| Abstract: | Yongping copper mine has entered into deep open-pit mining phase after these years mining. High and steep slope has been formed. The influence of blasting near slope on the safety and stability of high and steep slope is increasingly obvious. Through analyzing the slope explosion principle, the blasting parameters of large diameter vertical hole was confirmed and the feasibility of large diameter vertical hole in slope controlled blasting was demonstrated On the basis of present drilling facilities and blasting practice. |
