摘　　要：攀西钒钛磁铁矿区深部及外围普查项目实施中,在破碎、坚硬、打滑地层钻进及大断层、断层破碎带穿越,使用普通绳索取心钻进,施工周期、效率、效益都受到严重影响。项目组尝试多种新型钻进技术工艺及技术关键,2013年优选国土资源部勘探技术研究所研制的SYZX96和SYZX75绳索取心式液动锤,集绳索取芯与液动冲击回转钻进为一体,在坚硬"打滑"地层和破碎地层中具有钻进效率高、钻孔质量好、岩芯采取率高、钻探成本低,钻进技术工艺等方面取得了突破性进展,达到了预期目的,值得推广。Production Test of SYXZ wire-line coring hydro-hammer carried in Yanbian, Hongge, Lanjian and Zhujiabaobao ore districts and so on in 2013 has achieved good results. Integrating the wire-line coring with the hydraulic impact rotary drilling, The SYXZ wire-line coring hydro-hammer is characterized by high drilling efficiency, good drilling quality, high core recovery rate and low drilling cost in drilling in hard-"slip" formation and fractured formation.
