日本高温矿山较多,降温措施对这些矿山是一项重要研究课题。要研究合理的降温措施,就必须正确地预测井下风流的温度及湿度。平松、天野、小门的研究小组20多年来对于这个问题进行了种种研究。综合这些研究结果,考虑风巷壁画上水的蒸发而提出了计算风流温度和湿度的实用方法。该论文假定由于围岩内热传导而到达岩石壁面上的热流不太受风巷壁面上水分蒸发的影响。
Japan’s high-temperature mines more cooling measures for these mines is an important research topic. To study a reasonable cooling measures, we must correctly predict the temperature and humidity downhole wind. Hiramatsu, Amano, wicket research team for 20 years conducted a variety of studies on this issue. Based on these findings, a practical method of calculating the temperature and humidity of the wind flow is proposed considering the evaporation of the water on the murals of the wind and laneways. This paper assumes that heat flow to the rock wall due to heat conduction in the surrounding rock is not affected by evaporation of moisture from the wall of the wind tunnel.
