目的浅析近8年开滦煤矿尘肺发病特点。方法对2005年1月1日-2012年12月31日开滦职业病防治所尘肺诊断组新诊尘肺患者的检出数、检出率、构成比、发病年龄、接尘工龄及接尘工种等方面进行调查。结果 8年来开滦煤矿共有46 091人受检,受检率28.52%(46 091/161 624),检出尘肺病人827例,尘肺检出率1.79%(827/46 091);2008年开滦尘肺病人检出率最高,2009年开滦尘肺病人检出率最低,2010、2011、2012年尘肺病人检出率趋于平稳,略有下降;尘肺病人平均发病工龄为(35.86±9.92)年,平均发病年龄(57.76±10.08)岁;主要接尘工种中,平均发病年龄以纯掘进工为最短,主掘进工与纯掘进工两者之间差异有统计学意义(P<0.05),主采煤工与纯采煤工之间差异有统计学意义(P<0.05);新发尘肺检出率以Ⅰ期煤工尘肺居多,占尘肺总数的94.56%(728/827);Ⅱ期占煤工尘肺总数的4.72%(39/827);Ⅲ期占煤工尘肺总数的0.72%(6/827),新发尘肺中Ⅰ期与Ⅱ期比较,Ⅰ期与Ⅲ期比较,Ⅱ期与Ⅲ期比较差异有统计学意义。结论近8年来开滦煤矿尘肺检出率1.79%,新发尘肺中以Ⅰ期轻症为主;尘肺平均发病年龄超过工人退休年龄;众多工种中发病以煤矿混合工最多,以纯掘进工的发病工龄最短,辅助工种发病人数有上升趋势。 Objective To analyze the characteristics of pneumoconiosis in Kailuan Coal Mine in recent 8 years. Methods From January 1, 2005 to December 31, 2012, the number of newly diagnosed pneumoconiosis patients in Kiln Pneumoconiosis Diagnostic Group, the detection rate, the constituent ratio, the age of onset, the age of exposure to dust, Investigation. Results A total of 46,091 people were interviewed at the Kailuan Coal Mine in the past eight years, with a rate of 28.52% (46 091/161 624), 827 cases of pneumoconiosis and 1.79% (827/46 091) of pneumoconiosis were detected. In 2008, Kailuan The detection rate of pneumoconiosis patients was the highest, the detection rate of pneumoconiosis patients was the lowest in 2009, the detection rate of pneumoconiosis patients in 2010, 2011 and 2012 tended to be stable and slightly decreased; the average length of service for pneumoconiosis patients was 35.86 ± 9.92 years, The average age of onset was (57.76 ± 10.08) years old. Among the main dust-pick workers, the average age of incidence was the lowest in pure digging and the difference between main and pure digging was statistically significant (P <0.05). The main coal mining The difference between workers and pure coal miners was statistically significant (P <0.05). The detection rate of newly diagnosed pneumoconiosis was mostly coal mine pneumoconiosis, accounting for 94.56% (728/827) of the total number of pneumoconiosis; The total number of pneumoconiosis was 4.72% (39/827). The stage Ⅲ accounted for 0.72% (6/827) of the total number of pneumoconiosis in coal miners. Compared with stage Ⅰ and stage Ⅱ, stage Ⅰ and Ⅲ, stage Ⅱ and Ⅲ The difference was statistically significant. Conclusions The detection rate of pneumoconiosis in Kailuan Coal Mine was 1.79% in the past eight years. The incidence of pneumoconiosis in newly diagnosed pneumoconiosis was mainly mild stage Ⅰ. The average age of pneumoconiosis exceeded the retirement age of workers. Among the many types of coal mine workers, The shortest length of service, the number of workers in the auxiliary type has an upward trend.
