A drifter drill, sometimes called a rock drill, is a tool used in mining and civil engineering to drill into rock.Rock drills are used for making holes for placing dynamite or other explosives in rock blasting, and holes for plug and feather quarrying.. While a rock drill may be as simple as a specialized form of chisel, it may also take the form of a powered machine.

Longhole. This method consists in a variety of chambers where the mine blocks are generally cut by sub-levels from which long holes are drilled in plans that are generally parallel. These boreholes allow to blast the block by successive vertical break. The broken ore is mucked out by drawpoints or by longitudinal retreat.

Long hole rods are available in male-male and male- options.Drilling with the minimum possible hole deviation is important for more consistent fragmentation, increased efficiency, and reduced operational costs.
Drifter Conversion Programs
Drifter conversion highlights: Wide range of drifters and cradles make adaptations simple for virtually all drills, regardless of manufacturer. Results in up to 10% higher penetration rates, which results in faster drilling times and increased productivity. Increases bit life by up to 47% and shank life up to 60%.
mining - mining - Blasthole stoping: When the dip of a deposit is steep (greater than about 55°), ore and waste strong, ore boundaries regular, and the deposit relatively thick, a system called blasthole stoping is used. A drift is driven along the bottom of the ore body, and this is eventually enlarged into the shape of a trough. At the end of the trough, a raise is driven to the drilling ...

Underground hard-rock mining
Underground hard-rock mining refers to various underground mining techniques used to excavate "hard" minerals, usually those containing metals, such as ore containing gold, silver, iron, copper, zinc, nickel, tin, and lead also involves the same techniques used to excavate ores of gems, such as diamonds and rubies. Soft-rock mining refers to the excavation of softer minerals, such as salt ...

undercuts can be prevented by systematically bolting these cuts. The proposed mining method is cut-and-fill stoping, which technically is the same as longhole open stoping with delayed backfill that is currently being used. The maximum width of the longitudinal stopes should be increased from 7m to 10m. Stope length and level height
