| 中文摘要:在陇南紫金李坝金矿钻探施工中遇强水敏性、破碎、复杂地层，普通绳索取心钻具岩心采取率低，平均采取率86.5%，回次进尺少，多在1 m以下，最小回次进尺只有20～30 cm，钻进效率低，平均台班进尺约5 m。通过使用SYZX96型绳索取心液动锤，钻进效率明显提升，平均岩心采取率提高8%，平均回次进尺提高50%，平均台月效率提高17.5%，纯钻时间增加到了60%左右。共完成6个钻孔，进尺2488 m，其中2个钻孔采用SYZX96型绳索取心液动锤，效果明显。总结出适合强水敏性、破碎、复杂地层绳索取心液动锤的使用经验，为类似地层钻探施工提供技术借鉴。 |

| Abstract:Strong water sensitive and broken formation was encountered in drilling construction in Liba gold mine of Southern Gansu, drilling by ordinary wire-line coring tool resulted in low core recovery and low drilling efficiency, the average core recovery rate was 86.5%, the footage per run was below 1 meter, the minimum was only 20～30cm and the average footage per team was about 5 meters. Good drilling efficiency has been achieved by using SYZX96 wire-line coring hydro-hammer, the average core recovery rate, average footage per run and average machine efficiency per month have been improved by 8%, 50% and 17.5% respectively; drilling time increased to about 60%. Based on the application situation, the paper elaborates SYZX96 wire-line coring hydro-hammer about its structure, working principle and the points for attention in operation. |
