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 investigate the incidence of coal worker’s pneumoconiosis in Erdos city and provide scientific evidence for further prevention and control of coal worker’s pneumoconiosis. Methods The workers engaged in front-line operations in the coal industry were selected. The chi-square test and rank-sum test were used to analyze the incidence of pneumoconiosis with different occupational ages and occupations. Results The city’s coal industry carried out enterprise health examination in 2011 with a total of 9,230 people, with 61 cases of pneumoconiosis detected. The incidence of pneumoconiosis was 0.66%. The incidence of pneumoconiosis was 1.11% The coal worker’s pneumoconiosis incidence rate was the highest in coal mining workers (0.64%) and auxiliary workers (0.10%) (P <0.05), and the difference was statistically significant (P <0.05 ). Conclusion The incidence of pneumoconiosis in the coal industry in the city is relatively low, and the incidence of coal worker’s pneumoconiosis in coal miners engaged in driving work and long-term dust collection work is high.
