| Abstract: | Using geological structure survey method,it found out the diamond-shaped body which be made by structural plane cutting in crack mass,and determined the diamond-shaped body shortest axis direction with the direction of burden for rock blasting.This method had been applied to mine production,and improved the blasting effect obviously,it can make a guide to determine the direction of burden in crack mass for blasting other similar engineering. |
