摘要
单自由面条件下,作用在被爆破介质上的最有效破坏力小,而阻碍介质破坏的作用力却很大,为了使爆破取得应有的效果,必须加强炮孔的堵塞。
Under single free face condition, the best valid breaking force on the blasted medium is very weak,and the force impeding the fracture of medium is quite strong .In order to get a due blasting effect,must strengthen to plug blastholes.
