为了解某煤矿接尘工人肺通气功能损伤情况,探讨接尘对肺功能的影响,选取某煤矿采煤工299名作为观察组,另选取83名该矿非接尘工人作为对照组,统一进行肺通气功能各项指标测定。结果表明,排除吸烟因素后,接触煤尘能使肺通气功能异常率增高。提示,采煤工的肺功能明显低于对照组;工龄与肺功能指标有一定的相关性,接尘工人的肺通气功能随接尘工龄的增长而减低,接尘时间越长,工人的肺功能改变也就越明显,其肺功能损伤的程度也就越大。
In order to understand the damage of lung ventilation function of workers exposed to dust in a coal mine and explore the impact of dust exposure on lung function, select 299 coal mine workers in a coal mine as the observation group and 83 non-dust exposed workers in the mine as the control group Pulmonary ventilation function of the various indicators. The results show that, after excluding smoking factors, contact with coal dust can make pulmonary ventilation dysfunction rate increased. The results showed that the lung function of coal miners was significantly lower than that of the control group. There was a certain correlation between the length of service and the index of lung function. The lung ventilation function of workers exposed to dust decreased with the increase of the service life of dust. The more obvious changes in function, the greater the extent of damage to the lung function.
