Abstract：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.
