ABSTRACT
The hydraulic characteristics of rock plug blasting are the key to the success of rock plug inlet/outlet construction. The hydraulic characteristics of rock plug blasting at the inlet/outlet of a pumped storage power station were studied by physical model test. The characteristics and laws of water hammer pressure, gate shaft surge and effect of rock ballast accumulation are obtained. The results verify the rationality of the design of the rock plug inlet of the project and demonstrate the feasibility of retaining water with gate directly and high-water level blasting in the process of rock plug blasting. The research results can provide technical support for the design and construction of the project and provide a reference for similar projects.
