摘　　要：为促进宁夏优质煤炭资源的清洁高效利用,对全区无烟煤的煤岩煤质特征及洁净等级进行详细对比分析,在全面掌握宁夏无烟煤资源禀赋的基础上,总结提出宁夏无烟煤的深加工洁净利用途径。碱沟山矿区和汝箕沟矿区无烟煤变质程度高,已具有一定石墨化程度,且原煤综合评价洁净等级均为Ⅲ级,属高质量洁净煤,均可作生产炭素材料、超纯煤、低灰活性炭、碳化硅的还原剂以及石墨制品和无烟煤基导电高分子材料等的原料。韦州矿区和马莲滩矿区无烟煤为中高变质程度,原煤综合评价洁净等级分别为Ⅳ级和Ⅵ级,属中等洁净煤和差洁净煤,煤质指标达到一般工业用煤标准,可用作气化用煤等。In order to promote the clean and efficient utilization of high-quality coal resources in Ningxia,the characteristics of coal quality and clean grade of anthracite in the whole region were analyzed in detail,the way of deep processing and clean utilization of anthracite in Ningxia is summarized.The anthracite in Jiagoushan mining area and Rujigou mining area has been highly metamorphosed and graphitized to a certain degree,and the clean grade of raw coal is grade Ⅲ,which is a good clean coal,can be used as carbon materials,production of ultra-pure coal,production of low-ash activated carbon,production of silicon carbide reductant and as graphite products and anthracite-based Conductive polymer materials,etc..The anthracite in Weizhou mining area and Maliantan mining area is of medium and high metamorphic degree,and the comprehensive evaluation of raw coal is grade Ⅳ and Ⅵ respectively,which belongs to medium and poor clean coal,it can be used as gasification coal and other general purposes.
