新疆阳霞矿区含煤地层特征及聚煤规律浅析

PRELIMINARY DISCUSSION ON COAL-ACCUMULATION REGULARITY AND THE DEVELOPING CHARACTERISTICS OF COAL-ROCK-MEASURES IN YANGXIA MINING AREA

阳霞矿区位于新疆塔里木盆地北缘含煤区东段,依据多年在该区域进行煤田地质勘探的资料,对区内地层构造及含煤地层发育特征进行了阐述.根据含煤岩系组合特点,对其沉积古地理环境进行了初步确定和划分,对下侏罗统塔里奇克组和中侏罗统克孜努尔组所含煤层中的聚煤沉积特征进行了粗浅的分析.另对煤层火烧带分布特点及自燃现象进行了解释,以期对阳霞矿区今后的勘查有一定的指导作用.

Yangxia mining area locates in the east part of Talimu basin. Based on the experience of geological exploration in this area, the author has a systemic describing of the structure and the developing characteristics of coal-rock measures in this area. According to it＇s constitution characteristics of coal measures, the author clearly determined it＇s geology sedimentary environment, and analyzed the coal-accumulation regularity of Taliqike formation of lower Jurassic and Kezinuer formation of middle Jurassic. Finally, it analyzed the reason and the distribution characteristics of the burnt coal area.
