| In order to provide suitable work environment for staff, airflow temperature of roadwaypredicted in the design stage and the location whose temperature may be overrun mustbe determined, so that the temperature of the high temperature roadway can be reduce bytaking Some Relative Measures. The effect factors of airflow temperature of roadwayare analyzed by the theory of heat transfer and fluid mechanics. The theoreticalcalculation formula of airflow temperature prediction and airflow mixed temperature arederived. Mine ventilation simulation system is developed new function of airflowtemperature prediction. Airflow temperature of Changchengwopu coal mine arePredicted. According to the forecast results, put forward the cooling scheme such asincrease air quantity, System optimization and so on. Simulation results show that thescheme cooling effect is obvious. The application results show that the predictionmethod can forecast the airflow temperature of roadway accurately. The predictionmethod provide theory basis for mine ventilation system optimization and determinationof the cooling system. |
