为了解冶金基本建设工人尘肺发病情况,给防治工作提供依据,对某冶金建设公司接尘作业工人进行了调查。 冶金基建工人在进行基建作业时多方面接触粉尘。矿山基建的凿岩爆破;铸钢、铸铁时的清砂作业,空气中的粉尘浓度平均可达161.8毫克/立方米左右;筑炉作业使用耐火材料(平均粉尘浓度达633.4毫克/立方米,游离二氧化矽为35.7％;混凝土预制构件制作,混凝土基础作业和水泥搅拌,运输
In order to understand the incidence of pneumoconiosis in basic construction workers in metallurgy and provide basis for prevention and treatment work, a survey was conducted on dust-pickings workers of a metallurgical construction company. Metallurgical infrastructure workers are exposed to dust in many aspects during infrastructure operations. Mining infrastructure drilling blasting; sand castings, cast iron, dust concentration in the air up to an average of 161.8 mg / cubic meters; building operations using refractory materials (average dust concentration of 633.4 mg / cubic meter, free Silicon dioxide 35.7%; concrete prefabricated parts production, concrete foundation work and cement mixing, transportation
