Testing Method for the Range of Fracture Zone of
2021-6-7 · Based on the field blasting test and the numerical simulation presented in this study, the following conclusions can be drawn: (1) Based on the closeness between the transmission coefficient of the stress wave through the test rod-rock interface and the ratio of the dynamic compressive strength of the test rod to the dynamic tensile strength of the rock, the fracture range of the test rod after blasting can be used as the range of the surrounding rock …
