该矿建于1969年,井下作业接尘工人约800余人,设备简陋,作业环境煤尘浓度最低1.25mg/m~3,最高达63mg/m~3;岩尘和混合粉尘也都超过规定允许的浓度。1977年曾在体检中发现尘肺4例。以后10余年中曾多次体检,但均未再有尘肺病例发现。1989年4月,我们对该矿的尘肺发病情况进行调查,结果按“GB5906-86尘肺X线诊断标准”,确诊新尘肺病例44例。这一结果表明,自1977年以来的多次体检中,均有尘肺漏诊现象发生。造成漏诊的主要原因有:1.漏检一些工人缺乏卫生知识,对粉尘危害及健康监护认识不足,对体检持消极态度,不去接受体检。
The mine was built in 1969 and there are about 800 miners working in the mine downhole. The equipment is primitive and the concentration of coal dust in the working environment is the lowest 1.25mg / m ~ 3, up to 63mg / m ~ 3; rock dust and mixed dust also exceed the allowable concentration. In 1977, pneumoconiosis was found in physical examination in 4 cases. After more than 10 years of physical examination, but no case of pneumoconiosis were found. In April 1989, we investigated the incidence of pneumoconiosis in the mine. According to the “GB5906-86 diagnostic criteria for pneumoconiosis”, 44 new pneumoconiosis cases were diagnosed. This result indicates that pneumoconiosis has been missed in multiple medical examinations since 1977. The main reasons for the missed diagnosis are as follows: 1. Missing Inspection Some workers lack health knowledge, lack awareness of dust hazards and health guardianship, and have a negative attitude towards physical examination and do not undergo physical examinations.
