| 摘 要： | 目前,我国对煤的定义似乎很明确,但在实际应用中会遇到煤与非煤的界定问题,其势必影响到煤炭的合理划分及应用。为此从煤的沉积及变质演化入手,明确煤与炭质泥岩、天然焦、石墨等演化关系,进而从其相互间的物质成分差异、变质程度及宏观与显微特征差异加以界定,初步总结出划分煤及其相邻非煤类别的灰分、水分、变质程度、宏观和显微的差异特征,为后续煤和邻近非煤划分提供理论参考。

| Abstract: | At present,the definition of coal seems clear,but in practices will often have problems of how to distinguish coal and non-coal,thus is bound to impact reasonable division of coal and its application.The paper starts from the coal deposition and metamorphic evolution,clarifies evolutional relationship between coal and carbargillite,natural coke and graphite.And then have defined their material composition,degree of metamorphism,macroscopic and microscopic features differences.Initially summed up and defined coal and approximate non-coal differential characteristics from ash content,moisture,degree of metamorphism,macroscopic and microscopic features.The study has provided theoretical reference to define coal and approximate non-coal henceforth. |
