| 中文摘要: |
| 磷矿在传统农业以及化工业需求旺盛，并随着工业迭代升级，在新能源产业中的需求也日益增加。在浅部易开采磷矿减少的当下，深部磷矿的开发具有重要意义。贵州是中国磷矿资源的主要存储省份，其磷矿具有品位高储量大的特点，但由于贵州是易受深部溶蚀带和破碎带影响的喀斯特地区，对该地区的磷矿竖井安全布置提出较高要求。针对该类矿区岩溶构造多、导水性强、构造边界模糊等问题，本文综合运用高密度电法和扩频激电法进行磷矿竖井选址应用研究。通过对反演的电阻率及幅频率图像圈定低阻槽状高风险区域，结合了两种方法的优势，并且相互验证，从而提高磷矿竖井选址的安全性，为下一步磷矿开采提供有效参考意见。 |

| Phosphate ore is an important mineral resource with high demand in traditional agriculture and thechemical industry. With ongoing industrial upgrading, its demand in the new-energy sector has also increasedsteadily. As easily accessible shallow phosphate rock reserves are decreasing, the development of deep phosphate rock is of great significance. Guizhou Province is one of the major phosphate resource bases in China, characterizedby large reserves and high ore grades. However, as Guizhou is a typical karst region where deep strata are stronglyaffected by dissolution zones and fractured belts, stringent requirements are imposed on the safe layout of verticalshafts in phosphate mining. To address the challenges of widespread karst structures, strong groundwater conductiv-ity, and poorly defined structural boundaries in such mining areas, this study applies high-density electrical resistiv-ity imaging in combination with broadband induced polarization for shaft site selection. By delineating low-resistance trough-shaped high-risk areas through the inversion of resistivity and phase images, and the complemen-tary advantages of the two methods are integrated and mutually validated. This joint approach enhances the safetyand reliability of phosphate mine shaft siting and provides effective geophysical guidance for subsequent phosphatemining operations. |
