Volume Calculations

The paste volume calcs use the mine geometry app to input surveyed geometry. Paste is deposited into the geometry from a specified pouring location. The path of the paste flow is simulated according to the beach angle. The beach angle informs the maximum horizontal spread of the paste. The effect of overburden pressure (pushing paste uphill) or additional flow effects are not considered.

1. Choose surveys to use in paste volume calcs. The geometry should include the stope and any development that may be included in bund capacity. Reload surveys if required.
2. Add barricades. Specify barricades from the centre, height, width and rotation. Ensure barricades completely block off the geometry (excess height and width is ok). Only vertical barricades are accepted. Use the annotations tool to quickly grab coordinates. Specify bunds in the same way, use the bottom of the development as centre and specify the height as double the bund height. Barricades can be named with the edit function
3. Specify the pouring location. Paste will be deposited until either the maximum volume is reached or the pour location is filled. The volume is estimated by treating the boundary cells as a fraction of the full grid cell volume (default 0.5). This is because the blocked geometry usually exceeds the survey geometry.
4. Tick walls or bunds on or off to investigate bund capacities. Use the volume filter to find the volume where the paste overflows the bunds.
5. Specify runs. Edit the runs table to add the volume of each run. There is a marker style for the run number in the 3D view.
