Abstract:As mining engineering proceeds to increasingly greater depths, the heat hazard is becoming more serious caused by the surrounding rock heat release, compressed-air energy and geothermal water. Thermal stresses of the working environment significantly affect physiological and psychological of worker, labor productivity, and the failure likelihood of both equipment and workers, and related damage can cause injuries and fatalities. The traditional cooling method cannot be applied in deep mine because of the loss of cool energy largely, poor cooling effect and high cost. The method of heat source control, mechanical refrigeration and individual protection should be adopted simultaneously to control the heat hazard in deep mine, and an intelligent mine ventilation system needs to be established to control the temperature precisely, improve the cooling power and reduce the cost. Although high geological temperature induce heat hazards during mining, they are also an associated geothermal resource. The thermal energy obtained from the synergetic mining of geothermal energy can be cascade comprehensive utilized for heating buildings, bathing, mineral processing and breeding, which can bring huge economic value to the enterprise. At the same time, synergetic mining of mineral and geothermal energy offers a practicable measure to simultaneously control heat hazards at low cost and explore geothermal energy resources, which is a new ideal way to convert harm into profit and waste into treasure.

Key words: heat hazard control; deep mining; synergetic mining; mineral geothermal; intelligent ventilation
