| 中文摘要: |
| 新疆喀拉通克铜镍矿自1989年建成投产，已生产27年，属中度危机矿山。为探测该矿山深部资源，需要提供地质构造和隐伏含矿岩体的信息，为此开展了地震数值模拟和高精度反射地震研究。地震正演模拟结果为该区金属矿地震数据采集观测系统设计和实际地震资料的解释提供了依据，地震勘探获得的反射地震剖面分辨率高，成像清晰，能够对测区深部地质结构和构造及隐伏岩体进行可靠解释。地震剖面的地质解释得到了钻探验证，证实了深部含矿岩体的存在。该地震探测结果为在矿山寻找深部隐伏矿指提供了线索。 |
| 英文摘要: |
| The Karatungk Cu-Ni deposit mine was built in 1989, which has been exploited for 27 years, and is in a moderate crisis at present. For detecting the deep resources of this mine, it is necessary to acquire the information of relevant geological structures and concealed ore-bearing rock bodies in the subsurface. So we have carried out the seismic numerical modeling and high-precision reflection seismic profiling in this area. The results of the seismic forward modeling provided a basis for the design of the seismic data acquisition system and interpretation of real seismic data. The seismic profile conducted has a high resolution and clear images, permitting reliable interpretation of the deep geological structure and concealed rock bodies. The interpretation of seismic data has been verified by the drilling, confirming the existence of the ore-containing rock bodies at depth. The seismic exploration results offer clues for the further prospecting of deep concealed deposits in this mine area. |
