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.
In order to solve the difficult problem of dynamic construction of three-dimensional model of complex ore body in spatial form, a solution approach is proposed based on determining the essential attributes of its spatial distribution: Attribute-Structure (PS) dynamic modeling, The ore attribute model is constructed within the scope of the ore body and then the attribute model and structural model of the orebody are dynamically extracted according to the constraints of different industrial index parameters etc. In detail the driving mechanism of the traditional orebody modeling method and the dynamic modeling The principle, the characteristic and the realization process of this method are elaborated on the basis of the essential attributes.The theoretical analysis and practice show that the method of dynamic modeling of the ore body PS can dynamically build the complex shape with high quality and efficiency, The abundant three-dimensional model of ore body has certain practicality and theoretical significance.
