武钢大冶铁矿东露天采场系复合型(山坡、凹陷)露天矿。目前最大采深为264米,已全部进入凹陷露天作业。电铲装车过程中的扬尘是当前采场的主要尘源之一,不仅直接危害电铲司机的健康,而且严重污染采场大气。电铲司机室的粉尘浓度最高达100毫克/米~3,大大超过国家卫生标准。同时,采场夏季炎热,气温超过40℃,影响工人健康,自然减员十分严重,妨碍劳动生产率的
East open pit stope of the Daye Iron mine in WISCO compound type (hillside, depression) surface mine. At present, the maximum depth of 264 meters, has all been into the open pit operation. Dusting during the shovel loading process is one of the main dust sources in the stope. Not only does it directly endanger the health of shovel drivers, but also seriously pollutes the stope atmosphere. Shovel cab dust concentration of up to 100 mg / m ~ 3, greatly exceeded the national health standards. In the meantime, the stope is hot in summer and the temperature is over 40 ° C, affecting the health of workers. Natural skimming is very serious and hinders labor productivity
