At present, 53% of reserves buried under 1 kilometers in China and the amount of green coal resources is less than 500 billion tons. Ningzheng Mining Area is a newly developed large-scale coal mining area in Western China, and is the main succession area of coal resources in Gansu Province in the future. The coal seams are generally buried more than 1 kilometres. Taking the newly built mines in Ningzheng Mining Area as an example, this paper carried out a geological analysis of thermal environment and analysis of the main influencing factors of thermal hazards, established the model of mine production system, and explored several comprehensive utilization technologies of thermal hazards such as HEMS (High Temperature Exchange Machinery System) cooling technology model and gas, the cooling modes of power generation combined heat, power and cooling system and the artificial ice-making. The cooling technology can effectively guide the development of new mines in Western China in mines and the efficient utilization of resources.
