Study on Data Model for Oredrawing Simulation of Block Caving
摘要
Abstract
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.关键词
