The Xiheishan Mine, situated in the southeastern part of the Zhundong coalfield within the study area, is characterized by its coal-bearing strata, such as the Xishanyao Formation (J2x), which comprises a diverse range of fluvial facies, delta facies, swamp facies, and shallow lake facies deposits consisting of fine-coarse sandstone, siltstone, mudstone, and coal seams.
The Xishanyao Formation consists of terrigenous deposits dominated by gray–white sandstone, gray–black mudstone, and coal seams, with braided river delta and lacustrine sedimentary systems. During the Middle Jurassic, the eastern Junggar Basin was in an extensional subsidence state, forming a large, shallow intracontinental sag coal basin. From the late Middle Jurassic to Late Jurassic, influenced by peripheral block collisions, the basin entered a transpressive tectonic phase, which profoundly affected the coal-forming environment, causing variations in coal seam thickness and diversifying sedimentary environments.
In the Jiangjungebi No. 1 Open-pit Mine, the coal seams are numbered from top to bottom as B7, B5, B3’, B3, B2, and B1. Among them, three fully minable seams (thickness > 1.00 m) are B5, B3, and B1; the B2 seam is mostly minable; B3’ is locally minable, and B7 is unmineable. The six coal seams have a total average thickness of 50.49 m and an average clean coal thickness of 49.32 m. The average gangue thickness is 1.45 m, with a gangue ratio of 2.87%. The B5, B3, and B1 seams have a total average thickness of 49.58 m and an average clean coal thickness of 48.47 m. B5 is a fully minable seam with an average clean coal thickness of 21.49 m; B3 is a fully minable seam with an average clean coal thickness of 6.34 m; B1 is a fully minable seam with an average clean coal thickness of 20.43 m.
