RR. Project Setup Example

The purpose of Rapid Reserver (RR) is to prepare geological reserves for scheduling in the Alastri scheduler.

This section provides step-by-step instructions for creating such a project, including instructions for setting parameters, creating solids based on the current survey, working with blasts and mining blocks, reporting and plotting the data of interest, as well as exporting the prepared reserve model file for further use in mine planning.

To get a valid project file (based on the demo data), go through the following steps in the given order.

Project Setup

Creating and opening a project

1. Download the latest version in the Alastri Hub portal and start Rapid Reserver.

2. Create a new project and name it "RR. Quick Start Demo Project". The main Rapid Reserver project file is saved in ".rara" format.

Open

Run the latest version of Rapid Reserver and create/open ".rara" file

1. Settings step

• Select the units of measurement. In the Quick Set field, select the metric units (Metric).

• Depending on which options are ticked in the Options section, different steps appear in the Setup Tasks list. In the current project, In this project, we will need the Block Model, the Block Model Gap Filling, and the Dig Plans features.

• Set the thresholds for error (Error Finders) and remnant blocks exclusion (Discard Thresholds). Set the minimum block area to 50 bcm.

• In the Hatch Patterns area, select a pattern from the dropdown list to highlight different areas for phase exclusion, blasts, or grade control.

Open

• Press the blue plus icon to run this step and proceed to the next one.

2. Tables step

• Long term projects may schedule to the Bench/Blast level.

• For Shorter term projects sites can schedule to Flitch and Dig blocks.

• The more blocks are created in Rapid Reserver, the slower the final schedule is, so only create down to the level required.

1. Add Flitch and Dig Levels to the Reserves table.

2. Verify that the levels in the Association column are assigned correctly.

3. Check the Auto Unique column to automatically assign blocks with unique names.

4. Select the relevant images for each level.

5. Press the blue plus icon to run this step and proceed to the next one.

3. Block Model step

1. Click the New button to open the Reservable Models Generator window.

2. In the Import CSV file window, select the applicable parameters and set the Header Line and Data Offset, if necessary.

   1. Set the green Header Line to match the header text.

   2. Set the yellow Data Offset to match the first row of data.

   3. Press OK to finish.

Once the block model has loaded, its header fields are listed in the Variables panel on the right.

The Field column (on the left) lists the fields of the reserves model, and you will need to map them with the fields from the imported block models.

If required variable is not available, you must create/edit it in the Script Editor window, which can be accessed via the Custom Variables button.

When the field mapping is complete and there are no errors, click Generate to create the reserves model. Specify the saving path and file name. The new model will be saved in ".resmodel" format.

• Review values in the Reserves Summary panel. Use the visibility toggle to display the actual, minimum and maximum values for the mapped fields.

• Press the blue plus icon to run this step and proceed to the next one.

4. Block Model Gap Filling step

Option to fill voids in block models with a default material. Where the mining solid surface is outside the block model extents. Gap filling material should be waste, if it could be anything else, discuss with the geologists who prepared the blockmodel. If gaps are present and gap fill is not used, the schedule will apply zero tonnes for this mining area.

1. In the Gap Filling Presets column, add a new preset for the material used to fill the voids. Name it, for example, "waste".

2. In the Parcel field select "w" (waste) from the dropdown.

3. Set DryTonnes to 2.75 and wetTonnes to 2.895.

5. Phases step

Import phases and layers.

You can import from a file, Solid Lab tab, or a third-party package (Vulcan/Minesight/Surpac).

Use the vertical slider (between the phases list and the view area) to check for overlaps.

• Overlaps are a problem when material is included in multiple phases leading to double counting of tonnes – this must be fixed. So each block is mined only once.

• Here we see that the same area is used for 2 different purposes: first Pit is mined out, then the area is used as a backfill. The block is mined once, the area is then available to backfill with waste.

6. Blast Properties step

If extra properties (that are not mapped across in the Reserves Model) are required for later scheduling purposes they can be added here under the relevant step (Phase Properties, Blast Properties, Dig Properties ).

1. Create a new property for Density (Default 2.75).

2. Add a PctDrilled property - for a schedule that has drilling. Default is set to 0, in the Designer tab can set blocks as already drilled or partially drilled (have to script in drilling in the Scheduler).

   1. If you select the Choice property type, create comma-separated properties (0,1) that can be selected from the Default Value dropdown.

   2. If you select the Number property type, enter a numeric Default Value.

7. Bench Templates step

Click the blue plus sign icon in the Bench Template panel to add a new template.

