我国对于煤质分类的研究,虽然已有二三十年的历史,但是一直沿用着很简单的分类法,把煤种分为无烟煤、半烟煤、烟煤、褐煤。这种落后的分类法,已远不能满足我们国家正在突飞猛进的经济建设需要。近几年来,学习苏联先进的工业分类法,根据煤的化学成分,煉焦性能及技术加工特性诸条件,将煤分为泥炭,褐煤、长焰煤,瓦斯煤、蒸发肥煤,煉焦
Although the research of coal quality classification in our country has two or three decades history, it has been followed a very simple classification method, the coal is divided into anthracite, semi-bituminous coal, bituminous coal, lignite. This backward taxonomy is far from satisfying the rapidly growing economic construction needs of our country. In recent years, the Soviet Union to learn advanced industrial classification, according to the chemical composition of coal, coking properties and technical processing conditions of various conditions, the coal is divided into peat, lignite, long flame coal, gas coal, fat coal, coking
