Research progress on coal mine dust hazard and its prevention and control technology
Coal mine dust not only affects the health of coal miners but also poses certain risks to the mining safety.The classification of coal mine dust was introduced,its hazards were analyzed,and the research progress of several most widely used coal dust removal and suppression technologies was reviewed,including coal seam water injection,spray dust suppression,chemical dust removal and foam dust suppression.Finally,based on the deficiencies of existing technologies,the development trends of coal mine dust prevention and control technologies were elaborated from the following three aspects:intelligentization and integration of dust removal equipment,precision of dust prevention and control technologies,and establishment of a smart dust removal system.
