西安机务段在给煤过程中,由于卸煤、装煤、整煤、机械抓吊、运煤的过程中而产生大量的煤尘,危害工人身体健康。过去认为,给煤是露天作业,而且煤尘浓度和隧道或煤矿开挖相比也低。因此对给煤工的煤肺预防,未予以足够重视。通过矽肺普查,发现从事给煤作业的工人胸片有明显尘肺改变。为了摸清给煤工煤肺发病情况,我们作了这次调查,现将有关资料小结报告如下: 一、劳动生产过程机务段给煤工,既是专职给机车上煤又是卸煤整煤的工种。在解放前,无机械设备,全靠人力作业,运来的煤下卸,卸后整理,用时用人力抬上煤台或机车上,煤尘较大,劳动强度亦大,因此吸入 During the process of coal feeding in Xi’an, due to coal unloading, coal loading, coal cutting, mechanical grasping hanging and coal transportation, large amounts of coal dust was generated during the coal supply process, endangering the health of workers. In the past, coal was exposed to open-air operations and coal dust concentrations were also lower than in tunnels or coal mines. Therefore, to coal miners to prevent coal, did not pay enough attention. Through the silicosis survey, it was found that there was a clear pneumoconiosis change in the chest radiographs of workers engaged in coal-feeding operations. In order to find out the situation of coal miners to coal workers, we made this survey, the relevant summary of the report are as follows: First, the labor production process section to coal workers, both full-time to the locomotive coal is coal unloading coal Type of work. Before the liberation, no machinery and equipment, rely entirely on human operations, shipped coal unloading, unloading and finishing, when used in manpower carried on the coal or locomotive, coal dust larger, labor-intensive, and therefore inhalation
