煤中49种元素含量与煤岩组分和煤化程度的相关规律

Correlation of Coal Constituents and Coalification Degree versus Contents 49 Kinds of Elements in Coal of China

应用中子活化分析等方法,对我国不同地区和不同时代的30个有代表性煤样中的49种元素做了系统测试,同时,对每一个煤样进行了显微煤岩组分和反射率测定。在此基础上,通过回归分析和相关模拟,揭示出煤中49种元素与显微组分、矿物成分和煤化程度的相关规律。这些规律对勘查和合理利用煤的伴生矿产资源,对预测煤中有害元素的洗选性和迁移扩散均有重要的理论和实际指导意义。

Forty nine kinds of elements in thirty coal samples representative of various ages and fields all over the China are analyzed by means of INAA, XRF, AA, ICP, etc. Maceral and mineral analysis and reflectance measurements are carried out on each sample. After regression and correlaton analysis the relationship among elements and macerales, minerals and Rr(%) of vitrinite in oil are revealed. These regularities would play an important role in following two aspects: 1. exploring and utilizing the associated mineral resources; 2. prospecting the washability and mobility of the harmful elements in coal.
