煤工尘肺是慢性渐进性疾患,需粉尘在肺内长期积累才能发病,决定其转归的有三个重要因素是致病因素的质与量、病变发展过程与速度及是否合并其他疾病。不同质量的粉尘对人体产生的危害,在病变程度和进展速度亦有很大差异,本文对三个煤种八个煤矿尘肺发病工龄、进展年限、晋期率、观察年数、各期尘肺的构成及胸片X线表现等
Coal workers pneumoconiosis is a chronic progressive disease that requires long-term accumulation of dust in the lungs to attack, determine the outcome of the three important factors is the quality and quantity of pathogenic factors, the process of disease development and speed and whether other diseases. Different quality of dust on the human body hazards in the degree of disease and the rate of progress is also very different, this paper on the three coal-eight coal mine pneumoconiosis length of service, the length of life, the rate of Jin, the number of years of observation, the stages of pneumoconiosis And chest X-ray performance and so on
