Abstract: The paper adopts questionnaire method to investigate the high temperature and heat hazard prevention and control demand in China through online and offline modes. The result shows that the mines that require high temperature and heat hazard prevention and control demand are usually key state-owned coal mines with 1~5 million tons of annual output, 800 meters of mining depth following, and mining working face highest temperature over 30 ℃. Most mines locate at Henan, Shandong, Anhui, Jiangsu and other provinces in China. The mechanical cooling system employed by mines includes partial mobile cooling system, ground centralized cooling system, and underground centralized cooling system, and ice-making cooling system. The existing problems are mainly deficient fund, incomplete cooling effect, high energy consumption, complex system installation and instability of the system. Under the severe situation of coal industry, the coal mine high temperature and heat hazard prevention and control should avoid seeking quick success and instant benefits, to balance the relationship between safety and production on both macro and micro aspects, to form China's own method, theory, technical equipment system, and to promote the development of new technology and new processes, to produce a style of ourselves.
