Research of establishment and application for spatio-temporal data models of an open-pit stope

With the technology of Geographic Information System (GIS) as the core and for the goal of establishing the spatio-temporal database of an open pit stope, the process of the strip mine production planning including shelling excavating and casting can be considered as the changed process of 3D geographic-spatial information based on time series, by establishing the spatio-temporal database of stopes, dynamically describing the process of the strip mine production planning including shelling excavating and casting, it can provide a full range of spatial information supports for the optimal pre-control and decision-making of the plan, the design and the production scheduling management of strip mines. It proposed the 3D modelling theory and the method of an open-pit stope of the TIN which is considering its step feature, the stope spatio-temporal database can be established with essential status revision and continual snapshot model, by using GIS and Virtual Reality (VR) technology, it achieves the exploitation-process playback and production-plan ahead demonstration, and establishes the framework and platform of basic geographic-spatial information for the digital open-pit construction.
