爆破岩石

Clashing Rocks───碰撞岩石

blasting off───点火起飞；发射升空（等于blast-off）

blasting out───爆破

casting rods───铸棒

floating docks───n.浮动船坞

roasting jacks───烘烤千斤顶

blasting powders───爆破药粉

Taking two actual blasting projects as an example, precautions against flying rocks, which are taken aiming at the concrete conditions, are introduced.───以两个实际爆破工程为例，介绍了针对具体情况所采取的飞石防范措施。

For this purpose, the causes for flying rocks are analyzed and the sorts of flying rocks are studied based on the theory of rock fragmentation by blasting and the field investigation.───为此，根据爆破破岩理论和现场调研，分析了飞石产生的原因，讨论了飞石的类型。

The blasting efficacy of break rocks by water coupling charging and explosive coupling charging is discussed in the paper. A few conclusions of significance are gotten.───从理论上对水介质偶合装药爆破与炸药偶合装药的破岩效能进行了讨论，得出一些有意义的结论。
