新疆富蕴县喀木斯特煤田喀拉萨依勘查区煤岩层对比

Correlation of Coal Seams and Rock Strata in Karasay Exploration Area,Kamst Coalfield,Koktokay County,Xinjiang

新疆富蕴县喀木斯特煤田喀拉萨依勘查区位于准噶尔盆地东北缘,整体构造为一向西北倾斜的单斜构造,主要含煤地层为八道湾组和西山窑组,其中西山窑组B1煤为全区可采煤层。通过分析喀木斯特煤田喀拉萨依勘查区施工的地质钻孔资料,采用标志层、层间距、煤岩性组合特征及物性特征等方法对勘查区八道湾组和西山窑组进行了系统划分和对比。对含煤地层及煤层的分布规律进行了分析,其结论对以后设计施工具有现实意义。

The Karasay exploration area, Kamst coalfield, Koktokay County in Xinjiang is situated at the northeastern margin of the Junggar Basin, the overall structure is a monocline dipping northwest. Main coal-bearing strata belong to Badaowan and Xishanyao formations. The coal B1 in the Xishanyao Formation is a whole region mineable coal seam. Through the analysis of geological borehole data in the area, carried out systematic partition and correlation of both formations through marker bed, bed interval, coal and rock assemblage and physical characteristics. The distribution pattern of coal-bearing strata and coal seam have been analyzed, the result has practical significance in exploration design and operation henceforth.
