西南地区等变质煤煤岩煤质差异性研究

STUDY ON THE DIFFERENCES IN COAL PETROLOGY AND COAL QUALITY OF ISOMETAMORPHIC COALS IN SOUTHWEST CHINA

通过对西南地区古生代受海影响煤和陆相煤以及中生代陆相煤３个系列煤样的对比研究，探讨了西南地区煤岩及碳、氢、氧、氮等元素的含量特征；首次提出了只要煤化程度恰当。

Based on the comparative studies of three series of coal samples i.e.,the Palaeozoic marine influenced coal and terrestrial coal,and the Mesozoic terrestrial coal,the coal petrology and the content properties of C,H,O,N and other elements in Southwest region are explored.A viewpoint that the caking property of Mesozoic coal is not weaker than that of Palaeozoic ones,Provided that the coalification degree is proper,is presented for the first time.
