If a hole is drilled, the pressure can be reduced in the hole and thereby in the rock section adjacent to the hole.
如果一个井孔钻成，井内压力就要下降，井孔附近岩体内的压力也跟着下降。

In some cases the difference in atmospheric pressure causes the air to circulate naturally; in others a fan must be used to pump air into the mine.
有些矿井利用大气压力差引起空气自然流动，有些矿井则必须用扇风机把空气压人井内。
