探讨洛阳市某煤矿作业工人心肺功能异常的发生情况并进行煤尘的现场检测,为洛阳市的煤矿职业防护和职业健康教育提供依据。采用整群抽样的方法对洛阳市某煤矿井下作业工人735名和井上工人500名进行心脏、肺部的各项检查,同时进行煤尘的现场检测。结果显示,该煤矿井下作业工人高血压、心电图异常、肺通气功能损伤、肺部疾病的检出率均高于井上工人(P<0.05)。煤尘现场检测显示,井下总煤尘浓度的8 h时间加权平均浓度(TWA)高于国家标准,井上总煤尘浓度的8 h时间加权平均浓度(TWA)和超限倍数均低于国家标准,井上和井下煤尘分散度差异无统计学意义(P>0.05)。提示,该煤矿井下作业对作业工人的心肺危害高于井上工人,应对煤矿井下作业工人加强定期的健康检查和个人防护知识宣传,并通过采煤工艺的改进改善作业环境。
This paper discusses the occurrence of cardiopulmonary dysfunction in a coal mine worker in Luoyang City and carries out on-site testing of coal dust, which provides the basis for occupational protection and occupational health education in coal mine in Luoyang. A cluster sampling method was used to examine the heart and lungs of 735 workers and 500 underground workers in a coal mine in Luoyang City. At the same time, on-site testing of coal dust was carried out. The results showed that the workers in the coal mine had higher levels of hypertension, abnormal electrocardiogram, impairment of lung ventilation and detection of pulmonary diseases than those from the downhole workers (P <0.05). The on-site testing of coal dust showed that the 8-h time-weighted average concentration (TWA) of the total downhole coal dust concentration was higher than the national standard. The 8-h time-weighted average concentration (TWA) There was no significant difference in the dispersity of coal dust between uphole and downhole (P> 0.05). It is suggested that the coal mine underground work has a higher cardiopulmonary and pulmonary injury risk to workers than uphole workers. Coal mine workers should be encouraged to strengthen regular health examination and personal protection knowledge dissemination, and improve the working environment through the improvement of coal mining technology.
