摘　　要：本文对驻马店新安店采石厂126名粉尘作业工人及180名对照组症状体征进行比较分析及粉尘作业工人的胸片X线形态分析。采石厂最大粉尘浓度超过国家标准277．15倍，尘肺病发病率10．32％，且有1例速发型矽肺。粉尘作业工人咳嗽、咳痰、气短、肺罗音、鼻腔阳性体征的发病率均显著高于对照组，X线形态改变基本符合尘肺病的病理发生过程。结果表明：采石厂高浓度的粉尘对粉尘作业工人的呼吸系统危害极大，应积极采取措施以预防为主。In this report, 126 persons under the dusty circumustances form XinAnDian stone factory in contrast to 180 healthful persons were observed. By analysing their cymptoms and sign and chest xeroradiograph, we find that the morbidity of the pneumoconiosis is 10. 32%, moreover there is a im mediate silicosis when dust concentration is 277.15 as times as country standard. The incidence rate of the miner's clinical manifestation such as ough, expectoration, short breath, vesicular rale and nasal cavity positive sign is dramatic higher than control group. Xray morphology is coincident with the pathologic chang of the pneumoconiosis. The result show that the high concentration dust is seriously hazard to respiratory system of the miners. To prevent pneumoconiosis, we should adopt the active measure.
