Abstract

To solve the problem of unsatisfactory cooling effect of local cooling systems in coal mining faces, this paper constructs a simulation model of the working face, combines theoretical analysis and numerical analysis, and studies the influence law of four factors on the cooling effect in the cooling system (the combination of the air cooler Ca, the air distance of the wind cylinder Da, the length of the wind cylinder Ld and the air temperature of the air cooler T0). The results show that when Da = 25 m, Ld = 100 m, T0 = 19 °C C2 air cooler combination method, the average air temperature of the inlet roadway is reduced by 5.1 °C, the average air temperature of the working face is reduced by 3.8 °C, the average temperature of the return roadway is reduced by 2.4 °C, and 97 % of the area of the coal mining face is < 30 °C. Finally, the application was carried out at the site of 10303 working face, and the average temperature was reduced by 3.9 °C, the maximum air temperature dropped to below 26 °C, and the minimum temperature was as low as 24.3 °C. The thermal environment of the coal mining face was effectively improved, and the cooling effect of the cooling system was substantially improved.
