我们对澄潭江煤矿系统地查阅了该矿1971～1983年的接尘工人普查登记表和尘肺诊断结果登记卡,然后分类进行整理。历年尘肺患病情况如表1,历年共查出Ⅰ期55例、Ⅱ期38例、Ⅲ期2例,共计95例(包括1971年前9例)。 1981年发病率高达9.46％,其原因:(1)胸片质量较前提高,减少了漏诊;(2)这部分病人(70.59％)是60年代和60年代前八矿的老工人,小部分(29.41％)
We systematically consulted with the Chengtanjiang Coal Mine on the 1971 ~ 1983 dust census workers registration form and pneumoconiosis diagnostic results registration card, and then sorted for sorting. The prevalence of pneumoconiosis over the years is shown in Table 1. In the previous years, 55 cases were stage Ⅰ, 38 cases were stage Ⅱ and 2 cases were stage Ⅲ, a total of 95 cases (including 9 cases before 1971). The morbidity rate in 1981 was as high as 9.46%. The reasons were: (1) the quality of the chest radiographs was improved, which reduced the missed diagnosis; (2) This part of patients (70.59%) was the former workers in the former eight mines of the 1960s and 1960s, (29.41%)
