Abstract：As the larger of the mining depth is，the higher ground temperature follows；the higher ground temperature follows，many secondary disasters of deep mining are induced by the thermodynamic effect of deep rock；so it is necessary to study the rock mechanics-related problems in deep mine of high ground temperature. This paper firstly summarizes three different modes of the deep mine geothermal field，the linear mode，the nonlinear mode and the abnormal mode，and then researches on the deep rock strength and adsorption effect impacted by temperature using laboratory experiments. The experimental results show that，as the temperature increases，the strength and elastic modulus of rock significantly reduces，and the adsorbed gas becomes free gas overflow，which are closely related to the disasters of collapse and methane gas burst in coal mine. Based on summarizing the temperature control technologies at home and abroad，the HEMS cooling technology is proposed using underground water in mine as cold source；three typical modes of cooling measures are put forward which have been verified through in-site testing. When the system is running，temperature of cooling face is lower than 29 ℃，face temperature decreases 5 ℃–12 ℃，relative humidity decreases 5%–15%. Finally，an effective method for evaluating effectiveness of mine cooling system is proposed.
