The paper introduced the application of SYZX75 wire-line coring hydro-hammer in Xiaoqinling gold ore deposit of Lingbao City of Henan Province with the application effects.The field trial results show that the unit monthly drilling effi-ciency, average hour efficiency, round trip length and core recovery rate in cracked formation are improved obviously with lower drilling cost and better protection effect of borehole deviation.
