AI Technical Summary
Existing technologies have low ore extraction efficiency, poor blasting vibration effect, and insufficient safety and stability of mine structures in the calculation and optimization of deep-hole blasting block size in mines.
A VCR-based mining method was adopted. By determining the blasting parameters such as the filling length at both ends of the borehole, the amount of explosive and the delay time, and combining the water column energy absorption buffer mechanism, the active modulation of the vortex flow field and fractal theory, the blasting parameters were optimized and simulation tests were conducted to ensure safety and stability.
It improved the energy utilization rate of explosives, enhanced the blasting effect, reduced the proportion of large blocks, maximized the utilization of resources, improved ore extraction efficiency, and ensured the safety and stability of mine structures.
