摘要
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。
The influence of ventilation time to the temperature of surrounding rock affects two parts.One is as the increase of ventilation time,the temperature of surrounding rock and the decrease rate gradually decreases.The other is as the increase of ventilation time,the cooling range of surrounding rock extend to the deep,and the cooling range is proportional to the square root of ventilation time.
