Abstract:

When performing mine blasts, physical-mechanical parameters of the rock in the blasting area are very important information. It directly affects the choice of solution and blast parameters. Apply numerical analysis methods of using a database of shock waves after each explosion to determine the propagation velocity of the shock wave can help to describe somewhat the image of the geological structure of the explosion area. This paper introduces the application of techniques to analyze shock wave data obtained from delay blasting at Hong Son limestone quarry, Kim Bang, Ha Nam. The analysis was performed using Matlab software with digitized data. The analytical results are described in detail in the paper
