摘　　要：文章基于某煤矿煤层疏松易碎特点,以己15—21070综采工作面为研究对象,采用数值模拟与现场分析,研究了综采工作面煤尘运动规律:采煤机割煤时下风向20~30 m范围内的煤尘浓度最大;而移架时煤尘浓度距移架处10~20 m范围内最大;对采煤机,液压支架喷雾进行改进,同时采用浅孔动压注水防治措施。Based on the characteristics of a coal seam loose and fragile,taking 15-21070 fully mechanized mining face as the research object,the law of coal dust movement in a fully mechanized coal mining face was studied by numerical simulation and on-site analysis：The maximum concentration of coal dust in the range;while the coal dust concentration when moving from the rack at a maximum range of 10-20 m;improve the shearer,hydraulic support spray,while using shallow hole hydrostatic pressure water prevention and control measures.
