Abstract

In order to reduce the impact of blasting shock waves on underground personnel and equipment, studies were conducted by using the NUBOX-9012 intelligent blasting shock wave monitor and the matched shock wave sensor to monitor the explosion shock wave on site and using the finite element software ANSYS/ LS-DYNA to simulate the attenuation process of blasting shock waves on the straight-through roadway. The results of numerical calculations were extracted, the unknown coefficients b1, b2, and b3 in the formula for shock wave peak overpressure prediction on straight-through roadways with one end opening were acquired, and the calculated value was obtained by substituting the original data of different doses at different distances into the prediction formula as compared with the measured value. The results show that the prediction error is within reasonable limits, and the prediction formula are applicable to the prediction of the peak overpressure of shock waves on straight-through roadways. © 2019 China Safety Science Journal
