Students are to undertake a tunnel blast design for the following conditions:
• Tunnel is 5.5m wide by 5.5.m high
• Rock is a granite with a UCS of 300 MPa
• Drill hole diameter is 51 mm, hole length is 4m
• The cut is to contain 2 relief holes of 75mm diameter
• Dry conditions are anticipated, ANFO to be used with a density of 800 kg/m3 and a powder factor of 0.6 kg/m3
• Nonel detonators are to be used
