In this paper, The airflow and rock wall in the area of Dalong mine ventilation system was chosen as the research object, the whole-field solution method was used to simulate the groundwater seepage and ventilation roadway environment. It researched the law about surrounding rock and environment of roadway with the change of Darcy number and Rayleigh number. The analysis result shows that the groundwater has a significant impact on temperature field under the action of dead weight. With the increase of Da number, temperature gradient reduces significantly near the surrounding rock of roadway, and the air in the surrounding rock of roadway becomes bifurcation phenomenon, convection is weakened ,heat transfer is weakened accordingly; With the increase of Ra number , the convection of the air in the surrounding rock of roadway reinforces ,heat transfer reinforces correspondingly.
