Electronic detonators allow our blasters to have more control over multiple aspects of the blast, while still staying a safe distance away. Wireless remotes hooked into the blasting machine allow us to avoid stringing copper wire from the blast to the firing location like with nonel dets. We used electronics here for this 116-hole production shot. | McCallum Rock Drilling

Destroying detonators in a tunnelling project in an urban area where returning detonators to the magazine is not permitted. Number of detonators should be based on the blasting pattern to avoid any leftovers. This method is not a good practice.

The demolition of outstanding detonators in a tunnel is generally not allowed based on regulations due to the confined space, which significantly increases the risk of structural damage, entrapment, and uncontrolled explosions. Regulations typically require detonations to occur in open or specifically designed and controlled environments to ensure maximum safety and containment of the blast. Exceptions might exist only under stringent conditions and with specific safety measures and approvals fr

Stemming bucket! — Stemming is crushed stone that’s essential to effective blasting. — After the drillers have poked all the holes necessary through a rock formation, the blasters arrive to set up the shot. Using a combination of detonators for timing, high explosives, and primary explosives (usually ammonium nitrate fuel oil, or ANFO), they “load” each hole. — However, if they stopped here and let it rip, the explosive energy would choose the path of least resistance, rifling out each hole inst

💥 Controlled Blasting. What you’re seeing isn’t chaos but precision engineering. A perfectly timed multiborehole detonation used in mining and large scale excavation. Engineers drill dozens or even hundreds of blast holes, pack them with ANFO or emulsion explosives, and connect them with millisecond delay detonators. Each charge fires in a precise sequence, creating that smooth “wave” as the ground lifts. 🌊💣 The goal? Break millions of tons of rock cleanly, reduce vibration, and control the d
