g conclusions were obtained: ① The coal-bearing strata in the area are: There are 4 bottom layers, and the
main structure is 2 large-scale structures; ②The coal measure is the sedimentary of sea-land interaction facies. Sedi⁃
ment accumulation areas are lakes and basins near the sea ③Under the geological action of the exploration area, the
；
coal is gray-black to black, and the coal seam moisture is lower in the north and higher in the south; the thickness of
the coal seam is higher in the middle, and gradually becomes thinner on the north and south sides
