摘要
近年来随着矿井开采深度的增加,深井高温热害逐渐成为继水、火、瓦斯、煤尘、冒顶之后的,煤矿第六大灾害。高温不仅影响了围岩的力学性质,而且严重影响矿井安全生产。目前国内矿井,以铁能公司大平矿为例,降温主要采用的还是上世纪沿用下来的氟利昂制冷剂蒸发压缩式制冷机。此类制冷机消耗制冷剂快,管理困难,铜室开凿工程量大,所应用的制冷剂氟利昂为消耗臭氧物质,是臭氧层破坏的元凶,不符合现今煤矿绿色循环可持续发展的经营理念。在拓宽矿井降温渠道,改善井下工作环境,变矿井热害为宝,在降温降湿的情况下对其进行再利用。
With the exploitation depth getting deeper and deeper, the heat-harm has become the sixth barrier after water, fire, gas, coal dust and roof fall in deep mining. High temperature not only influences mechanical property of surrounding rock, but also has great impact on mining safety. The cooling technology in most domestic mines, such as Daping mine affiliated to TF Coal Company, is still using vapour-compression refrigerators with Freon refrigerant as in the last century. This type of refrigerators is refrigerant consuming, hard to manage and difficult in excavation of underground chambers. The refrigerant Freon consumes ozone and destroys ozone layer, which is not in line with the concept of circular economy and sustainable development in green mining. This study aims at exploring cooling methods in deep mines, improving underground working environment and utilising and recycling mine heat with its temperature and humidity controlled.
