The average coal gangue accounts for about 20 percent of the mining amount, the comprehensive utilization rate of the coal gangue in China is about 30 to 40 percent at present, and most of the coal gangue is piled nearby as waste to form coal gangue hills which have different sizes, occupy land and destroy landscapes. According to statistics, 5000 more gangue dumps exist in China, and about 1/3 gangue dumps generate spontaneous combustion with different degrees. Spontaneous combustion of the coal gangue dump, ashing of organic matters and dissociation and volatilization of sulfur are carried out, so that the stability of the coal gangue dump is poor, and geological disasters such as collapse, landslide, debris flow and the like are easily formed when the coal gangue dump is eroded by artificial excavation, explosion or heavy rain. Spontaneous combustion of the coal gangue causes serious pollution and great damage to the ecological environment and landscape of a mining area, and causes other related social problems and environmental problems. The pollution of atmosphere and water body caused by toxic gas generated by spontaneous combustion of coal gangue is the most serious, and the health of local residents is also influenced. Therefore, the treatment of the coal gangue dump is a practical problem to be solved urgently in ecological environment treatment and sustainable development of the coal mining area.

At present, the existing waste rock hill is mainly treated by a grouting fire extinguishing mode, and the mode can play a good effect in the middle and later stages of spontaneous combustion. In the early stages of spontaneous combustion, there are no combustion points inside the mine. However, over time, the interior of the mine slowly burns due to the gradual increase in temperature and supply of oxygen within the mine. If can carry out effectual cooling to the hillock, then just can avoid the hillock spontaneous combustion. Meanwhile, a large amount of monitoring equipment on the coal gangue dump needs to supply power, and a new research direction is provided for how to fully utilize the heat energy of the gangue dump to generate power.
