摘要
结合神府矿区郭家湾勘查区煤炭勘查工作成果,系统分析研究区可采煤层的煤岩特征、煤质特征及其变化规律,确定了区内煤类、煤岩类型,并初步评价煤炭的液化性能。研究结果表明:有机显微组分中镜质组含量为45%,惰质组含量为52.3%,壳质组少量(含量0.9%);无机组分以碳酸盐矿物为主,含少量黏土矿物;煤质总体以特低-低灰、特低硫、高发热量的不黏煤为特征;直接液化用煤主要分布在研究区东北角5-2煤层,资源量约为1 501万t,该区其他煤层煤基本不适合直接液化。
Combined with the work product of coal exploration in Guojiawan exploration area of Shenfu mining area, the coal petrography characteristics, coal quality characteristics and change law of workable coal seam were systematically analyzed, furthermore, the coal type and lithotype in the region were determined, and the liquefaction properties were evaluated preliminarily. The results showed that, the vitrinite accounts for 45~ in organic maceral, inertinite accounts for 52. 3%, exinite group accounts for 0. 9~ which is quite little; the inorganic constituents are mainly the carbonate minerals, a small amount of clay minerals are existed. The coal quality generally is the extra low-low ash, extra low sulfur, high calorific value non caking coal. The direct liquefaction coal is mainly distributed at 5-2 coal seam in northeast corner of the research region, the resource is about 15010 thousand ton, the coal from other coal seam is not suitable for direct liquefaction.
