Grid Reserves menu contents
This section provides a summary of the Grid Reserves submenu and its available options.
Use the In Situ option to calculate approximate reserves for a nominated horizon, usually a coal seam, for selected blocks or polygons. These figures are displayed as a formatted list in the Report Window of Vulcan.
Use the Reserves option to calculate the reserves between two surfaces in one or more polygons. These surfaces are defined by grids or data points, which must be displayed so that they can be selected in the usual manner.
Use the Bench option to calculate the volumes between two surfaces, in one or more polygons, with the volume split by a third surface, typically a bench. The bench surface may lie completely above or below, or may intersect one or both of the limiting surfaces.
Use the Resource Polygons option to create resource polygons based on distances from drillholes or points of observation.
