Dirty Great Machines

Take a trip underground and get up close and personal with titans of tunneling: the biggest, baddest tunnel boring machines on the planet. These monsters dig deeper and faster than ever before, gouging holes in the Earth's crust for subways and sewers.

Get dirty with the monsters of mining. These building-sized behemoths cut, scrape, blast, and dig through dirt and rock to get to the most precious minerals on the planet.

Dive deep underwater and marvel at these maritime monsters. These huge drill ships and jet trenchers transform the bottom of the world's oceans, extracting precious oil and laying international cable to support our huge global economy.

In Canada, almost two miles underground in the world's deepest copper and zinc mine, a mighty drill chews through rock, digging deep holes which are then filled with explosives and detonated, leaving behind debris packed with valuable minerals.
