What are the differences between a TBM and a MTBM?

Tunnel boring machines (TBMs) and microtunnel boring machines (MTBMs) are used to construct underground tunnels and passages with circular cross-sections. They both use a drilling mechanism, known as a cutting head, to remove material and advance the equipment forward. However, both these…
