的位移和高度或到平台的距离。Р26、High ground vibrations result , and backbreak along the new highwall may persist , jeopardizing ['dʒepədaiz] the stability of the slope. Р地表强震的结果,可能会产生沿未采工作面的超爆,危害边坡的稳定性。Р27、If interhole delays are too long , cutoffs of surface delays may occurР如果孔内爆破延迟时间太长,那么可能产生地表延时中断Р28、The minimum time for design is controlled by the stress wave travel distance in order(整齐、有序) for radial cracking to begin to develop , contributing to the detachment(分裂) of the rock mass in the vicinity (在……附近)of the bole.Р设计的最小延时是由应力波的扩散距离决定的。这扩散是从放射状裂隙开始向四周发展的,这有助于分裂孔周围的岩石块。Р29、This detachment [di‘tætʃmənt] forms an internal free face (or relief解除) to which essive detonations(连续爆炸) will interact(相互作用) with the reflection(反射) of stress waves.Р这种分裂(沿着连续爆炸的方向)形成(或解除)一个个内部自由面,这种连续爆炸将会与应力波的反作用相互作用(共同分裂岩石)。
