Backfill
This module is a collection of tools to aid in the design of backfill in stoping operations. Users can simulate filling in their stope geometry from multiple fill locations and with different fill beaching angles. This allows for volume calculations of partially rock-filled stopes. Bund capacities can also be calculated by removing the fill barricades. There is also a tool to simulate the flow of paste along the input reticulation path. This can be used to ensure the gravitational flow will overcome the pipe friction and reach the stope successfully without blocking the line.
Several analytical methods from various sources have been implemented in the app to estimate the stresses within the fill mass and the required UCS for vertical and horizontal exposures. A database of UCS test results can be used to fit a strength prediction model. The model can be used to predict the UCS based on the binder and tailings type, binder %, and age.
