| Abstract: | The influence of blasting impact load on the mechanical properties of wall rock or retaining rock are studied. A laboratory mold using drill sampling method is used to study the damage extension of different positions in retaining rock by blasting. Through the test of compressive strength and ultrasonic examination of the damaged rock, the damage extension in the retaining rock can be calculated to predict the situation in the retaining rock after blasting. A calculating method is presented to calculate the damage extension of the retaining rock. |

| Keywords: | retaining rock mechanical property blasting ratio distance |
