本文应用减寿年数和减寿率方法分析了煤矿尘肺患者１９７７～１９８６年回顾性定群调查死亡资料，并讨论了上述指标的优越性。结果表明，煤矿尘肺患者全死因标化减寿率为１０３．７９‰，是山东省城市男性居民的３倍，危害其健康的主要原因依次是恶性肿瘤、呼吸系病、心脏病和肺结核。掘进工尘肺患者肺结核、心脏病、、呼吸系病的寿命损失明显高于采煤工尘肺患者。减寿年数指标考虑了死者的死时年龄，可将人群健康所受危害的严重程度定量化。笔者认为减寿年数和减寿率可为明确重点防治对象提供科学依据，是衡量职业人群健康水平的较好定量指标。
In this paper, the data of retrospective cohort death in coal mine pneumoconiosis patients from 1977 to 1986 were analyzed by using the methods of life expectancy and life expectancy, and the superiority of the above indexes was discussed. The results showed that the standard of life-saving rate of all-cause mortality in coal mine patients with pneumoconiosis was 103.79 ‰, which was three times that of male urban residents in Shandong province. The main causes of their health were malignant tumor, respiratory disease, heart disease and tuberculosis. TBM pneumoconiosis patients suffering from tuberculosis, heart disease, respiratory disease life expectancy was significantly higher than coal mine workers pneumoconiosis. The indicator of life lost years takes into account the age at death of the deceased and quantifies the severity of the health of the population. I believe that the number of years of life expectancy and longevity can provide a clear basis for prevention and treatment targets to provide a scientific basis for the measurement of occupational health is a good quantitative indicators.
