摘要: 基于Egenhofer的n-交集模型,结合矿山地质的特点,提出了三维地质体Mn×n(4×4,3×3)空间关系模型,极大增强了地质体间空间关系描述能力,解决了包容、镶嵌等空间关系的描述。针对地质体的不确定性,提出了模糊地质体间 Rn×n(4×4,3×3,2×2) 关系模型,可以对附带模糊性的地质体进行详尽的空间关系描述,为矿区地质体拓扑关系查询、分析推理等建立了模型基础。

Abstract: Based on Egenhofer's  n-intersection mode and in consideration of the particularity of mine geology, a 3D model for the Mn×n(4×4,3×3) spatial relation between geological bodies is proposed, greatly enhancing the ability to describe the spatial relation between geological bodies and providing a solution for describing the spatial relations such as inclusion and embedding.In view of the uncertainty of geological bodies, a Rn×n (4×4,3×3,2×2) relation model for fuzzy geological bodies is proposed, which can give a detailed description of the geological bodies with fuzziness, thus providing a model base for the query, analysis and reasoning of the topological relation between the geological bodies in mining area.
