| Abstract: | A numerical calculation model of deep-hole water pressure blasting was established by the Nonlinear Dynamic Analysis finite element program LS-DYNA. The conclusion that deep-hole water pressure blasting may thrift charges was verified through comparing the numerical simulation results with the results using approximate acoustical formula. |
