Optimization of Smooth Blasting Parameters for the Over-flow Tunnel of Wustong Reservoir
The overflow tunnel of Wustong Reservoir adopts smooth blasting technology.After multiple designs and adjust-ments of excavation methods and blasting design parameters,a rea-sonable blasting plan has been determined,effectively solving the problem of under excavation.While improving the half hole rate of smooth blasting,it also shortens the working cycle and increases the engineering efficiency.
