煤显微组分组成对配煤镜质体反射率分布的影响

为了探究煤显微组分组成对配煤镜质体反射率分布的影响,本研究建立了基于配合单煤镜质体反射率分布、镜质组含量及配入比例的配煤镜质体反射率分布的预测方法,同时以开滦矿区4种不同变质程度烟煤（R_o,ran介于0.88%~1.30%)为研究对象,利用软件Design-Expert 8.0进行配煤镜质体反射率分布影响因素及其显著性分析。三因素显著性分析结果表明,相比于镜质组含量和配入比例,参与配煤的单煤镜质体反射率是影响配煤镜质体反射率分布的显著性因素;当各配合单煤镜质体反射率确定时,两因素显著性分析结果表明,镜质组含量和配入比例均是影响配煤镜质体反射率分布的显著性因素。

Effects of maceral composition on vitrinite reflectance distribution of blended coals

In order to investigate the effects of maceral composition on vitrinite reflectance distribution of blended coals,this paper established the technique of predicting vitrinite reflectance distribution of blended coals in terms of vitrinite reflectance distribution of single blending coal,vitrinite content and blending ratio,and the influencing factors and their significant analysis of vitrinite reflectance distribution of blended coals using Software Design-Expert 8.0 were performed based on four coals with vitrinite reflectance (R_o,ran) varying from 0.88% to 1.30% in Kailuan coalfield. Results of the significant analysis with three factors show that compared to vitrinite content and blending ratio,the vitrinite reflectance of single blending coal is a significant factor influencing vitrinite reflectance distribution of blended coal;when vitrinite reflectance distribution of single blending coal is fixed,results of the significant analysis with two factors show that both vitrinite content and blending ratio affect the vitrinite reflectance distribution significantly.
