  • Drilling and blasting Wikipedia

    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 often known as a rock

  • Rock Boulder Blasting with Explosive
    BlockholingSnakeholing Or BombingMudcappingBlasting MatsBlockholing is the placing of an explosive into a shallow drill hole in a boulder. Tamping the explosive makes better use of the explosive’s energy, provided there is sufficient stemming material in the hole. Upon detonation, the explosive energy produces radial cracks about the drill-hole caused by shock waves. The radial cracks are then expanded by gases from the explosive’s chemical reaction. Increased efficiency over other methods can be achieved by the lesser amount of explosive needed t...
