通风时间对围岩温度场的影响主要表现在2个方面:一是随着通风时间的增加巷道围岩温度逐渐降低,并且降低的速率随着通风时间的增加逐渐减小;二是随着通风时间的增加巷道围岩内部的温度影响范围逐渐往围岩深部扩展,巷道围岩冷却范围与通风时间的平方根成正比。
Ventilation time on the surrounding rock temperature field mainly in two aspects: First, as the ventilation time increases the surrounding rock temperature gradually decreased, and the rate of decrease with the increase of ventilation time gradually reduced; the second is with the ventilation The increase of time The temperature influence range of the surrounding rock gradually expands to the deep surrounding rock. The cooling range of the surrounding rock of the roadway is proportional to the square root of the ventilation time.
