This blasting high-energy tube achieves directional energy release through the cumulative energy effect, featuring the following advantages:

1. Increase Blasting Efficiency: The convergent structure boosts crack propagation length by three times, allowing blast depth up to 3.7 meters, with each cycle saving about 50 minutes of labor.

2. Crack Control Precision: Directional accuracy of cracks is controlled within 2°, minimizing damage to the surrounding rock mass.

3. Cost Reduction: Reduced explosives usage, with the shaped charge tube structure concentrating explosive energy release, which can save approximately 20% of explosives compared to traditional blasting methods.

4. Reduced number of blast holes: The spacing between peripheral holes can be expanded to 80cm, reducing the number of blast holes by 20-25, thereby lowering labor costs.

5. Safety Assurance: Precision blasting control minimizes the impact of flying debris and vibrations on surrounding buildings and personnel, enhancing operational safety.

6. Overbreak Control: Post-blast contour lines are more even, reducing overbreak and underbreak occurrences, and lowering the amount of shotcrete needed later.

7. Environmental Features: Dust reduction, water bag structure creates a "water wedge" effect during explosion, minimizing the spread of harmful dust.
