摘要
本文采用低温灰化仪分离了我国１８个煤样中的矿物质，用Ｘ射线衍射法对它们进行鉴定。根据煤灰化学成分分析结果，参照矿物标准成分推算各矿物相在煤灰中的含量。本文还总结了我国煤中矿物质的特征，并初步探讨了煤中矿物质组成与沉积环境之间的关系。
The mineral matter has been separated from 18 coal samples with a low temperature asher,and analyzed by means of X-ray diffraction method.Based on the results of chemical analysis of the coal ash, with reference to the standard composition of minerals the content of various mineral phases in the coal ash has been determined.Furthermore,this paper summarizes the mineral matter characteristics of the coal samples and discusses the relationship between the composition of mineral matter in coal and its depositional environment
