This article is guided by the theory and method of sedimentology and petrology,based on the data of field outcrop,drilling core,logging curve and other data,and combination of macroscopic analysis and microcosmic study. Combining with the research results of other areas in North China Basin,the sedimentary facies type and coalite effect of coal in the coalfield have been discussed. The results show that the coal strata of Hanxing coal field deposites from the Carboniferous to the Early Permian,and experiences the evolution of the sedimentary environment in the tidal flat and shallow water delta. The shallow water delta of Permian develops the stable and recoverable 2 Coal seam.