1. Add a New Template for pit bench = Pit_10m

   1. In the Bench Naming field tick Bottom.

   2. Set bench template height to 10.

   3. Ensure that the template fits the pit design (Pit1_s1). The red template should match the pit solid contours, without offsetting.

2. Add a new template for dump lift = Dump_20m.

   1. In the Bench Naming field tick Top.

   2. Set bench (lift) template height to 20.

   3. Ensure that the template fits the dump design. The red template should match the dump solid contours, without offsetting. For Dump1 a template set to 20m lifts will be offset against the design, as shown below.

To fix, set the RL for the template used for Dumps 1 and 2.

1. Add a new template for dump offset = Dump_Offset_20m.

2. Select “Add to Bottom”.

3. Add Reference Level = 10.

4. Set Height 20m above and below the reference (Rl).

Check Dump1 and 2 using the new template - the red template should fit the lift design.

Rename Dump_20m to Dump3_20m.

8. Depletion Surfaces step

Update Phases with the latest mine survey.

• Only import blocks relevant to the current schedule.

• Cap Rls can be set – data above/below these levels will not be included in the inventory.

1. Add a depleted surface survey.

2. Select the phases to apply this survey to. Use the <CTRL> and <SHIFT> keys to select multiple.

3. Use the dropdowns to select Upper and Lower depletion surfaces to be applied to the selected phases.

4. In the Layers panel, display the End of Month surface and check the result in the viewport.

5. Press the blue plus icon to run this step and proceed to the next one.

9. Phase Exclusion Areas step

When the Depletion Surface has been applied to the pit phases, in Phase Exclusion Areas step we can remove remnant material from the reserves.

1. Select Z to view the pit in Plan view.

2. Set the vertical slider to identify the areas to remove - remnants on the wall < 1m thick.

3. Draw a polygon around the areas to keep for scheduling.

   1. If mistakes are made in digitizing, use the edit icons to move points etc.

10. Phase Details step

Update phase details for all phases including:

1. Table Type (Reserves or Dumps).

2. Increment Templates (ensure that the correct template is applied).

3. Block Model for pits (for dumps = (none)).

4. Block Model Fill material (waste).

5. Design Position.

6. Silhouette Type.

7. Expand Distance. This value should almost always be left at the default 50 meters.

8. Bench Tolerance.

Make sure that each level is assigned with a unique name. Otherwise, you won’t be allowed to proceed to the next step.

11. Bench Depletion step

Remove or Send Down bench/flitch material of a thickness below specified.

1. Double click a bench to select it.

   1. Use the vertical slider to visually display areas to be excluded (thickness <1.5).

   2. Digitize a polygon around an area to remove/send down – press <Esc> when finished.

   3. Click the drawn block - it will be shown in yellow.

   4. Right-click to display a list of options, available for the selected material. The selected material can be removed or sent down to be mined with the material of the bench below.

2. You can tick a box to remove an entire bench/flitch (if the remnant material percentage is too high).

12. Wall Controls step

Set the measures to protect the pit walls from the seismic loading of major blasts.

Click the blue plus icon to create new wall controls applicable to your project, for example, contour presplit blasting.

Wall is set by default.

13. Wall Control Designs step

Extra properties to define activities that only occur in a wall shot.

Here area defined as Wall will have Trim blasts, with the rest of the bench having Production blasts. With further scheduling, rules can be set so that the production blasts in front of a Trim blast must be mined first.

Areas where Pit1_s1 is adjacent to Pit1_s2 will not require Trim blasting. So this wall should be removed.

1. Select bench required from the Benches tree, it will be displayed in the main viewport.

2. Check the Wall Control for Painting.

3. Press the Remove Wall Icon.

4. Un-paint the area where wall control is not required (adjacent phases).

   1. Use the horizontal slider to adjust the size of the paint brush.

Import and Export

If blasts designs have been created outside Rapid Reserver, they can be imported into the project.

Or Blasts created by Rapid Reserver can be exported and used in another software for drill and blast design.

Import

Import Blast Polygons, as follows:

1. Designer tab > Benches/Lifts panel > Import button > Into Project > Named Blast Polygons.

2. Review the mapping template to choose which files to be imported into which benches/flitches, and how the blasts/digs will be named.

   1. The Blasts are automatically inserted into the correct location.

   2. If blasts are not mapped, they can be dragged into the correct location.

If the previous form is filled out correctly, the next form should be able to identify the correct file to map to each bench due to activating the Map to Files option. If the files are not mapped to the correct bench, you can delete the auto mapping and drag and drop the correct file to the correct bench.

Export

Export reserves model to Alastri Inventory Model files (“.invmodel”) for further import into Haul Infinity or Tactical Scheduler.

More details on different import and export options see here.
