:[目的 ]了解我区煤矿尘肺防治效果。 [方法 ]对甲、乙两个煤矿的尘肺病例 ,利用其本身提供的信息进行分析。[结果 ]采用湿式作业综合防尘的乙矿尘肺病例 ,发病高峰期推迟了约 14年 ,平均发病工龄延长了 9.19年 ,平均发病年龄延长了 13.18年 ,累计晋期率减少了 40 .2 0 %等。 [结论 ]采用湿式作业综合防尘取得了非常显著的效果。利用尘肺病例本身提供的信息 ,对发病工龄、年龄的长短、晋期率、死亡率等进行分析 ,能够适合于同一厂矿不同年代和不同厂矿尘肺防制效果的评价
: [Objective] To understand the effect of pneumoconiosis in coal mines in our district. [Method] The pneumoconiosis cases of two coal mines A and B were analyzed using the information provided by themselves. [Results] In the case of B pneumoconiosis with dust-free operation, the peak incidence of postponement of pneumoconiosis was delayed by about 14 years with an average length of service extended by 9.1.19 years. The average age of onset was extended by 13.18 years, with a cumulative reduction of 40.2% %Wait. [Conclusion] The comprehensive dust-proofing with wet work achieved very remarkable results. Using the information provided by the pneumoconiosis case itself, the analysis of the length of service, the length of age, the rate of Jin period, and the mortality rate can be suitable for the evaluation of the control effect of pneumoconiosis in different factories and mines in the same factory and mines
