Discussion on Dust Control Technology of Coal Mine Integrated Excavation Face

Abstract

Coal is an important energy source in our country, and coal mine dust seriously endangers production safety and occupational health and safety, so it is necessary to take effective technical measures to prevent and control the coal mine. According to the main technical ways of dust prevention and control, the technical measures such as improving dust-proof water, strengthening coal seam water injection, carrying out high-pressure external spray, dust control and dust extraction purification, air flow purification and individual protection are discussed respectively. Finally, the technical measures of dust prevention and control in the future are prospected, and several technologies and equipment should be emphasized to break through.
