　　总结了东胜煤田延安组煤的两种主要成煤模式，结合煤质分析数据，探讨成煤环境条件对煤质的控制作用。研究结果显示，河流成煤模式的煤层，煤岩类型以暗淡型为主，煤中富丝质组，煤层中矿物质含量较高，灰分含量多大于10%，煤类以不粘煤为主。湖泊三角洲成煤模式的煤层，煤岩类型以光亮煤和半亮煤为主，煤中富镜质组，煤层中矿物质含量低，灰分含量少于10%，煤类以长焰煤为主。经对比两种成煤模式煤的工艺性质，认为富丝质组煤利于气化、动力燃烧、制吸附剂，富镜质组煤则首选液化和配焦。

This paper summarizes the two main coal-forming patterns of Yan'an Formation in Dongsheng Coalfield, and on this basis, combined with the analysis data of coal quality, the paper probed into the control action of coal-forming en-vironmental condition to the coal quality. The results showed that coal seam formed in fluvial coal-forming pattern made its coal-rock types mainly in the dim briquette, rich in inertinite, high mineral content in coal and ash content of coal more than 10%, the major coal class is non-caking coal;while coal seam formed in the lake delta coal-forming pattern made its coal-rock types mainly in bright-half bright, rich in vitrinite, low mineral content in coal and ash content of coal less than 10%, the major coal class is long flame coal. Finally, on the comparison of the technological properties of two kinds of coal forming pattern of coal, the coal rich in inertinite is appropriate for gasification, power fuel and adsorbent making;while the coal rich in vitrinite, however is good to liquefaction and blending.
