近几年来,我们在煤矽肺诊断工作中,遇到少数病例的病变先从上肺野出现。国家现行矽肺诊断分期标准对此类病例未提及。我们在反复阅读湖南省湘永煤矿历年来诊断的煤矽肺胸片中,选择此类资料29例进行分析,借以提高对此类病例的认识,达到早期诊断的目的,并探索其发病特点与诊断分期标准,以指导实践。发病资料分析1.工种:29例中掘进工16例,采掘混合工10例,钉道工2例,开拓掘进的水泵工1例。钉道工与水泵工,都是跟随掘进工进行工作。以上这些工种,均系以接触游离二氧化矽含量较高的粉尘为主。由于这些工种也要接触煤尘(如开凿半煤岩巷道或全煤巷等),因此他们所罹患的尘肺,仍属煤矽肺。
In recent years, we have encountered a few cases of pathological changes in the lung from the lung field in the diagnosis of coal silicosis. The current national silicosis staging standards do not mention such cases. We repeatedly read the Hunan Yong mine over the years diagnosed coal silicosis chest X-ray, select 29 such cases of such data for analysis in order to raise awareness of such cases, to achieve the purpose of early diagnosis and to explore the characteristics and diagnosis of its onset Staging standards to guide practice. Analysis of incidence data 1 types of work: 29 cases of digging workers in 16 cases, mining mixed workers in 10 cases, Pinao workers in 2 cases, pioneering water pump work in 1 case. Dingdao workers and pump workers, are to follow the excavators work. These types of work, are to contact the Department of higher free silica content of dust-based. As these types of work also come into contact with coal dust (such as excavation of semi-coal rock roadway or full coal lane, etc.), the pneumoconiosis they suffer is still coal silicosis.
