摘　　要：目的分析恒源煤电公司和刘桥一矿2个矿井的综合防尘效果与工人尘肺发病情况,为制定预防措施提供依据。方法采用回顾性方法对1963年至2005年2矿历年所有接尘工人数和1963年1月至2005年12月2矿所有确诊尘肺病人数及2矿粉尘监测情况进行分析。结果2矿粉尘浓度差异具有显著性(P<0.05),粉尘分散度和游离二氧化硅含量差异无显著性(P>0.05),各年代恒源公司尘肺病人检出率均低于刘一矿,2矿差异具有显著性(P<0.05),Ⅰ期尘肺平均发病工龄恒源公司比刘一矿长,2矿差异具有显著性(P<0.05);1970年前各接尘年代的工人2矿尘肺病人检出率均无明显下降趋势,平均发病工龄亦无明显延长趋势。结论加强综合防治措施,加强工人自我防护意识,是控制尘肺发病的工作重点。Objective To Analyze general dustproof effect and pneumoconiosis morbidity situation of Hengyuan coal electricity company and Liuqiao mine and provide the basis for formulating preventive measure. Methods Retrospective review method was used to analyze numbers of worker exposed to dust and confirmed pneumoconiosis cases, and surveillance data of dust from 1963 to 2005 in the two ores. Results There was a significant difference of dust thickness between the two ores （ P 〈0.05 ）. There were no significant difference of dust disperse degree and content of free silicon dioxide between the two ores （ P 〉 0.05 ）. Detection rate of pneumoconiosis in Hengyuan coal electricity company was a lower than that in Liuqiao ore. There was a significant difference of pneumoconiosis between the two ores （ P 〈 0.05 ）. Average incidence length of service for I pneumoconiosis cases in Hengyuan coal electricity company was longer than that in Liuqiao ore. There was a significant difference of the incidence length of service between the two ores （P 〈 0. 05 ）. Before 1970, no obvious decreasing trend of pneumoconiosis detection rate was observed in the two ores and average incidence length of service of pneumoconiosis cases was not prolonged. Conclusion Enhancing integrated control measures, and strengthening the worker＇ s self - protection consciousness were the key to controlling pneumoconiosis morbidity.
