摘　　要：地热异常矿井进入深部开采后热害现象严重。通过对三河尖矿地温场、地温梯度变化规律及岩石热物理性质的分析,揭示三河尖矿深部地温随深度的增大变化异常,大地热流值偏高,为典型地热异常矿井。总结分析得出三河尖模式高温热害特征,即冷源短缺地热异常。针对三河尖模式热害治理,结合三河尖矿地面供热现状,提出三河尖模式热害治理HEMS降温技术,该技术利用井下热水实现井上供热,将产生冷能储存于第四系储能层用于井下制冷,解决热害的同时实现地面供热。三河尖矿成功的实现一期井下热害治理工程,通过对72201工作面降温效果分析,该系统大大改善工作面长期以来高温高湿的工作环境,值得在深部开采及相关领域推广应用。The heat harm is even worse with the increase of mining depth in geothermal-abnormal coal mine. Based on the analyses of geothermal field, geothermal gradient changes and rock thermal physical properties of Sanhejian coal mine, it is revealed that geothermal value suddenly increases and the heat flow values become high with the mining depth increasing, and Sanhejian coal mine is a typical geothermal-abnormal coal mine. Lacking of cold source and abnomal geothermal value is the characteristics of Sanhejian heat harm mode. Focused on the characteristics of Sanhejian heat harm mode, combined with the ground heating problems, a new heat harm control technology, which is named as HEMS（high temperature exchange machinery system） of Sanhejian mode, is proposed. This technology which untilizes the underground heat water to provide upperground heating, has a cold storage in the Quaternary underground storage layer for cooling, the heat harm is resolved and upperground heating is realize at the same time. The first phase of HEAMS is realized in Sanhejian coal mine. Through the cooling effect analysis of working face 72201, the result shows that the working environment of high temperature and high humidity is improved significantly. This heat harm control technology is worth to be applied and popularized in deep mining and related fields.
