    • Abstract
  • To study the distribution of temperature field of surrounding rock-thermal insolating support system under roadway with high temperature, based on the heat dissipation of surrounding rock, the principle of conservation of energy and asynchronous long finite difference method, a one-dimensional unsteady rock-bolting system under finite difference equation was established and computer calculating program was compiled. The law of the influence of ventilation time, surrounding rock, temperature difference, heat insulation layer thickness and temperature conductivity coefficient of thermal conductivity of heat circle on the temperature field of surrounding rock has been found. The results show that the heat dissipation of surrounding rock is delayed and the disturbance of roadway air flow to surrounding rock is reduced, and the roadway cooling is accelerated:As the ventilation time increases, the confining pressure conductivity increases, the thickness of insulation layer decreases, and the thermal conductivity increases, the radius of the heat-adjusting ring increases. The temperature gradient of surrounding rock increases with the increase of ventilation time and the increase of temperature difference between wind and source rock. The cognition of heat-adjusting ring characteristics and heat insulation structure of high-temperature roadway is improved, which is helpful to arrange heat insulation support reasonably.
