石人嶂钨矿1017例矽肺发病情况浅析

Preliminary analysis on 1017 cases of silicosis in Shi Ren Zhang tungsten mine.

本文对石人嶂钨矿1956～1988年确诊1017例矽肺发病情况进行了分析。结果发现,尘肺患者均系1958年前入矿开始接尘的工人,发病年龄轻(39.9岁),凿岩工最多(79.25%),接尘工龄较短(11.06年),肺结核并发率高(53.7%),死亡较工伤死亡高7.93倍。为了减少矽尘危害,作者强调搞好通风防尘工作外,对井下凿岩工、支柱工进行工种轮换制度是切实可行的。

The prevalence on 1017 cases of silicosis diagnosed from 1956 to 1988 in Shi Ren Zhang tungsten mine were analysed. Results showed that all patients suffered from silicosis were workers with dust exposure before 1958. Age for developing silicosis was rather young (average 39.9 years), Among the workers, rock drillers had the highest prevalence (79.25%). Years of dust exposure of the patients was rather short (averagely 11.06 years). The rate of pulmonary tuberculosis complication was rather high (53.7%). Mortality due to silicosis was 7.93 times higher than that due to industrial accidents. It was stressed that a sort of rotating working system for those workers of rock drilling and of prop setting would be desirable in addition to ventilation and dust control measures in order to minimize the silicon dust hazards.
