摘要
煤矿开采深度不断加深,随之而来的热害问题越来越严重.能源危机推动地层能、风能等新型能源的发展利用.地层储冷技术是将地热能和风能相结合,利用地层储存冬天空气的冷能,辅以换能系统,解决井下降温问题.以夹河矿为例,以该矿的地质条件、热力学及水力学参数为设计参数,采用数值模拟方法,对储冷系统的等温线、不同温度范围冷水体体积进行了数值模拟分析.从理论上证明了储冷系统储冷和制冷的可行性,可储存和提供足够的冷量用于深部矿井降温.研究成果可为我国矿井节能减排提供有益的思路.
The deeper of mining depth becomes, the more heat-harm is in deep mining. Lack of energy promotes the development and utilization of geothermal energy and wind energy etc. The technology of aquifers to store cool energy combines geothermal with wind energy. Aquifers storing the cool energy of wind in winter~ with the help of exchange energy system, the problem of deep mine heat-harm is solved. This paper takes Jiahe mine as an example, using its geological condition, thermodynamic parameter and hydraulic parameter as designing parameter. With the method of numerical simulation, the isothermal line and the volume of cool water in different temperature range in the system of storing cool energy system are analyzed. It is proved theoretically that the feasibility of the storing cool energy, which could store and supply enough cool energy to father deep mine heat-harm. The results can provide a good idea to saving energy and emission reduction in China coal mines. 9figs., 3tabs., 9refs.
