| 中文摘要: |
| 深部找矿是近年来地质勘查领域的热门话题，上宫金矿田累计查明金资源量已突破100 t，且矿床深部仍有巨大的找矿潜力。通过分析，优选在F1断裂与Ⅴ号断裂带的交汇部位（干树第10勘探线深部）实施了孔深2002.72 m的熊耳山地区第一深钻。深钻采用XY-8型钻机、深孔绳索取心钻杆、孕镶金刚石钻头、SG24A四角钻塔、BW320型泥浆泵，以Φ150口径开孔、经两次变径至Φ75口径终孔，浅部套管护壁，小规模破碎带选用高分子聚合物护壁，F1主断裂带采取硫铝酸盐水泥护壁堵漏，经3次空洞事故成功处理，平均台月效率254.58 m/台月，高质量完成了钻探任务。深钻的实施为该区域深部找矿打开了广阔的空间，有效解决了区域勘查深度不足、深部找矿前景不明的问题，对区域开展深部钻探工程施工具有一定的借鉴意义。 |

| Deep prospecting has been a hot topic in the field of geological exploration in recent years. The cumulative amount of gold resources identified in Shanggong gold orefield has exceeded 100 tons， and there is still great prospecting potential in the deep part of the deposit.Through geological analysis， the first deep drilling in Xiongershan area with a hole depth of 2002.72 m was preferably carried out at the intersection of F1 fault and V fault zone （the deep part of Ganshu 10th exploration line）.XY-8 drill rig， deep hole rope coring drill pipe， impregnated diamond bit， SG24A quadrangle drill rig and BW320 mud pump are used in deep drilling. The hole is opened with Φ 150 diameter and the diameter is changed to Φ75 diameter end hole twice. The shallow casing protects the wall， the small-scale fracture zone adopts high molecular polymer to protect the wall， and the F1 main fracture zone adopts sulphoaluminate cement to protect the leakage. after three cavity accidents， it is treated successfully.Average monthly efficiency 254.58 m/monthly， high-quality completion of drilling tasks. The implementation of deep drilling has opened up a broad space for deep prospecting in this area， effectively solved the problems of insufficient regional exploration depth and uncertain prospects for deep prospecting， and has a certain reference significance for the construction of deep drilling projects in the region. |
