摘　　要：用FC-4型粉尘采样仪器对综采工作面在顺风割煤、逆风割煤、移架以及放顶煤四种不同工作条件下进行粉尘浓度测定,分析粉尘在不同工作条件下造成工作面污染的基本规律,得出采煤机割煤是工作面粉尘的第一大来源,最大粉尘浓度可达890mg/m3,移架是综采工作面粉尘的第二大来源,放煤的高度和次数对工作面的污染有很大影响。同时,指出采取综合的粉尘防治措施才是降低工作污染程度的最佳办法。Using FC-4 reparable coal dust sampling instruments equipment, measured the dust concentration in the mining face of fully mechanized under downwind, head winds cutting coal, Moving supporter and caving coal four different conditions. Analyzed the dust in different working conditions caused the fully mechanized mining face pollution basic rules. The results show that, shearer cutting coal is the Face first major dust source, the maximum concentration of dust 890mg/m^3 reached. Moving supporter is the fully mechanized coal face second-largest dust source. Caving coal height and frequency is making an impact on the mining face pollution. At the same time, indicating to adopt comprehensive dust control measures to reduce the pollution level is the best way.
