Drilling done to fulfill the requirement that a prescribed amount of work be done annually on an unpatented mining claim to retain title.
Industry:Mining
Drilling from the surface of a body of water with a drill mounted on an anchored tower, platform, or barge.
Industry:Mining
Drilling in which a frequency of vibration in the range of 100 to 20,000 Hz is used to fracture rock. Ultrasonic drilling is one of the better known methods of vibration drilling.
Industry:Mining
Drilling operations conducted on the surface, as opposed to drilling done in underground or enclosed workplaces.
Industry:Mining
Drilling operations in which the cuttings are lifted away from the bit and transported out of a borehole by a strong current of air or gas instead of a fluid. Compare: dry running
Industry:Mining
Drilling technique that utilizes compressed air to lift the cuttings up the borehole and to cool the bit. Used when possible for environmental monitoring, because no drilling fluids are introduced into the formation. Feasible only in consolidated or semiconsolidated formations.
Industry:Mining
Drilling that utilizes longitudinal vibration corresponding to the resonant frequency of the drill string in order to "fluidize" the sediments being sampled, thereby achieving efficient penetration.
Industry:Mining
Drilling to test subsoil and rocks when considering foundations of buildings, dams, and heavy plant.
Industry:Mining
Drilling tool used in soft ground, such as overburden, clay, soft shale, etc.
Industry:Mining
Drill-rod or casing couplings to which hot rosin was applied and that were joined before the rosin cooled.
