How to Improve Block Stone Quality with Blasting Technology?
The extraction of block stone is a critical process in the construction materials industry, where maintaining the integrity of the material for further use is paramount. The key challenge lies in minimizing induced fracturing and surface roughness of the blocks.
🔹 Key Aspects of the Technology:
✔️ Stress wave interaction – plays a decisive role in forming the main rupture between blastholes.
✔️ Optimal charge parameters – blasthole spacing, blast product pressure, and linear charge density influence the zone of induced fracturing.
✔️ Orientation of the rupture plane – aligning it with natural fractures in the rock mass increases the yield of high-quality blocks.
🔹 Research Findings:
✔️Numerical modeling confirmed that adjusting charge parameters localizes the fracture zone.
✔️Reducing blasthole spacing while increasing charge size within limits ensures directional splitting.
