深井矿山热源分析及降温技术探讨

Heat source analysis and cooling methods discussion of deep mine

近年来,我国许多矿山已转入深部开采,随着矿山采深增加,井下气温急剧升高,将成为影响安全生产的主要灾害之一。本文对深井矿山井下热源分布及形成机理进行了定量及定性分析,在此基础上,进行了深井矿山井下降温技术探讨,为矿山设计、回采工作提供一定的依据。

Many mines in our country change to deep mining in recent years. Following the increasing mining depth, the temperature of underground mine will increase rapidly, and this high temperature will become the main disaster which can influence the production safety of mine. This paper qualitatively and quantitatively analyzed the distribution of heat sources and their formation principles. Based on the above, the cooling methods for deep mine were also discussed, thus provided foundation for design and mining work of mine.
