摘　　要：针对呼吸性粉尘对矿井工人身体健康的危害,对煤矿综采工作面、综掘工作面、炮掘工作面等进行分工种个体性的全尘和呼尘监测,测定了各工作面粉尘(全尘和呼尘)的浓度、粉尘分散度和SiO2浓度。其结果表明:全工班呼吸性粉尘测定的方法更加真实可靠,更真实地反映了呼吸性粉尘对井下各操作工种的致病危害,测得的各工作面各工种的呼尘浓度均高于国家标准。通过数据的分析以及工人的建议,提出了一些新式的、有效的防尘措施来降低呼吸性粉尘对人体健康的危害。Dust and aspiratory dust were monitored personally on the full-mechanized mining work face, full-mechanized tunneling work face and gun tunneling work face in the coal mine to investigate the harm of aspiratory dust to the workers underground. Dust concentration, size distribution and SiO2 concentration were mensurated, which was beyond the national standard. The result indicates that this mensuration of respiratory dust in work groups is more reliable and credible, and the data obtained by this means factually reflects the harm of respiratory dust to miners. Finally, according to the statistic analysis of data and the advice from miners, some new and effective methods were proposed so as to reduce the harm of aspiratory dust to miners＂ health.
