The gas situation in the M7 lower coal seam in the No.1 coal mine of Yuka has only been reported by the appraisal report of the gas level, and the results of the gas accumulation situation in this seam are in a blank state. In order to ensure the safety of mining the coal seam under M7 lower, the basic parameters of gas in this seam are examined, and the influence factors of burial depth and structure on gas pressure and gas content are studied. The results of the study show that: the closed structure of backslope leads to an increase in gas content and gas pressure, and the open structure of faults and other faults leads to a decrease in gas pressure and gas content; and empirical formulas are established for gas pressure-buried depth and gas content-buried depth. The research results and methods are of great significance for the study of gas storage in other mines.
