预测井下巷道和工作面的热湿传导是一个复杂问题。热传导方程的理论解法,既不便于运用,也来必适用于井下特定场合。在试图评价井下巷道围岩湿度及热物理特性时也会出现一些困难。 在设计阶段,为确定额外供风量及必要时为创造适宜的工作环境所需的降温能力,需要对井下气候条件进行预测。这对高温深井及利用循环风的矿井尤为重要。
It is a complex issue to predict the heat and moisture transmission in underground tunnels and work surfaces. The theoretical solution of the heat conduction equation is not only easy to use, but also must be applied to the underground specific situation. There are also some difficulties encountered when trying to evaluate the surrounding rock moisture and thermal physical properties in underground tunnels. In the design phase, downhole climatic conditions need to be predicted in order to determine the additional air supply and, where necessary, the cooling capacity needed to create a suitable working environment. This is particularly important for high temperature deep wells and mines that utilize circulating air.
