电铲在铲装过程中,使周围空气产生大量粉尘,浓度高达几十到几百(毫克/米~3)。司机室内粉尘浓度也超过国家标准,对三个司机室20次测定,平均粉尘浓度为9.3(毫克/米~3),最高达37.8(毫克/米~3)。 1973年6月以来,本钢、南芬露天矿、劳动卫生研究所、钢铁研究所和东北工学院等单位的工人、干部、工程技术人员、医务人员和教师组成了三结合防尘试验小组,并试验成功电铲司机室空气净化除尘装置,室内粉尘浓度达到了国家标准,效
Shovel shovel in the process of installation, the surrounding air to produce large amounts of dust, the concentration of up to tens to hundreds (mg / m ~ 3). The driver’s indoor dust concentration also exceeded the national standard, and the three cabs were measured 20 times with an average dust concentration of 9.3 (mg / m ~ 3) and a maximum of 37.8 (mg / m ~ 3). Since June 1973, workers, cadres, engineers and technicians, medical staff and teachers from units such as Benxi Iron and Steel, Nanfen Open-pit Mine, Institute of Labor Health, Steel Research Institute and Northeast Institute of Technology have formed a three- And test the successful shovel cab air purification dust removal device, indoor dust concentration reached the national standard, efficiency
