Abstract

Taking Bulianta Coal Mine as the background, this paper uses theoretical analysis, numerical simulation and field practice to study the air leakage laws of Bulianta Coal Mine. The results show that, in the horizontal direction of the working face, the air leakage intensity is positively correlated with the length to the working face, and the closer to the working face is, the greater the air leakage intensity is; in the direction of inclination, there is an increasing trend of air leakage from the transport lane to the return air lane; in the vertical direction, the degree of air leakage is closely related to the height of the stratum, and in the higher level, the air leakage intensity changes slowly.
