Construction And Application Of The Open-pit Virtual Stope Model

This thesis proposes level features open-pit terrain modeling theory and method based on the data of Zhungeer, and builds a virtual model of DEM to study the model of dynamic update methods based on open-pit mine production plans. To sum up, we complete the following tasks:Introducing the detail steps features of the theory of DEM modeling method, and putting forward with a constrained open pit mining field fine DEM model algorithm; According to the proposed open-pit mine production plan to build a virtual model of DEM method and dynamic model update algorithm to solve the seamless connection between the old and new model of the problem;Studying and implement how to use the model of DEM method of calculating the amount of open-pit mine stripping and mining;Giving the model of DEM based on open pit mining field of data mining field spatio-temporal database design in detail and put forward the program at any time based on this mining field data extraction and display algorithms;Using a continuous model of DEM and virtual reality technology to achieve extraction process, playback and advanced presentations. To establish framework and platform of geospatial information, we build digital open-pit mine.
