利用浅部地层调温降低深井入风温度的试验研究

Testing and Studying of Decreasing Air inlet Temperature of Deep Mine shaft by Temperature Regulating of Shallow Ground

根据空气与岩体的热交换原理，探讨了利用浅部地层调温作用来降低深井入风温度的可行性。现场试验研究结果表明，对于我国北方深矿井，浅部地层调温作用可使入风温度大幅度降低，可改善深部作业面的热环境状态；而且在一定的开采深度范围内，该方法最为经济。

Based on the heat exchange theory between air and rock,the feasibility of decreasing air inlet temperature by temperature regulating action of shallow ground is discussed.The testing studying results in site show that for deep mine shaft located in the north of China,the air inlet temperature can be decreased greatly by the temperature regulating action of shallow ground,and the heat environment condition in the depth of mine can be improved,therefore,it is a most economical means in fixed range of mining depth.
