在矽肺诊断工作中,我们发现硫磺矿矽肺与石工矽肺X线胸片各有其特殊改变,本文收集了硫磺矿矽肺50例,泸洲市建筑石工矽肺50例,现进行X线分析,提高对此类病例的认识,以利早期诊断。发病资料 (一)作业环境:硫磺生产接触矽尘者多为井下采矿,粉尘浓度最低21mg/m~3,最高307mg/m~3,矿石中游离二氧化矽含量10.47—20.49％,矿石中除硫外,还有铁铝等元素。石工系露天手工操作建筑石工,工人呼吸带的粉尘浓度为8.83—42mg/m~3,石料
In the silicosis diagnosis work, we found that sulfur mine silicosis and masonry silicosis X-ray have their own special changes. In this paper, 50 cases of silicosis of sulfur mine and 50 cases of silicosis of masonry in Luzhou City were collected. X-ray analysis Recognition of such cases to facilitate early diagnosis. (1) Operating Environment: Most people who make contact with silica dust from sulfur production are underground mining with the lowest dust concentration of 21mg / m ~ 3 and the highest 307mg / m ~ 3. The content of free silica in the ore is 10.47-20.49% Sulfur, there are iron and aluminum and other elements. Masonry open-air manual construction masonry, worker breathing belt dust concentration of 8.83-42mg / m ~ 3, stone
