作者对现在很多国家(苏联、捷克、西德、美国、荷兰等)把煤尘中游离二氧化矽或灰分的含量作为煤尘所特有的危害标志提出了异议,认为粉尘的潜在危险主要不是石英的含量,而是煤的变质程度和腐殖酸、木炭、镜煤、无机杂质的含量以及它们的氧化程度。 作者研究了煤的致病作用与矿物成分和分散度组成的关系。对顿巴斯矿山七个联合企业10万工人体检的结果进行了分析,资料用标准程度的MuHck—22电子数字计算机进行统计处理。分析表明,与尘肺发病率有相关关系的是:工龄(r=0.341),昼夜平均采掘量(r=0.335),煤层平均变动厚度(r=0.212),特别是挥发物含量(r=0.644)。而与煤尘中
The author disagrees with the fact that many countries (the Soviet Union, the Czech Republic, the West Germany, the United States, the Netherlands, etc.) regard the content of free silica or ash in coal dust as a peculiar hazard sign of coal dust and believe that the potential danger of dust is not mainly quartz , But rather the degree of coal metamorphism and humic acid, charcoal, mirror coal, inorganic impurities and their degree of oxidation. The authors studied the relationship between the pathogenic role of coal and the composition of minerals and dispersity. The results of the physical examination of 100,000 workers at seven coal mines in the Donbas Mine were analyzed and the data were statistically processed using a standard MuHck-22 electronic digital computer. Analysis showed that the correlation between the incidence of pneumoconiosis and pneumoconiosis was as follows: length of service (r = 0.341), day and night averaged volume (r = 0.335), average thickness of coal seam (r = 0.212) . And with the dust
