| Abstract: | Due to complex surroundings the exta-deephole controlled blasting is required to strictly control the vibration velocity, flyrocks and collapse distance of muckpile, so it is difficult to design and implement the blasting. An extra-deep-hole controlled blasting technology is successfully put forward, and it surpasses the normal small hole and small bench controlled blasting. |
