孔塞是在地震放炮完毕后用来堵住炮洞或井洞的设备。通常需要把孔塞推到足够的深度来防止它松动,然后再加土掩埋至与周围地表齐平。也称桥塞。孔塞也可以用在钻井操作和引爆炸药之间的间隔临时关闭炮洞。

A device used to plug a shothole after shooting. Usually the plug is pushed far enough into the hole to prevent it is being dislodged and earth is shoveled over it level with the surrounding ground. Also called bridge plug. Hole plugs are also used to close shotholes temporarily between the drilling/loading operation and the detonation of the charge.
