Abstract


In this paper, the system of measurement and acceptance Junggar coal mine project as research background , proposed taking into account characteristics of the open pit stepped terrain modeling theory and method , and according to the production plan to build a virtual open-pit stope DEM model to study the stope model dynamic update method. To sum up , mainly to complete the following tasks : ( a ) take into account the steps elaborated characteristics stope DEM modeling theory , proposed open pit with constraints stope fine DEM model algorithm ; ( 2 ) under the open pit production plan proposed to build a virtual method DEM model stope stope model and dynamic updating algorithm to solve the old problem of seamless splicing between models ; ( 3 ) research and realized using fine DEM model stope method of calculating the amount of open pit stripping ; ( 4 ) gives the DEM model based on open pit mining field data stope detailed temporal database design , and proposed solutions based on this data at any time stope extraction and display algorithm ; ( 5 ) the use of a continuous stope DEM model and virtual reality technology to achieve the mining process and advance the demo playback , built for the digital foundation pit construction geospatial information framework and platform .
