Reconcile Data

Once stockpiles have been balanced material movements can be balanced using the reconciliation menu item.

  1. To reconcile material movements, click on the Reconciliation > Survey menu item, to display the below page.

  2. Select the survey Type the material movements will be reconciled for.

  3. Select the Period that material movements will be reconciled for. The start and end dates for the selected period will be displayed to the right of the selected period.

    Note: Periods that have been locked will not appear in the Period lookup.

    In the above example the data for the March 2014 period will be retrieved from where the monthly survey adjustments can be made.

    Note: The Survey Volume will be 0.00 until survey values have been entered.

  4. Once the period and survey type have been set press the Load Data button. MiiNT presents Opening balance, inputs, survey inputs, output, survey outputs and closing balance for each reconciliation group. You can adjust survey movements until each group balances:

    In the above example all of the Reconciliation Groups associated with the Survey Volume reconciliation type have been displayed along with the total actual input and output, and survey input and output movements for the selected period.

    In the above example all of the outputs from the Pit reconciliation groups equal the inputs into the Stockpiles, Dumps, General and ROM.

    Note: MiiNT displays the balance of each group based on the following: Opening + Inputs – Outputs = Closing

    The numbers shown above are the calculated volume, if the Balance has a large difference then the truck factors and densities used to calculate the movements should be reviewed and updated. If a group does not balance the user will need to investigate why the data does not add up and fix it.

    To reconcile the pit you must enter the survey volume, as ex-pit movements will never balance. Survey volumes can be entered at the Pit level or right down to the mine block level.

    Note: MiiNT allows you to adjust the survey input and output values on the reconciliation page. Any adjustment made to the Pit outputs will affect the inputs to the stockpiles, Dumps, General, ROM or Topsoil locations.

  5. Select the Save Data button to save any movement adjustments.

Note: Currently it is only possible to reconcile the Load and Haul volume movements. In the future we would like to be able to support many reconciliation like tonnes in the processing plant, with a rule for each of the different reconciliation.

For a more detailed explanation on balancing reconciliation groups refer to the Working Example topic.

A period is reconciled when the total outputs from all pits equals the total input to the stockpiles, dumps, general, ROM and Topsoil locations, as is demonstrated in the above reconciliation results. When these values are not equal the following checks will need to be performed:

Check the output values for all pits

Run a query for the same reconciliation period (01/03/2014 to 31/03/2014) as detailed in the Pre Reconciliation Process topic. Expand the reconciliation groups in the Reconciliation page to display the Location Groups and check that these Location Groups have been assigned to a Reconciliation Group on the Reconciliation Group Filters configuration page.

In the above example of the Reconciliation page the Reconciliation Groups have been expanded displaying the movements for the Location Groups assigned to them.

In the above example of the Reconciliation Group Filters records, there is a mapping for each Location Group that appears under the Reconciliation Group in the example from the Reconciliation page above.

Check the input values for Stockpiles, Dumps, General and ROM

Expand the Stockpiles, Dumps, General and ROM reconciliation groups in the Reconciliation page to view the individual stockpile inputs, and inputs to the waste dump, the ROM Pad, Crusher and Underpass and the ROMs.

In the above example of the Reconciliation page the STOCKPILES, DUMP, GENERAL and ROM Location Groups have been expanded to display the inputs to the individual stockpiles,waste dumps, ROM pad, Crusher, Underpass and ROMs.
