| 中文摘要: |
| 在融合面向实体的数据模型和网格数据模型的基础上,引入参数化对象,设计了一种参数化、网格化的数据模型(PDENDM)用以模拟自然崩落法放矿过程,解决三维可视化环境下考虑时态和经济因素的放矿管理难题,包括放出体发育过程、多漏口放矿及配矿问题.运用面向对象的思想建立PDENDM模型的主要数据结构.PDENDM采用面向实体的元素描述矿岩体及离散颗粒的实体特征,用网格元素描述系统内部网格的空间拓扑关系,并用参数描述实体轮廓、定位信息和其他属性信息,并结合实例分析PDENDM在自然崩落法放矿模拟中的作用.研究结果表明:该模型能够实现自然崩落法放矿过程的空间分析、时态分析,清晰地描述了不同放矿高度下单漏口放矿放出体形态发育及属性的变化,解决了矿岩颗粒流动及放出体发育等放矿研究中的关键问题,为后续多漏口放矿及配矿问题的解决奠定了良好基础. |

| To take oredrawing simulation of block caving,a new networked,hybird and parametric discrete entity-network data model (PDENDM) was designed,which integrates entity-oriented data model and network data model and has some parameter elements.The object-oriented data structures of PDENDM were given.PDENDM describes the features of ore-rock body and discrete particles with entity-oriented elements and the spatial topology of inner network with network elements.It defines the entity outline,position information and other attribute information with parameters.Finally,the model was applied to oredrawing control simulation of block caving in 3D visualization environment.Research results show that the model is suitable for spatial,temporal analysis of oredrawing of block caving.It describes the development of drawout body and attribute changes.It solves the key problems of oredrawing,laying a good foundation for multi-funnel oredrawing and subsequent ore matching work. |
