摘　　要：煤中铝为近年来在我国内蒙古中西部、山西省北部发现的新型的可利用资源。高铝煤主要分布于鄂尔多斯盆地周缘和山西隆起这两大构造单元的石炭-二叠纪的煤层中,靠近阴山古陆南麓,煤中铝含量总体上呈现出西高东低、北高南低的分布变化趋势。煤中铝的这种变化趋势和华北地区晚古生代含煤沉积背景条件密切相关,包括沉积盆地的地形地貌条件、物源所处的位置以及物源区母岩岩石成分等因素。初步估算华北地区可供工业利用的煤中铝资源量达19.5亿t,资源潜力巨大,综合开发利用前景十分广阔。The aluminum in coal is a kind of new available resource recent years found in mid-west Inner Mongolia and northern Shanxi. Aluminum in coal is mainly distributed in Permo-Carboniferous coal seams in the two large tectonic elements of Ordos Basin and periphery,Shanxi uplift. Near the Yinshan old land southern foot,coal aluminum content presents a distribution pattern of high in west and north,low in east and south. This kind of variation trend is closely related to the North China late Paleozoic coal-bearing sedimentary setting conditions including factors of the sedimentary basin topographic landforms,provenance location and parent rock constituents etc. Preliminary estimated coal aluminum can be industrial utilized resources is 1. 95 billion tons. The potential of resource is huge,comprehensive exploitation and utilization prospect very wide.
