河南省濮阳-滑县一带煤田地质特征
|
摘要
河南省濮阳-滑县一带煤田位于华北陆块南部华北坳陷之内黄凸起,地层分区属华北区华北平原分区豫北小区。通过地震剖面工作,在其控制的范围内,经过钻探验证,普遍存在二1煤层,其底板标高为-1000 m～-1650 m,含煤地层是一个走向北东的单斜,向西南倾伏,倾角为6°～8°。二1煤底板为深灰色致密泥岩或为砂质泥岩;顶板为炭质泥岩、泥岩、砂质泥岩、粉砂岩、细-中粒砂。二1煤层厚度5.15 m～8.50 m。煤质以亮型、半亮型块状煤为主,属低硫中低灰分高发热量的优质煤。
Coalfield in Puyang-Huaxian area,Henan Province,is located in Neihuang salient within the North China depression in the south of the North China Craton,and stratigraphically belongs to the North Henan plot of the North China Plain division of the North China district.Through the work of seismic profiles,in its coverage,the drilling verified that there is widespread existence of "second1" coal beds,,their bottom elevations are-1000～-1650m,the coal-bearing strata form a NE-trending monocline,with a southweatward plunge of 6-8 °.The floors of "second1" coal beds are formed of dark grey dense mudstones or sandy shale,the roof are formed of the carbargilife,mudstone and sandy mudstone,siltstone,fine-medium grained sand.The thickness of "second1" coal beds is 5.15～8.50 m.The coal quality is predominated by bright and half bright massive coal belonging to the low sulfur,low ash and high heating value high quality coal.
