| Abstract: | In this paper, the test of blasting stress wave in open pit mine was adopted, and the peak stress and tensile stress peak were calculated based on the collected wave. Then combining with the theoretical analysis, field test and other methods, the stress wave in the process of explosion was studied the 3DMine - Rhino - ANSYS. The basic law of stress wave propagation in the blasting of cylindrical charging step blast-hole was analyzed, and the attenuation law of stress wave under the condition of cylindrical charge in open pit mine was obtained. |
