How Controlled Blasts Actually Work 💥

Ajouté : 2026-06-01

[00:00:03]This is called control blasting. And the reason the explosion travels so smoothly across the ground is because every charge explodes at a slightly different time. Engineers place hundreds of explosives inside drilled holes. [music] Then they connect everything with time detonators. Some of those delays are literally measured in milliseconds.

[00:00:20][music] The goal isn't just to blow up rock, it's to control where the energy goes.

[00:00:25]If everything [music] explodes at once, the blast could damage nearby structures and waste huge amounts of energy.

[00:00:31]Instead, the explosions move forward in sequence, breaking the rock apart step [music] by step, almost like dominoes.

[00:00:37]And the craziest part is that some destination quartz [music] can send the explosion signal at nearly 1.2 miles per second. That's why the blast looks like it's racing across the ground.
