| Abstract: | Preserved dike construction method is usually adopted in rock blasting near structures.In view of Antuoshan project,deep-hole controlled blasting excavating technique of the preserved dike was introduced.Some parameters were put forward such as the thickness of preserved dike,principle of hole arrangement,charging requirement,protection system and so on.When the preserved dike was excavated by the technique,it could ensure excavation safety,speed up excavation progress,and reduce excavation cost. |
