
