三、机械化掘进工作面的除尘措施 随着煤炭工业机械化水平不断提高,机械化掘进工作面的除尘问题也越来越迫切和突出。机械化掘进工作面产生粉尘的主要因素是:切割岩体或煤体产生的粉尘,煤体下落或顶板冒落产生的粉尘,装运或转载产生的粉尘,机器运搬和支护清帮产生的粉尘,通风吹扬起来的粉尘。根据产尘的因素和尘源状况,机械化掘进工作面主要采用了以下一些除尘措施:
Third, mechanized mining face dust removal measures With the continuous improvement of the mechanization of the coal industry, mechanized mining face dust issues are more and more urgent and prominent. The main factors that lead to dust generation in mechanized tunneling are: dust produced by cutting rock mass or coal, dust generated by coal drop or roof caving, dust generated by shipping or reprinting, dust generated by machine transportation and support cleaning , Ventilation blowing dust. According to the factors of dust production and the status of dust sources, the mechanized excavation face mainly adopts the following dust removal measures:
