20、Initiators , cap-sensitive explosives , and noncap-sensitive agents must be transported in accordance with regulations in approved vehicles，carrying classification signs. 引爆药、雷管敏感炸药、雷管非敏感剂必须按规定用许可的车辆统一运送，注意按类别标记分类搬运。 21、Proper tools for loading include a cloth measuring tape ，a wooden tamping pole， a pair of wire cutters and strippers , a mirror , grappling hooks , and a powder punch 所需装载的工具包括：一个布卷尺、一个木制捣棒、一副剪线钳和剥线钳、一把反射镜、爪钩和粉末冲击器。 22、Caps or detonating cords are inserted and wrapped around the primer in accordance with manufacturers recommendations 按照生产商提供的使用说明将雷管插入起爆物或将引爆线缠绕在起爆物上。 23、A small amount of main charge is added to the hole bottom , then（？） the primer carefully lowered. 将少量主要的炸药加到孔底部，然后将引爆物小心地缓缓放下。 24、The main charge is poured (for free-running explosives) or carefully lowered (if packaged) , while measuring the loading depth to ensure that each deck or column rises to the designed length (based on known loading density) 只要测量装载深度确保每个分层或每个孔柱的装药达到设计深度（根据已知的装药密度），就可将主要炸药倒进（散装炸药）炮眼或小心地缓缓放下（如果已经打包）。 25、Depending on the SI B ratio , the actual timing (in milliseconds) between detonating charges will determine muck pile displacement height and（or?）distance from the bench. 根据S与B的比率、荷载与起爆之间的实际时间（精确到毫秒）将会决定爆堆（石堆）的位移和高度或到平台的距离。 26、High ground vibrations result , and backbreak along the new highwall may persist , jeopardizing [d?ep?daiz] the stability of the slope. 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。 27、If interhole delays are too long , cutoffs of surface delays may occur 如果孔内爆破延迟时间太长，那么可能产生地表延时中断 28、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. 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。 29、This detachment [di‘t?t?m?nt] forms an internal free face (or relief解除) to which successive detonations（连续爆炸） will interact（相互作用） with the reflection（反射） of stress waves. 这
