Application of Tunnel Boring Machines in Underground Mine
tunneling projects is now carried out by mechanical excavation rather than drill and blast methods. Drill and blast is also a well developed technology, and the choice of excavation method becomes a matter of economics for both civil construction and mining. Faster development schedules and lower costs can be achieved with mechanical excavators

This method is also known as the New Austrian Tunnelling Method (NATM). The excavation location of a proposed tunnel is divided into segments first. The segments are then mined sequentially with supports. Some mining equipments such as roadheaders and backhoes are commonly used for the tunnel excavation.
