Application Effect of SYZX96/75 Wire-line Coring Hydro-hammer

Abstract:

The paper introduced the application of SYZX96/75 wire-line coring hydro-hammer in complex formation with interbedding of soft and hard rocks in a gold mine of Hunan and summed up the construction experience. SYZX96/75 wireline coring hydrohammer was applied with the footage greatly increased and auxiliary time reduced, which played a key role in improving the coring effect in broken formation and reduced hole deviation.

Key words:wire-line coring; hydro-hammer; complex formation with interbedding of soft and hard rocks; drilling
