摘要煤中常量元素(包括Na、Mg、Al、Si、K、Ca、Ti、P和Fe)是煤的重要无机组成,也是影响煤物理化学性质及加工利用的主要影响因素。本文结合华北鄂尔多斯盆地、开滦矿区和峰峰矿区晚古生代煤、贵州西部晚二叠世煤的具体实例,对煤中常量元素的赋存状态、地质成因和指相意义进行了总结,并对煤中常量元素在煤加工利用过程中的影响做了简要陈述。 Major elements, including Na, Mg, Al, Si, K, Ca , Ti, P, and Fe, are important inorganic compositions of coal. Meanwhile they are the controlling factors both for physical and chemical characteristics of coal and for coal procession and utilization. Combined with the cases of the Paleozoi c coals from the Ordos Basin, the Kailuan Coalfield and the Fengfeng Coalfield i n North China, and the Late Permian coals from western Guizhou Province, this pa per summarized the modes of occurrence, geological genesis, and genetic signific ance of major elements in coal. In addition, the influences of major elements on the coal procession and utilization are simply stated.
