| 摘 要： | 我国西北侏罗纪煤储量巨大，煤质优良，多低灰、低硫，被称为“优质煤”。在总结前人研究成果基础上，对其煤岩学特征及其地质控制因素进行了探讨。研究认为，不同地质背景下形成的煤其煤岩学特征表现各异，如新疆的艾维尔沟、阜康等矿区的煤可用于炼焦，神华煤可直接液化，吐哈盆地的煤具有成油潜力。西北中侏罗世煤普遍富含惰质组，贫矿物质最为显著，与我国东部石炭－二叠纪煤以及国外“冈瓦纳煤”均存在较大差异，西北侏罗纪煤煤岩类型独特，是大型内陆型盆地演化的产物，多属低变质烟煤，局部也有中、高变质烟煤和无烟煤，还出现一个褐煤矿点。在煤地质学与煤岩学、煤化学等方面的深入研究,对今后洁净、高效、合理地利用西北侏罗纪优质煤资源十分重要。

| Abstract: | Jurassic coal in NW China is named as coal with good quality with huge reserve and perfect coal quality,mostly with low ash content and low sulfur content.The coal petrology and its geological controlling fac-tors are discussed.For example the coals in Aiweier,Fukang and other mining areas in Xinjiang Autonomous Re-gion can be used in coking.The direct coal liquefaction has achieved success in Shenhua.Coal derived oil has been recognized in Tuha Basin.However,this type of coal has specific coal composition ... |
