摘　　要：针对我国矿井严重的热害与地热资源浪费问题,本文研究了地热能开发与热害协同防治技术,提出了现阶段的高效采热和降温方法,利用冷水循环吸热的方式将深部矿井热害防治与地热资源的利用相结合以实现协同开采,并对该方法进行深入的可行性与经济型分析。研究结果表明,该技术既能实现矿井热害的防治又可高效利用深层地热能,在保障井下工作面安全生产的同时开采矿井地热能,有效降低了企业对于热害防治方面投入的成本,为深部资源的煤—热共采提供了一种可行的方案,具有可观的经济与社会效益。In view of the serious heat damage and waste of geothermal resources in mines in China, this paper studies the synergistic prevention and control technology of geothermal energy development and heat damage, and puts forward the efficient mining and cooling methods at the present stage. The method of cold water circulation heat absorption is used to combine the prevention and control of heat damage in deep mines with the utilization of geothermal resources to realize synergistic mining, and the feasibility and economic analysis of this method are carried out. The research results show that this technology can not only realize the prevention and control of mine heat damage, but also effectively utilize the deep geothermal energy. It can ensure the safe production of underground working face while mining the mine geothermal energy,effectively reducing the cost of enterprises in the prevention and control of heat damage, and providing a feasible scheme for the coal-heat co-mining of deep resources, which has great economic and social benefits.
