新疆松树头矿区西勘查区含煤地层及煤层特征

新疆松树头矿区地处天山北麓山前坳陷带,区内含煤地层为侏罗系中统西山窑组。据矿区已有的地质资料以及最新详查成果,认为勘查区总体构造形态为一南倾的不对称向斜,地层倾角普遍较缓,构造简单;西山窑组根据岩性特征分下、中、上三段,煤层主要集中分布在中段,含编号煤层3层、其中以1煤层单层厚度大为特点,厚度为34.32～39.980m,发育稳定,结构简单、区内对比可靠,该资料对该勘查区煤炭资源进一步勘探等工作提供了地质依据。

Coal-bearing Strata and Coal Seam Characteristics in West Exploration Area, Songshutou Mine Area, Xinjiang

The Songshutou mine area is situated in the piedmont geotectogene, at the northern foot of Tianshan Mountains; coal- bearing strata in the area belong to the Xishanyao Formation, Middle Series, Jurassic System. Based on available geological data and new preliminary exploration result, as a whole, the structural form in the exploration area is an asymmetric syncline dipping south gently, thus simple structure. Based on lithologic characteristics, Xishanyao Formation can be divided into 3 members, coal seams are mainly concentrated in the Middle Member, 3 numbered coal seams, in which No.1 coal seam is characterized by its large thickness of 34.32-39.98m, stably developed with simple structure, can he reliably correlated in the area. The result provides geological basis for further coal resource exploration in the area.
