| Abstract: |
| In excavation of steep rock, a method of combining horizontal-hole springing blasting and shearhole springing is used, so as to reach a fastened construction schedule, a reduced blasting costs as well as a safety operation in terms of the control of the slope height in reasonable level. The difference of hole springing, hole loading and applicable condition are given by contrasting horizontal-hole springing blasting with shear-hole springing blasting. |
