Analysis of the characteristics of geological control on coal and mining conditions of Jiangjiahe coal mine in Binchang mining area

This paper is based on the geological exploration data and the actual data collected in the production process, analyzed systematically the development types and plane distribution characteristics of geological structure, the development characteristics of coal-bearing strata and base paleotopography, and the temporal and spatial relations of coal seams and the characteristics of coordination with mining area structures in the southern margin of Binchang mining area. It confirmed:Jiangjiahe minefield in the southern margin of Binchang mining area has undergone the Triassic period, the tectonic evolution of each stage was basically synchronous with the tectonic evolution of Ordos basin; the development of main mining seam 4 was influenced by the development of Triassic basement paleotopography, Jurassic fluvial-lacustrine sedimentary environment and regional tectonic development, and the thick coal area is located in the south of Binxian anticline and the axis of Zhaopo syncline; the southern margin of Binchang mining area is rich in coal resources and has excellent coal quality, good mining conditions, good mining value and economic benefits. In view of the problems such as gas exceeding the limit, water sprinkler floor bulging and so on, measures can be taken to achieve safe mining.
