【摘要】 本文分析了山东省坊子煤矿19年来尘肺发生、发展情况.接尘工人4162名,现存尘肺病人51 1名,患病率为12.28%;其中,掘进工尘肺患病率是采煤工尘肺患病率的三倍. 尘肺发病平均工龄为20.65年,掘进工尘肺最短发病工龄5年,发病平均工龄12年;采煤工最短发病工龄11年,平均为24年. 尘肺进展:掘进工尘肺进展者较采煤工尘肺多,而且采煤工尘肺没有进展成为Ⅲ期的病例;进期时间采煤工较掘进工长一倍左右. 尘肺病人死亡年龄:掘进工尘肺死亡平均年龄50岁;采煤工尘肺死亡平均年龄68岁.更多还原

【Abstract】 The epidemiologic observations of pneumoconiosis in Fongtze coal mine from 1963 through 1981 was studied. The morbidity of pneumocon iosis among 4162 underground miners were 12.28% in which the rock-face miners were three times as many as the coal-face miners. The mean years of dust exposure in the initial pneumoconiosis patients was 20.65 years, but patients worked at rock-face was only 12 years and the patients worked at coal-face was 24 years. The duration of the pneumoconiosis patients worked at coal-face from first phase developed to second phase was much longer than the patients worked at rock-face. The relationship between dust properties and incidence. of pneumoconiosis was discused.更多还原
