Fracture plane control in rock blasting |
|
| Authors: | Wu Li Zhang Shizhong Chen Jianping |
| Abstract: | Blasting operation dissipates much of the blasting energy in crushing the rock at the borehole and the resulting cracks are randomly oriented. There is very little control of the fracture plane. In order to control the fracture plane, many methods have been applied. This paper discusses a new blasting method in which a high degree of fracture control can be achieved while minimizing the ground shock. |
