30多年来,我国矿山的防尘技术有了很大的发展,大幅度地降低了矽(尘)肺病的发病率,取得了显著的效果。但是,发展很不平衡,化学矿山至今仍然存在三高(矽肺发病率高、重症病率高和死亡率高)和三低(粉尘浓度合格率低、用于通风防尘的经费少和个体防护用品使用率低)的现象。据1983年对五个重点矿山的抽样调查,1963～1982年查出的各期矽肺病患者,占接尘人数
Over the past 30 years, dustproof technology has been greatly developed in our mines, drastically reducing the incidence of silicon (dust) lung disease and achieving remarkable results. However, the development is very uneven. There are still three high levels of chemical mines (high incidence of silicosis, high incidence of severe diseases and high mortality) and low levels of three (the qualified rate of dust concentration is low, the funds for ventilation and dust prevention are few and the individual protection The use of supplies is low) phenomenon. According to a sample survey of five key mines in 1983, patients with various stages of silicosis who were diagnosed between 1963 and 1982 accounted for the largest number of dust-catching persons
