Analysis on Influence of Temperature Distribution in Strata Rock on Airflows Temperature and Humidity in Wet Airway

摘要：

Its used to assume that the initial temperature in the surrounding rock equal to strata rocks original temperature, when the break-though airways thermal climatic conditions was simulated. Actually the temperature distribution in the surrounding rock is not uniform because that different parts of the airways ventilation time are not same. The Influence of initial temperature distribution in strata sock on alrflows temperature and humidity in wet airway is studied. It is revealed that the initial temperature distribution in surrounding rock has a greater influence on airflows temperature and humidity. If the average original temperature distribution is assumed as the initial temperature when the break-through roadway is formed, the error is quit big, especially in the early stage of break-though. The error increases with the length of ventilation airway, and decreases with the roadways ventilation time after, break-through. Therefore, the asymmetric distribution of strata rocks temperature should he considered in simulation of airflows temperature and humidity of airway after break-through.
