Abstract

With the advancement of the information revolution, the promotion of resource development and environmental protection concepts in recent years, deep-hole bench blasting technology in domestic open-pit mines is developing rapidly under the guidance of intelligent and green blasting mining concepts. In terms of blasting equipment, a large number of electronic detonators were widely used; In terms of blasting systems, the intelligent blasting technology integrating intelligent drilling rig system, intelligent design system, explosive on-site mixing, and other technologies had taken shape. In terms of blasting technology, blasting vibration prediction theory and control, dust control, and shock wave and noise prevention, etc. have effectively controlled of the harmful effects of blasting, and gradually achieved the requirements of green blasting. Lastly, the problems in blasting equipment and blasting technology were sorted out, and the future development and research directions of green intelligent blasting in open-pit mines were pointed out.
- open-pit mine,
- deep hole bench blasting,
