入风调温系统热交换规律研究与应用

RESEARCH AND APPLICATION OF HEAT EXCHANGE REGULARITY IN AIR-INLET TEMPERATURE-REGULATING SYSTEM

通过研究矿井入风调温系统的空气与岩体热交换规律，提出了改善矿井通风的一种新方法。研究结果表明．对于我国北方矿山，此方法既可防止入风并结冰，又可降低入风温度，为改善矿井通风状况创造了有利条件。而且投资少、耗能低、效果好，应用前景广阔。

Based on the research on the heat exchange regularity between air and rock in air-inlet temperature-regulating system, a new method for improving mine ventilation is presented. The results of theresearch show that for mines located in northern china, the method can prevent from ice accretion in air-inlet shaft and decrease air-inlet temperature, thereby create a favorable condition to improve mine ventilation. It has a wide application perspective for Iittle investment. low energy consumption and fine effectiveness.
