| Abstract:Hydro-hammer drilling is an advanced technology, which can challenge hard and complex rock stratum and can improve drilling efficiency and extend bit service life; furthermore, it has better anti-inclining effect. In the exploration drilling of Tieshan mining area of Wuyang city Henan Province, percussion rotation drilling technology resolves the technical problem of drilling in the banded compound granite formation with big inclination, uneven hardness and frequent interbed. |
