摘　　要：为加快陕北侏罗纪煤田煤炭资源分质分级进程,在整理分析各井田地质勘查成果资料的基础上,通过对神府矿区各主要煤层的煤岩煤质分析、微量元素测试及综合对比,探讨其清洁高效利用及绿色开发的途径并提出合理的开发建议。结果表明:神府矿区各煤层原煤以低灰、中高挥发分、高热值煤为主,煤中有害元素富集度低,原煤洁净等级为Ⅱ级;浮选后,多达到Ⅰ级。建议开发过程中,加强对煤岩煤质、煤中金属元素的研究,加大地下气化、直接液化等绿色开采技术的应用。In order to speed up the grading process of coal resources of Jurassic coalfield in northern Shaanxi,based on collating and analyzing geological exploration data of well fields,clean and efficient utilization and green development approaches were discussed through coal and rock quality analysis and trace element test and comprehensive comparison of each main coal seam Shenfu mining area.The results showed that the raw coal of each coal seam in Shenfu mining area had mainly low ash content,medium and high volatilities,high calorific value and low concentration of harmful elements.The clean coal grade of raw coal was GradeⅡand reached GradeⅠafter flotation.It was suggested that in the development process,research on coal quality and metal elements in coal should be strengthened,and application of green mining technologies such as underground gasification and direct liquefaction should be increased.
