宁夏红墩子矿区高铝煤炭资源特征初探

Preliminary study on characteristics of high alumina coal resources in Hongduanzi Mining Area of Ningxia

在收集了红墩子矿区勘探时期的大量钻孔资料基础上,对煤层、煤质化验数据进行整理分析,发现各可采煤层煤灰成分中氧化铝含量较高,平均含量达到35%~40%,其中5号煤层含量最高,并且其含量分布在平面和垂向上均具有一定的规律性。同时研究发现,成煤地质条件是高铝煤炭形成的关键因素。

On the basis of collecting a large number of borehole data during the exploration period in Hongduanzi mining area,the paper collated and analyzed the coal seam and coal quality test data,and found that the content of alumina in the coal ash composition of every recoverable coal seam was higher,the average content reaches 35%~40%,and the content of No.5 coal seam is the highest,and its content distribution has certain regularity in plane and vertical.At the same time,it is found that the geological condition of coal formation is the key factor of high-alumina coal formation.
