What is Excavation Technologies in Tunnelling about?
Conventional tunnelling involves excavating a tunnel in small increments and installing support as work progresses. It can be done using either full-face or partial-face excavation. Partial-face excavation uses techniques like top-heading and bench excavation. Drill-and-blast excavation involves drilling blast holes, charging them, blasting, ventilation, scaling loose rock, and mucking out debris using loaders and haulers. Other conventional excavation methods include using hydraulic or pneumatic hammers.
