煤炭是植物遗体埋藏在地下经过漫长复杂的生物化学、地球化学和物理化学作用转化而成的一种固体可燃矿产。文中简要论述了煤炭的生成阶段及其主要元素成分并对近年来煤炭的地位及其发展做了简要讨论。
Coal is a solid, combustible mineral that has been buried in the earth under long, complex biochemical, geochemical and physico-chemical processes. This paper briefly discusses the formation stage of coal and its main elements and components and in recent years the status of coal and its development made a brief discussion.
