目的 :探讨煤矿工人肺部损伤情况。方法 :对某煤矿 89例煤工尘肺和 46例井下接尘工人进行了肺功能测定和胸部X线检查并进行对比观察。结果 :煤工尘肺患者及井下接尘工人肺功能各指标均显著低于对照组 ;单纯煤工尘肺组肺功能损害以阻塞型为主 ,复合煤工尘肺肺功能损害以混合型为主。结论 :煤矿粉尘 (矽尘和煤尘 )均能对作业工人肺功能产生损害 ,其损害程度不同。
Objective: To investigate the lung injury of coal miners. Methods: A total of 89 coal workers’ pneumoconiosis and 46 underground workers exposed to dust were investigated for lung function and chest X-ray examination. Results: The indexes of lung function of coal workers with pneumoconiosis and workers exposed to dust were significantly lower than those of the control group. Pulmonary function impairment of coal miners with pneumoconiosis was mainly obstructive, while that of composite coal workers with pneumoconiosis was mixed. Conclusion: Coal mine dust (silica dust and coal dust) can damage the lung function of workers and their damage degree is different.
