Complex orebodies often exhibit intricate geometries, extensive branching and fault truncation, and the traditional practice of manually stitching wireframes one by one is inefficient and highly subjective. This paper proposed a refined and efficient modeling strategy tailored to complex orebody geometries. It formalized a signed distance field (SDF) definition and an efficient construction method based on contour lines, and implemented a hierarchical workflow—multi-wireframe automatic one-step modeling, local wireframe correction, and sporadic extrapolation modeling—that balanced automation with boundary fidelity. The method was validated on a structurally complex concession in the Democratic Republic of the Congo using the DIMINE platform. The overall modeling cycle was reduced from 230~440 h to 46~67 h. Over 170 mineralization models (≈1.91×10⁷ m³) and more than 180 orebody models (≈1.31×10⁷ m³) were successfully produced. Obtained models passed closure and topological validity checks with controllable errors. Results demonstrated that the proposed approach substantially improved automation for complex orebody modeling while retaining geometric accuracy at local mutation zones via secondary repairs, and thus offered a general technical path and implementation scheme for similar complex deposits.

复杂矿体通常具有几何形态多变、分支多、断层相互切割等特征，针对这类复杂矿体矿山的设计，传统逐条手工拼接线框的二维绘图方式存在效率低、主观性强等问题。为此，本文基于矿体轮廓线距离场构造与轮廓线拼接法，提出一种可兼顾自动化与边界精度的“多线框自动一次建模—局部连线框修正—零星外推建模”的高效建模方法。以刚果金复杂矿区为工程示例，经DIMINE平台验证，建模周期由传统方法的230~440 h缩短至46~67 h，同时成功构建了170余个矿化模型（约1.91×10⁷ m³）与180余个矿体模型（约1.31×10⁷ m³）。封闭性与拓扑有效性检测表明，模型误差在可接受范围。该方法既提高了复杂矿体建模的自动化效率，又通过二次修复保持了局部突变处几何精度，为类似复杂矿床的工程建模提供了可复用的技术路径与实现方案。
