摘要
目的探讨鄂尔多斯市煤工尘肺发病情况,为进一步加强煤工尘肺防治和管理提供科学依据。方法选择从事煤炭行业一线作业工人,采用χ2检验、秩和检验分析不同接尘工龄、工种尘肺病发生情况。结果该市煤类行业2011年进行企业健康检查,资料完整的共9 230人,检出尘肺病61例,煤工尘肺发生率为0.66%;掘进工种煤工尘肺发生率(1.11%)明显高于采煤工(0.64%)和辅助工(0.10%),差异有统计学意义(P<0.05);接尘工龄≥30 a的煤工尘肺发生率最高,差异有统计学意义(P<0.05)。结论该市煤炭行业尘肺发生率较低,从事掘进工作和接尘工龄长的煤矿工人煤工尘肺发生率高。
[ Objective ] To understand the incidence of coal workers pneumoconiosis, and provide scientific evidence for reinforcing its prevention and management. [ Methods ] The coal workers in front-line production were selected for analysis of the incidence of pneumoconiosis between different service length and work types by χ2 test and rank sum test. [ Results] The health examination in coal industry began from 2011 in this city. The study showed 9 230 workers had integral data; 61 had pneumoconiosis; the inci- dence of coal workers＇pneumoconiosis was 0.66..% , that of tunneling workers wasl. 11% which was higher than eoal mining workers （ 0.64% ） and auxiliary workers （ 0.10% ）, with significantly difference （ P 〈 0.05） ; the incidence of coal workers＇pneumoeoniosis was highest in miners whose exposure years over 30a, with significant difference （ P 〈 0.05 ） . [ Conclusion ] The incidence of pneu- moeoniosis was low in coal industry of this city. The incidence of coal workers pneumoconiosis was the highest among those who have a long history of dust exposure and engaging in tunneling work.
