Abstract
Coalfield in Puyang-Huaxian area, Henan Province, is located in Neihuang salient within the North China depression inthe 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 south- weatward 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-medi- um 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.关键词
