Study on coal- accumulating characteristic of Shanxi formation and low Shihezi formation in Yongcheng Coalfield,Henan province
摘要
Abstract
Based on the theory of sedimentology and coal field geology, a systematic analysis is carried out on the sedimentary environment and coal accumulating characteristics of the lower Permian Shanxi and Lower Shi- hezi Formation in Yongcheng Coalfield of Henan province. The research shows that the sedimentary environ- ment of the lower stratum of Shanxi formation is considered as the tidal flat, and the upper stratum and the Lower Shihezi formation is the result of delta systems. The occurrence, hosting, thickness and distribution of the coal seams are controlled by depositional environment. The major ruinable coal seam Shan~ formed in peat flat of tidal flat, and its thickness is negatively correlated with the underlying sand; the coal seams of Lower Shihezi formation formed respectively in the peat swamp of construction stage and abandonment stage of delta plain.关键词
