本文通过对某火力发电厂２４８名接触低浓度煤尘的工人进行肺通气功能测定分析，发现即使接触低浓度煤尘，无论对男性还是女性，都可造成肺通气功能一定程度的损伤，ＶＣ值低于对照组（Ｐ＜００５）；接尘工人吸烟可使肺通气功能损伤程度加重，ＶＣ、ＦＶＣ、ＦＥＶ１及ＦＥＶ１／ＦＶＣ％值均低于对照组（Ｐ＜００５）。另外，接尘工人的肺通气功能损伤有随接尘工人工龄的延长而加重的趋势
Through analyzing the pulmonary ventilation function of 248 workers exposed to low concentration of coal dust in a coal-fired power plant, it was found that the lung ventilation function could be damaged to a certain extent even if the low-concentration coal dust was exposed. The VC value Lower than the control group (P <005); smoking workers exposed to dust can aggravate the degree of lung injury, VC, FVC, FEV1 and FEV1 / FVC% values were lower than the control group (P <005). In addition, the workers exposed to dust lung ventilation dysfunction with the extension of the length of service workers and aggravate the trend
