基于永陇矿区 LYL 勘查区勘探报告的原始检测数据，叙述了勘查区2号、2－3号和3号等主采煤层的基本煤质特征，并分析了煤质差异的成煤环境因素。分析表明：2号、2－3号煤的宏观煤岩类型以半暗煤、暗淡煤为主，3号煤的宏观煤岩类型以半亮煤、半暗煤为主，主采煤层均处于低变质烟煤阶段，显微组分以镜质组为主；灰分含量低～中等，成分以酸性氧化物为主，煤相指示陆相成煤；区内以低～特低硫煤为主，区内各种硫主要以硫化铁硫为主，硫分经浮选后，分离降解效果显著；成煤环境的差异与煤质的变化关系密切。
基于永隴礦區 LYL 勘查區勘探報告的原始檢測數據，敘述瞭勘查區2號、2－3號和3號等主採煤層的基本煤質特徵，併分析瞭煤質差異的成煤環境因素。分析錶明：2號、2－3號煤的宏觀煤巖類型以半暗煤、暗淡煤為主，3號煤的宏觀煤巖類型以半亮煤、半暗煤為主，主採煤層均處于低變質煙煤階段，顯微組分以鏡質組為主；灰分含量低～中等，成分以痠性氧化物為主，煤相指示陸相成煤；區內以低～特低硫煤為主，區內各種硫主要以硫化鐵硫為主，硫分經浮選後，分離降解效果顯著；成煤環境的差異與煤質的變化關繫密切。

Based on the raw data of LYL exploration area exploration report in Yong-Long mining area,the basic characteristics of coal quality in main coal seams such as No. 2,2 -3 and 3 coal seam,were narrated. At the same time,the coal forming environment factors which led to coal quality difference were analyzed.The analysis shows that,No.2 and No.2 -3 coal are mainly semidull coal and dull coal,No.3 coal is mainly semibright coal and semidull coal.The main coal seams are all in low rank bituminous coal stage,the maceral is mainly vitrinite;the ash content is low- medium and the main component of ash content is acidic oxide,continental facies coal forming are indicated by coal facies ;the coal in this area is mainly the low-especially low sulfur coal,iron sulfide sulfur is the main sulfur existing way,after the flotation of sulfur,the separation and degradation effect are significant;the differences of coal forming environment are closely related to the change of coal quality.
