摘要
从煤显微组分方面对不同煤化程度的22种煤样进行了CO的扩散试验及煤显微组分的鉴定。通过分析试验可知,中低变质程度的烟煤中镜质组含量相对惰质组含量较高;对数据进行关联分析发现CO扩散量与煤中镜质组含量成正比关系,与惰质组含量成二次曲线关系。从惰质组与镜质组之比对CO扩散量的影响分析可得出,惰质组对CO的扩散的影响大于镜质组对CO的影响,并用QM(Quantum Mechanics)软件对试验数据进行了分析处理,为进一步研究CO在煤层中的扩散机理提供了理论基础。
From the coal maceral, the CO diffusion and coal maceral experiments were conducted on 22 coal samples with different degree coal metamorphism. The experiment showed that the vitrinite content of the bituminous coal with medium and low degeneration degree would be higher than the inertinite content. The related analysis of the data showed that the CO diffusion quantity would have the direct ratio relationship to the vitrinite content of the coal and have the second curve relationship to the inertinite content. From the comparison between the vitrinite and inertinite, the influence analysis on the diffusion quantity could be obtained. And the inertinite influenced to the CO diffusion would be lager than the vitrinite to CO. The Quantum Mechanics software was applied to analyze and process the test data in order to provide the theoretical foundation to further study the diffusion mechanism of CO in seam.
