广西早石炭世寺门时煤质特征

本文是在前人的煤岩、煤质测试成果与资料基础上进行初步综合研究,试对广西早石炭世寺门时煤质特征及其煤的用途进行探讨。根据煤岩学和煤盆地相分析认为:广西寺门时煤主要聚集于煤盆地的滨岸碎相带和潮坪—沼泽相带中;煤种以无烟煤为主,少量的贫煤与瘦煤,无烟煤仅硫量稍高其余各项指标符合优质煤的标准,可用于合成氨及动力燃料。

THE CHARACTERISTICS OF THE COAL SEAMS OF SIMEN AGE OF EARLY CARBONIFEROUS IN GUANGXI

Based on previous work on coal and analysing data, this paper has a discussion on the characteristics and uses of the coal of Simen Age of Early Carboniferous in Guangxi. On the basis of the coal petrology and the facies of the coal basin, it is suggested that the coal seams were mainly formed in the littoral facies and tidal - swamp facies. The coal types are largely composed of anthracite and subordinate amount of meagre coal and lean coal. The anthracite meets various requirements set for good quality coals only except its slightly higher sulfur content and may be used for the synthesis of ammonia and as fuel for power generation.
