ICAMPS MineSimU - Geology Features The simulated mining module requires geological and quality data in order to compute the total material mined (raw tonnage), processed tonnage and raw or processed quality for each timing sequence.
ICAMPS accepts gridded seam models from MineSurf or other geological modeling systems. Individual parameter grids are combined into a master grid which contains up to fourteen parameters. A master grid must be assigned to each mining area. ICAMPS has the capability to simulate mining with multiple grids concurrently; one mine plan drawing can reference up to twenty different master grids. This feature is especially useful for multi-seam mining or where the available data justifies one or more fine grids in part of the mine and course grids elsewhere.
MineSimU also has graphical grid editing and compositing functions. Where bore hole data is relatively sparse, coarse grids are typically used. But, where more information is available, such as a longwall panel after development, a segment of the coarse grid can be refined to a small increment and the grid node parameters can be graphically edited to reflect local anomalies.
Where seam characteristics and equipment size require taking out-of-seam material, seam grids can be composited with the immediate roof and/or floor to reflect the actual quality of the shipped product.
Each grid can contain a difficulty code to reflect adverse mining conditions. This information is used to change the miner units productivity. Typical the geologist will outline problem zones on the seam map, and the planning engineer assigns the difficulty codes and productivity adjustment factors. Graphical grid editing is especially useful for creating difficulty code grids because the adverse conditions usually change abruptly and cannot be accurately represented with mathematical seam modeling techniques.
For overburden removal in surface mining, one of the grid parameters must be the overburden thickness. Where the deposit varies significantly in the vertical dimension and is thick enough to be removed in separate homogeneous layers or benches, each layer can have its own master grid.
