摘要
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。
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.
