Drilling and blasting is the controlled use of explosives and other methods such as gas pressure blasting pyrotechnics, to break rock for excavation. It is practiced most often in mining, quarrying and civil engineering such as dam, tunnel or road construction. The result of rock blasting is

The company’s mine plan calls for the addition of large, mechanised mining equipment, including 14 ton and 17 ton load-haul-dump machines, and 50 ton haul trucks to support the planned long-hole mining method. ‘Mechanisation works in greenfield sites and it is the future, but feasibility depends on the mine design,’ says Vogt.

The bord and pillar mining method is employed and stoping widths average around 2m. Mining bords advance along the strike. The mining cycle involves mechanised support drilling and installation, mechanised face drilling, charging and blasting, and mechanised lashing onto a conveyor network to an underground bunker.

2.1 Drill and blast mechanised tunnelling and development 2.1.1 Drop raising Drop raising, also known as “longhole raise blasting” or “upsidedown raising”, is an excavation which is completely pre-drilled over its full length, then charged from the top, or bottom, and finally blasted from the bottom in practical
