目的：调查煤矿从事粉尘作业人群肺结核发病情况。方法：对坊子煤矿的接尘人员进行肺结核普查，同时设对照组对比分析。结果：接尘组发病率３．５％，比对照组高８．３７ 倍（Ｐ＜０．０１）；掘进工和混合的发病率高于采煤工（Ｐ＜０．０１）；接尘组肺结核发病率随着尘肺病期的进展逐渐增高。结论：接尘人群仍是肺结核的易感人群；尘肺病越重肺结核合并率越高。
Objective: To investigate the incidence of pulmonary tuberculosis in dust mines in coal mines. Methods: Pulp coal mine dust collectors for tuberculosis screening, while the control group, comparative analysis. Results: The incidence of dusting group was 3.5%, which was 8.37 times higher than that of the control group (P <0.01). The incidence of burrowing workers and mixing was higher than coal mining workers (P <0.01) The incidence of pulmonary tuberculosis gradually increased with the progress of pneumoconiosis. Conclusion: The dust-exposed population is still a susceptible population of tuberculosis. The higher the prevalence of pulmonary tuberculosis in patients with pneumoconiosis.
