Study Of Temperature Distribution Of Roadways Based On Heat Exchange Theory

With the increasing of mining depth, the number of high temperature mine has beenincreased and the harm degree has been serious day by day, which due to the release anddiffusion of heat source or other reasons. This not only threats mine workers’physiological and psychological health badly, but also influences the work efficiencyand personal safety of miners. More over, it’s easy to cause safety misadventure andequipment accident. We must do some research on the formation and principle of theheat damage, master the factor that effects the high temperature mine and it’s influencedegree, and build the prediction method of deep well thermo-dynamic parameters, so asto take effective measures to cool down. Therefore, further improving of the hightemperature condition and miners’ working environments is really urgent and hasimportant practical significance.In this paper, it uses the method of mathematical analysis and the principle of heattransfer and thermodynamics. Firstly, it gives a detailed analysis of the heat source indeep well and its influence to air temperature. Secondly, according to thethermodynamic balance in the process of heat exchange in tunnels, it builds the airthermal balance equation. At last, it calculates the air temperature of the tunnels, themining face and the tunneling face, and finally makes a numerical simulation of welltemperature profile under fire conditions.
