摘要
介绍了SYZX75型绳索取心液动潜孔锤在河南省灵宝市小秦岭金矿区的试验应用及其效果。试验结果表明,钻探台月效率、平均时效、回次长度和破碎地层岩心采取率均有明显提高,钻探成本下降,防止孔斜效果好,值得进一步推广。
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.
