煤矿井筒供暖技术的研究进展

Research Progress of Shaft Heating Technology in Coal Mines

冬季中国北方煤矿基本都有进风井筒防冻供暖需求,随着环保压力增大,以往的燃煤供暖方式已不满足要求。文章主要介绍了电阻或电磁炉供热、量子能供热机组、燃气或瓦斯锅炉供热、低浓度煤层气蓄热氧化供暖、瓦斯发电余热供暖、空气源热泵供暖等新兴煤矿井筒防冻供暖技术,分析了这些技术的优缺点,提出了这些技术未来的优化改进方向。

In winter,coal mines in north China basically have ventilation and shaft heating needs.With the increasing pressure of environmental protection,the past coal-fired heating mode has not met the requirements.This article mainly introduces the anti freezing heating technology for new coal mines,such as heating with resistance or induction cooker,heating by quantum energy supply units,gas or gas boilers,heat storage and oxidation with low concentration coal bed methane,heat generation by gas generation,air source heat pump heating,etc.The advantages and disadvantages of these technologies are analyzed,and the future optimization and improvement directions of these technologies are put forward.
