Abstract: Abstract: The paper analyzes the geothermal data and tests the sampling rock thermal physical parameters in the mine, the Comsol Multiphysics numerical simulation based on finite element analyzes the geothermal temperature distribution characteristics and heating factors,and makes a verification of actual temperature hole and numerical simulation to study the geo-temperature distribution law of Xutuan Coal Mine and its influencing factors in the main mining area. At the same time, it calculates and obtains the geothermal flow value in the study area, draws a zoning map of the mine's heat impact degree, predicts the range affected by the heat hazard, and provides targeted measures for coal mine heat hazard prevention.
