Analysis of Wire-Line Coring Hydro-Hammer Technologies in Xiaoqinling Gold Ore Deposit

After introducing SYZX75 wire-line coring hydro-hammer, we launched the study on its assorted drilling technology and field trial in Xiaoqinling gold ore deposit of Lingbao City of Henan Province. Field trial results showed that unit efficiency per month, average hour efficiency, roundtrip length and core recovery percentage in cracked formation could be improved obviously. We also could observe the decline of drilling cost and borehole deviation. It can be further popularized.
