针对大采高综采工作面粉尘产生量大的问题,对大采高综采工作面粉尘分布规律进行了研究.基于对大采高综采工作面粉尘产生机理及来源的分析,对赵庄煤矿5303大采高工作面粉尘浓度及分散度进行了实测,结果表明,5303大采高工作面粒径为2~5μm的粉尘所占比例最大,落煤、移架工序粉尘浓度最高,是粉尘防治的重点.“,”Based on large dust concentration in large mining height fully-mechanized face problem, the regularity of dust distributing of large mining height fully-mechanized face was studied. Based on the analysis of dust mechanism and source of large mining height fully-mechanized face, the dust concentration and dispersion of 5303 large mining height fully-mechanized face of Zhaozhuang Mine was measured, the results showed that diameter between 2μm and 5μm was the biggest percentage in 5303 large mining height, the process of coal and advancing support with the highest dust concentration were the key point of dust prevention and control.
