摘要
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 efficiency,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.
