摘要(Abstract)：
针对万吨级船坞坞口岩坎爆破范围宽度大、纵深长、厚薄不均等特点，采用了不同常规的水下爆破方法，即超深缓倾孔法，达到坞口岩坎一次爆除的目的。本文对该方法从设计到施工进行了全面总结。
The underwater rock dam to be blasted at the entrance of a 10000t shipyard is very deep and wide with varying thickness. In light of these characteristies,an untraditional underwater controlled blasting technology of superdeep and gently inclined hole is adopted,and the goal of once blasting removal of the rock dam has been achieved.The paper summarized the blasting method involving design and construction.
