“自由呼吸”是每个尘肺病煤矿工人的渴望。为了达成矿工的心愿,雁崖矿党政工决定为井下一、二线的2000名员工免费检查尘肺病。多年来,由于在产煤、掘进生产过程中长期吸入煤尘、粉尘,在肺内滞留引起肺组织弥漫性纤维化,尘肺病矿工均有不同程度的胸闷、气短、呼吸困难等症状。 “Breathing freely” is the thirst for every pneumoconiosis coal miner. In order to reach the aspirations of the miners, the Party cadres at Yanyang Mine decided to inspect pneumoconiosis for 2,000 people in the first and second lines underground for free. Over the years, due to the long-term inhalation of coal dust and dust in the process of coal production and tunneling, the persistent lung fibrosis caused by retention in the lungs, pneumoconiosis miners have varying degrees of chest tightness, shortness of breath and breathing difficulties.
