陈申武等(铜陵有色金属公司职业病防治研究所)报道:为探讨以铜矿为主的金属矿山矽肺发生、发展的规律,特对本公司矿山工人进行了矽肺流行病学调查。其结果,矿山粉尘中,游离SiO_2含量在10％以下的占69％;粉尘分散度<5μ者占98％;历年粉尘合格率,1958—1966年间为21～
Chen Shenwu et al (Tongling Nonferrous Metals Company Institute of Occupational Disease Prevention) reported: In order to explore the copper mine-based metal mine occurrence and development of silicosis law, special mine workers in our company conducted a silicosis epidemiological survey. As a result, in the mine dust, the content of free SiO 2 is less than 10%, the dust dispersion degree is less than 5μ, accounting for 98%; the passing rate of dust over the years is 21 ~
