Abstract

In order to prevent air and soil pollution caused by spontaneous combustion of gangue dump, avoid landslide, explosion and other disasters, and fundamentally solve the problem of spontaneous combustion of gangue dump, based on the principle of heat pipe phase change heat transfer, the effect of group tube spacing and tube type combination on the cooling effect was studied through the field group tube test of gangue dump. The results show that the group pipe has a significant cooling effect on spontaneous combustion coal gangue dump. Within 100 days, the maximum drop value of monitoring site is 91 ℃, and the average drop value is 0.91 ℃/day. The arrangement of group pipes with spacing of 4 m in the high temperature area can control the spontaneous combustion temperature rise and keep the temperature falling steadily. The arrangement of group tubes with spacing of 5 m in the middle temperature zone can inhibit the oxidation temperature rise, and it is necessary to appropriately change the arrangement spacing in some higher temperature zones to achieve more efficient cooling. Group tubes with spacing of 6 m in the low-temperature zone can prevent temperature rise and spontaneous combustion in the low-temperature zone. The location of heat pipe evaporation section is the best cooling depth of gangue dump, and the alternate arrangement of long and short pipes can avoid the heat transfer process caused by the shallow layer temperature rise, which is conducive to the comprehensive temperature control and fire extinguishing of gangue dump.
