Improvement of Run-through Air Reverse Circulation DTH Continuous Coring Hammer and the Test Effects
Abstract:Continuous coring technology by run-through air reverse circulation DTH hammer is mainly applied in the geological drilling in dry or water-deficient areas. In order to learn the universal applicability of this technology, a series of experiments were conducted in a water abundant mining area, by local transformation of the hammer and drill pipe, the major problems of drilling, coring and water control were solved.
