Abstract: The blasting cost accounts for about 30% of the mining cost of open-pit mines，and the blasting quality will significantly affect the subsequent loading，transportation and crushing costs.Therefore， it is of great significance to reduce the blasting cost for mining enterprises.Through in-depth analysis of the current status of China's blasting operation cost management，there are problems such as weak cost manage‐ ment awareness，poor management level and imperfect supervision mechanism. At the same time，the influ‐ encing factors and difficulties of blasting operation cost control are analyzed in detail.On this basis，the key measures of blasting cost control are summarized，including the optimization of blasting design parameters， the application of intelligent blasting technology and the effective management of the cost of civil explosives. Finally，the future development trend of the blasting industry is prospected，and it is pointed out that the blasting technology innovation is still the core measure to control the blasting cost，especially the intelligent blasting technology. With its significant advantages in improving efficiency and precise control，it will be‐ come the dominant direction of the future development of blasting engineering technology.
