摘要
针对空间形态复杂的矿体三维模型动态构建难度大的问题,从决定其空间分布的本质属性出发,提出了一种解决途径:属性-结构(P-S)动态建模方法.先在较大的空间范围内构建出矿石属性模型;再依据不同的工业指标参数等约束条件,动态提取生成矿体属性模型和结构模型.在详细阐述传统矿体建模方法的驱动机制及决定矿体动态建模的本质属性的基础上,对这种方法的原理、特点及实现过程进行了详细阐述.理论分析及实践表明:矿体P-S动态建模方法能够以较高的质量和效率动态构建出形态复杂、信息量丰富的矿体三维模型,具有一定的可实践性和理论意义.
Dynamic ore-body modeling has always been significant but also challenging both in theory and practice. To solve this problem, this paper proposes an alternative method named ore-body Property-Structure （P-S） dynamical modeling. Ore property model in the mining area is firstly built, and then the needed 3D ore-body model is dynamically extracted and constructed according to certain constrained parameters such as mineral industrial indexes. Based on analysis of the driven mechanism in conventional ore-body modeling method and the essential feature of an ore-body in 3D modeling, the principles, characters and operational process of P-S method are discussed in detail. Either the theoretical analysis or practical application proves that the proposed PS ore-body modeling method is feasible and efficient in high quality ore-body modeling. What＇s more, it improves the 3D geological modeling theory to some extent.
