摘　　要：为解决晋华宫矿工作面回采期间粉尘浓度过高的问题,在8218工作面采用动、静压混合注水降尘技术。通过现场监测、理论计算等方法,确定注水钻孔、注水工艺等参数,并在煤层注水前、后进行工作面粉尘浓度的监测。结果表明,注水后与注水前相比,总粉尘浓度平均降低率达58.69%,呼吸性粉尘浓度平均降低率达56.10%,有效地降低了工作面的粉尘浓度。In order to solve the problem of high dust concentration during mining in Jinhuagong Coal Mine, the water infusion technology for dust reduction by combining dynamic pressure and static pressure is adopted in the 8218 working face. Through on-site monitoring, theoretical calculation and other methods, parameters such as water infusion drilling and water infusion process are determined, and the dust concentration of the working face is monitored before and after infusion in the coal seam. The results show that the average reduction rate of total dust concentration is 58.69% and the average reduction rate of respirable dust concentration is 56.10%. The dust concentration of the working surface is successfully reduced.
