How Tunnel Boring Machines Drill Through Solid Rock | How Machinery Works

How do engineers build massive tunnels hundreds of feet beneath busy cities without causing the ground above to collapse? In this video, we go inside a Tunnel Boring Machine (TBM) and reveal how these enormous machines cut through solid rock, remove millions of tons of material, install concrete tunnel linings, and precisely steer underground. From powerful cutterheads and hydraulic systems to conveyor belts and advanced pressure monitoring, discover how engineers transform solid ground into massive underground tunnels.
