Tunnelling in rock using the drill and blast method is a well-established technique that involves drilling a series of holes into the rock face, loading them with explosives, and then detonating them to break the rock into manageable pieces. This method is particularly effective in hard rock conditions, allowing for precise control over the excavation process. Our Online Tunnel Engineering course offers an in-depth exploration of the drill and blast method, along with a comprehensive overview of

Tunnel Boring Machine (TBM) construction is a mechanized tunnelling method used for excavating underground tunnels with minimal surface disruption. A TBM is a massive cylindrical machine equipped with a rotating cutterhead that excavates soil or rock while advancing forward. The excavated material is transported out of the tunnel via conveyor belts muck transportation or slurry pipelines, depending on the TBM type. Simultaneously, pre-cast concrete segments are installed along the tunnel walls t

The New Austrian Tunnelling Method (NATM) is a versatile and innovative approach adaptable to a wide range of geological conditions. It can be effectively applied in soft ground, soft rock, or hard rock environments. The method involves excavating tunnels in small sections and immediately supporting them with shotcrete, steel ribs, and wire mesh to strengthen the structure. At MEIL Group, we adopt NATM to deliver vital tunnel projects across the country, ensuring world-class infrastructure is bu
