Establishment and application of the virtual stope/ dumping sites model of the strip mine

By using the Geographic Information System (GIS) technology, it is proposed to construct a virtual stope model method, which can reflect mine engineering development status and satisfy geometry restraint relationship, for the technical works, such as the exploitation design, the establishment of production plans and production management in strip mines. With the utilization of the based time series virtual stope/ dumping sites models of strip mines, establishing the spatiotemporal database model of stopes and dynamically describing the process of the strip mine production planning including shelling excavating and casting, it can provide a full range of spatial information support for the optimal pre-control and decision-making of the plan, the design and the production scheduling management of strip mines. Taking the establishment and application of the virtual stope/ dumping sites models of one strip mine for an example, the paper presents the method that establishes the virtual stope/ dumping sites models of strip mines. By using the spatio-temporal data model of the virtual stope/ dumping sites models of strip mines, and GIS and Virtual Reality (VR) technology, it achieves 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 and provides decision-making for mining.
