Numerical Analysis of the Ground Vibration Isolation of Shock Wave Propagation under Blasting in NuiBeo mine, Quang Ninh

This paper introduces a technique of numerical analyzing shock wave data obtained from delay-time blasting to determine wave propagation velocity. This is one of the parameters that indirectly describe the rock physical -mechanical property. The results of experimental application in Nui Beo coal mine area have confirmed the feasibility of the solution.
