    • Abstract
  • The amplification effect of slope elevation in mine blasting engineering seriously affects production safety of open-pit mine. Based on the blasting vibration test in Hequ Old County Open-pit Mine, we use MATLAB to carry out linear regression analysis for the test data, and compare the calculated data and experimental data. By studying the change laws between relative error and elevation, the results show that the peak of particle vibration velocity amplification effect will appear when measuring point elevation reaches a certain value. Finally, we use the improved Sodev’s empirical formula to forecast mine blasting vibration.
