As bunding is a common control for managing uncontrolled rilling of material at a drawpoint, a bund calculator has been added into the inrush management app. It allows the user to input various measurements for each drawpoint including brow to bullnose distances, brow height, rill angles of the drawpoint material, the amount of overbreak experienced. These then combine with global user defined parameters for bund height, bund rill angle and the amount of space needed for operational reasons to test if the designed bund can fit in the available drawpoint crosscut (in a block caving situation) and determines the location of the bund apex from the brow to manage the volume of material that could rill prior to the brow choking off.

Please see this link for information about the module.

Overview of app for visualising block cave risks.

The data requirements for using this app will vary based on information currently collected by each individual operation. The general data requirements can be broken into three main categories:

Cave maturity

Tools for monitoring drawpoint conditions and inrush events.

Dashboard tools for inrush risk reporting and TARPs.

Framework for monitoring and controlling inrush hazards.
