Abstract: Deepwell mining is the most effective solution to resolve the conflict of ore supplies.However, deepwell heat-harm has been endangering the mining seriously.The research results and the current striving direction on control of deepwell heat-harm at home and abroad are analyzed and summarized, and the origin of deepwell heat-harm and its control measures are concluded and compared.Combining with mining conditions in a foreign deep gold-copper mine with high temperature, the control schemes for heat-harm are determined by weighing various factors comprehensively.And waste heat in roadway is eliminated by using cooled inlet wind on the ground, and the water cooling system is applied to treat heat-harm of dead working face, thus providing theoretical support and technical reference for domestic mine with high-temperature.

Key words: Deepwell high-temperature, Heat-harm governance, Cooled inlet wind, Water cooling system
