Abstract：In order to solve the problem of coal mine gas overrun, Zhenchengdi Mine was taken as the research background, the gray correlation method was used to analyze the factors that affect the gas overburden of the mine, and the thickness of overburden with the greatest impact on the gas overburden was found. At the same time, the numerical simulation software was used to study the gas pressure in the rock layer, and the gas pressure showed an increasing trend outward along the central axis of the borehole. The maximum value of simulated gas pressure was 0.52 MPa. Finally, the gas outburst prevention research was carried out in Zhenchengdi Mine. Through drilling drainage, the gas content of the mine was effectively controlled, and the gas pressure of the mine was reduced, which provided a certain reference for normal production mining of the mine.
