Abstract:Taking advantage of incompressibility and dust-suppression properties of water, the hydraulic blasting technology has attracted attention of the blasting industry since it was used. In view of the difficulty in mastering the application points and its unsatisfactory effect, the technology has not been applied widely. After technical modification, this technology is put into several practices of limestone for cement, and a hydraulic blasting technology scheme suitable for the mine is developed. It serves as a reference for cost reduction, ore fragment size balance and dust suppression of mine blasting in the same industry.
