在煤炭生产过程小,以采掘工作面所生成的粉尘为最高,随着采掘机械化程度的不断提高,粉尘的生成量也将增大。我矿2102掘进工作面自使用一台 AM—50型奥地利掘进机组以来,产生粉尘量很大,空气中含尘量高达2000mg/m~3,虽然奥地利掘进机组附属有除尘装置,但体积大(长9365mm、宽1160mm、高1430mm);功率大(主电机100kw、付电机11kw,计111kw);需风量大(300m~3/min,实
In the coal production process is small, the dust generated by the mining face is the highest, with the increasing degree of mining mechanization, dust generation will also increase. Since the use of an AM-50-type Austria boring machine, mine 2102 heading face has produced a large amount of dust, the amount of dust in the air up to 2000mg / m ~ 3, although Austria excavation unit attached dust removal device, but bulky Long 9365mm, width 1160mm, height 1430mm); Power (main motor 100kw, pay 11kw motor, total 111kw); Need to air volume (300m ~ 3 / min,
