RR. Bench Templates

In the Bench Templates step we create the bench height options that can be applied to phases. You may choose a single template to cover all pits, or have multiple templates for different mine areas.

• 1 Creating one height template
• 2 Creating a mixed-height template
• 3 Creating benches with flitches template

• The templates defined in this step will be used to slice individual pits and dumps to the heights specified (applies in the Phase Details step > Options > Bench Template).

• To ensure proper distribution of pit benches and dump lifts, make sure that the template is applied evenly along the phase solid.

• If the bench is mined by different layers, divide the bench height of the by certain flitches, separated by commas.

• You can set different bench heights above and below a certain Relative Level (RL).

• If the heights of one bench vary in different parts of the pit, then it makes sense to divide the pit into stages according to the mining heights.

• The default bench template is 10 meter increments aligned to the zero^th RL.

Open

Creating one height template

1. Press the blue plus icon to add a new bench template.

2. Rename the bench template to “20m”.

3. In the Definition panel, change the height value to 20.

4. Select a Bench Naming:

   1. If the template is to be applied to the dumps > select Top in the Bench Naming field;

   2. If the template is to be applied to the pits > select Bottom in the Bench Naming field.

5. Select one of the pits/dumps from the Phases list.

6. Click on different heights in the Result panel and inspect how the template is applied in the 3D viewport.

   1. Rotate the phase solid using toolbar or mouse control to see the template applied from different angles.

Creating a mixed-height template

1. Press the blue plus icon to add a new bench template.

2. Rename the template to “Mixed Height”.

3. In the Definition panel, press Add to Bottom button.

4. Change the threshold RL to the elevation where the bench heights change (770m).

5. Set the bench height above the threshold (10m).

6. Set the bench height below the threshold (5m).

7. Review how this template fits pit3 solid in the viewport.

Open

5m benches below the 770RL, 10m benches above the 770RL

Creating benches with flitches template

1. Press the blue plus icon to add a new bench template.

2. In the Definition panel, press Add to Bottom and change the height to 12 m.

3. In the Flitches column enter the comma separated flitch heights (4,4,4).

4. In the Phases panel select pit1_s2 and review in the viewport how this template fits pit1_s2 solid at the 876RL.

Once you are satisfied, press the blue play button to proceed to the next step.
