本文采用去死因寿命表方法及去死因后ｆｕｌｆｉｌｌｍｅｎｔ指标，对某钨矿矽肺病例（ｎ＝１０４１，其中死亡５０３例）进行分析，研究不同死因对钨矿矽肺寿命的影响。结果显示：因肺结核死亡使钨矿矽肺诊后的期望寿命减少１０．３８岁，不死于肺结核能使矽肺诊后的期望寿命增加６６．８０％，矽肺诊后各观察时间去肺结核死因后ｆｕｌｆｉｌｌｍｅｎｔ指数均较大，尤以初诊阶段更突出，肺结核死因为耗损钨矿矽肺寿命的第１位原因；耗损钨矿矽肺寿命的第２～５位死因依次为尘肺、气胸、各种肿瘤、各种肺炎。提示钨矿矽肺第三级预防的重点首为防制矽肺结核，次为控制矽肺进展恶化。 In this paper, we use the method of death due to life table and the fulfillment index after death to analyze the influence of different causes of death on the silicosis life of tungsten ore in silicosis cases (n = 1041, 503 cases of death). The results showed that the life expectancy after silicosis died of tuberculosis was reduced by 10.38 years due to tuberculosis death, the life expectancy after silicosis without death increased by 66.80%. After silicosis, the fulfillment index Especially in the newly diagnosed stage. The death of tuberculosis was the first reason that depleted the life of silicosis in tungsten mine. The causes of death in silicosis of tungsten mine were ranked as pneumoconiosis, pneumothorax, various tumors, pneumonia . Tip tungsten silicosis third priority prevention focus on the prevention of silicosis tuberculosis, times to control the progression of silicosis worse.
