摘　　要：东瑞煤业综采工作面粉尘浓度较高,煤尘具有爆炸性,提出了应用注水降尘+红外线自动洒水降尘系统的治理方案。2101综采工作面应用效果表明:各处总尘浓度降低至55.2 mg/m^(3)以下,降尘率达87.2%以上,呼吸尘浓度降低至25.1 mg/m^(3)以下,降尘率达85.3%以上,粉尘治理效果显著。The dust concentration in fully mechanized mining face of Dongrui Coal Industry is high and the coal dust is explosive.The treatment scheme of using water injection dust reduction+infrared automatic sprinkler dust reduction system is put forward.The application effect of 2101 fully mechanized mining face shows that the total dust concentration everywhere is reduced to less than 55.2 mg/m^(3),the dust reduction rate is more than 87.2%,the respiratory dust concentration is reduced to less than 25.1 mg/m^(3),and the dust reduction rate is more than 85.3%.
