【摘要】 以地理信息系统技术为核心,建立露天矿采场时空数据库,通过构建采场的时空数据库,动态描述露天矿生产的剥、采、排过程,为露天开采的规划、设计、生产调度管理的优化预控决策提供全方位的空间信息支持。提出考虑台阶特征的不规则三角网(TIN)的露天矿采场三维建模理论与方法,采用基于基态修正和时间快照模型构建露天矿采场时空数据库,通过地理信息系统和虚拟现实技术,实现开采过程的回放和生产计划的超前演示,为数字露天矿建设构建基础的地理空间信息框架与平台。更多还原

【Abstract】 With the technology of Geographic Information System(GIS) as the core and establishing the spatio-temporal database of an open pit stope for the goal,abstracted the change process of 3D geographic-spatial information on a time sequence from the open-pit exploitation production process,through the construction of the stope spatio-temporal database,dynamically described the open-pit exploitation production process,provide comprehensive spatial information support for the optimal pre-control decision-making of an open-pit exploitation,such as planning,design,production scheduling management.Brought forward the TIN theory and method of an open-pit stope considering its step feature,established the stope spatio-temporal database with essential status revision and continual snapshot model,through GIS and Virtual Reality(VR) technology,actualizes the exploitation-process playback and production-plan ahead demonstration,establishes the framework and platform of basic geographic-spatial information for the digital open-pit construction.更多还原
