No gas pressure measurement has ever been carried out in the M7 lower seam of Yuka No.1 coal mine and only the gas level appraisal has been carried out in the whole mine. With the continuous extension of the mining depth of the M7 lower coal seam, the problem of predicting gas disaster has gradually appeared. In order to prevent gas accidents from occurring in the deep mining process, the gas pressure of the M7lower coal seam was measured. The technical process of gas determination is introduced, and the maximum gas pressure is 0.41MPa through on-site determination, and the buried depth of the measurement point is 689.72m, which is comprehensively analyzed, and the gas disaster is gradually revealed with the increasing mining depth.
