摘要: 煤矿的深部开采是我国资源发展的趋势,但随着深度的增加,热害问题越加严重,危及到煤矿行业的生产安全。国外的大型机组制冷方式,虽然可以达到井下降温的目的,但由于消耗大量的电能而不能在我国得到广泛地利用。以地热能利用技术为代表的新一代能源利用技术,以其运行费用经济、环保、可靠,得到了发展利用。本文以夹河矿为例,运用地层储冷井下降温技术,把低焓地热能和风能结合起来,将冬季空气的冷能储存在浅部地层中,辅以井上及井下换能系统,解决井下热害问题。Abstract: Deep exploitation is the trend of development of resources in China.But the deeper of mining depth becomes,the more heat-harm is in deep mining,which results in miners working in a dangerous mine.Foreign large refrigerator units may reach the goal of cooling under mine,but they consume vast electric energy,so they can not be used widely in China.As a representative of new resources utilization technologies,geothermal energy utilization technology has many traits,such as economical operation cost,environment-protected and reliability,so the technology is developed and utilized.This paper takes Jiahe mine as an example,utilizing the technology of aquifers for cold energy storage,low enthalpy geothermal energy and wind energy are combined to store the cold energy in winter into shallow aquifers.Together with the HEMS,heat-harm is to be fathered.
