Abstract: This paper briefly introduces the latest laws and regulations related to coal industry hvac, under the new policy and the situation is analyzed, the coal industry development direction hvac design. In accordance with the new heat source of heat transformation and faced to the mine design problem, respectively discusses the gas boiler heating plan and thermal storage, coal-fired boiler heating boiler heating solutions, solar heating, air compressor heat heating scheme and waste heat utilization in mine spent heating heat source scheme and design principle. Analyzed the six heat source heating operation cost, analyzes the advantages and disadvantages of various options. Results show that the solar energy and waste heat of air compressor in mining area is insufficient, the lowest cost of coal-fired boiler running relatively most provinces, but the cost is the highest, gas boiler cost is the lowest, but the highest operating cost. Comprehensive analysis shows that waste heat utilization in mine should be the preferred spent scheme as a heat source alternative mining area.
