| Abstract: | South Shaozhai well field in Lingtai County is the southwest extending part of the Binehang coal mine of Jurassic Huanglong coal field. In the well field the Yan ＇an Formation is a set of coal-bearing rock system of continental sediments in the river marsh fluvial and swampy sediments. Based on the analysis on the data from the drill core coneerning sedimentary nature, structural geology, coal beds and mainly mineable coal beds and its relationship with the structure, the sedimentary features of the strata coal-bearing are concluded in this paper. This would benefit to the mining of the coal beds in the future. |
