Blasting Division 14 July 2026 6 min read
Excavating rock in proximity to active highways, railway tracks, or residential habitats requires specialized controlled blasting techniques to eliminate flyrock, ground vibration, and air overpressure risks.
Key Controlled Blasting Techniques:
- Line Drilling & Pre-Splitting: Creating a clean fracture plane along excavation boundaries to protect host rock integrity.
- Electronic Digital Detonators: Millisecond-range delay timing reducing peak particle velocity (PPV) ground vibration.
- Blasting Mats & Overburden Cushioning: Preventing flyrock dispersion in urban containment zones.
MERL's DGMS-certified blasting team executes controlled blasting contracts for highways, metro rail cuts, foundation trenches, and quarry benches with zero incident records.
