Bored tunneling is a method used to create underground tunnels without disturbing the surface above. This technique involves using a specialized machine called a tunnel boring machine (TBM) that drills through soil and rock, removing material as it advances. The excavated material is transported away, allowing for a smooth and efficient tunneling process. This method is often employed for constructing subways, sewers, and utility tunnels. Bored tunneling minimizes surface disruption, making it ideal for urban areas where maintaining traffic and infrastructure is crucial. It also reduces noise and vibration compared to traditional tunneling methods.
