Drill and Blast Tunnelling
The continuous development of equipment, particularly for drilling, and the development and improvement of explosives helped drill and blast to achieve a considerable significance. The hardness, toughness and strength of the rock to be drilled determine the requirements for the drilling tools. In drill and blast tunnelling, clearance of the muck lies on the critical path, which means that each minute saved here shortens the round cycle and thus the overall construction time. After discussing the processes of drilling, blasting and mucking, and highlighting the effects of blasting on the surroundings, this chapter describes some possibilities of the combinations of drill and blast with mechanised tunnelling for larger cross‐sections. The chapter also discusses mechanisation and automation issues which can simplify the tasks of people or reducing exposure to harmful actions during their work.
