搞好防尘是降低矽肺发病率的根本措施。本州某小铁矿近两年来作业环境粉尘的浓度大幅度回升,造成短期内矽肺病人成倍增长。我们对该铁矿进行了矽肺发病情况的调查,现将结果报导如下。该矿主要生产铁矿砂,工人多来自南充地区和本地的农村。全矿300余人,井下工人240人,年龄17～54岁,平均37.5岁,工龄2～25年,平均11.2年。该矿井下作业在1978～80年间以掘进基建为主,81年转入以采矿为主。 Improving dust prevention is the fundamental measure to reduce the incidence of silicosis. In the past two years, the concentration of working environment dust in a small iron ore mine in the state has risen sharply, causing the number of patients with silicosis to multiply in the short term. We conducted a survey on the incidence of silicosis in the iron mine, and the results are reported below. The mine mainly produces iron ore, mostly from Nanchong area and local workers in rural areas. All mine more than 300 people, 240 underground workers, aged 17 to 54 years, an average of 37.5 years of age, 2 to 25 years of work, with an average of 11.2 years. The underground operation in 1978 to 80 years to dig the infrastructural basis, 81 years into mining-based.
