| 针对老旧矿区历史勘查数据与现代空间基准不统一引发的储量定位模糊、数据可信度不足等问题，本研究构建了“基准统一—数据整合—复核校正—偏差归因”的系统性复核技术体系，集成坐标异构转换、历史图件配准、多源数据融合及空间拓扑检查等关键技术。以云南某磷矿区为例，系统实施了平面坐标系、高程基准及资源储量数据的一体化复核。结果表明：转换后地质图件平面中误差优于±7.0 m，高程中误差优于±1.0 m，均满足规范限差；通过空间叠置分析，厘清了多期储量范围与矿权范围的矛盾，发现范围重叠、消耗量归属不清等问题，并核减未利用资源量5900 t。该体系可有效提升老旧矿区空间数据精度与一致性，为资源储量精准管理和矿权数字化治理提供技术支撑。 |

| To address the issues of ambiguous reserve positioning and insufficient data credibility caused by the inconsistency between historical exploration data and modern spatial datums in legacy mining areas， this study establishes a systematic review framework following the workflow of “datum unification — data integration — verification and correction — deviation attribution”. Key technologies integrated include heterogeneous coordinate system transformation， historical map registration， multi-source data fusion， and spatial topological checking. A phosphate mining area in Yunnan Province is taken as a case study， where a comprehensive review of the planar coordinate system， vertical datum， and mineral resource and reserve data is carried out. The results show that after transformation， the mean square error of plane coordinates is better than ±7.0 m， and that of elevation is better than ±1.0 m， both meeting the specified tolerances. Through spatial overlay analysis， spatial conflicts between multi-period reserve estimation boundaries and mining right boundaries are clarified， revealing issues such as boundary overlaps and unclear depletion attribution， and reducing the unutilized resources by 5.90 kt. The proposed framework effectively improves the spatial accuracy and consistency of legacy mining area data， providing technical support for precise resource and reserve management and digital governance of mining rights. |
