Add Incremental Timing to an Electronic Initiation Pattern

For context and examples, see Initiation Patterns.

Activity Steps

1. Select the Initiation module.
2. Select an electronic initiation pattern in the DataBlast Items Tree.

   The pattern displays in the Viewport.

3. On the Initiation Pattern Ribbon Menu, in the Electronic Commands group, click Timing Design.
4. On the Electronic Timing Ribbon Menu, in the Timing Objects group, click Add Incremental Timing.

   The X/Y and Z Zone Selection screen displays available zone combinations with the name before the dash being the X/Y timing zone and the name after the dash being the Z timing zone.

5. Select the required zone(s). You can add incremental timing for an individual zone or across multiple zones.
6. Click OK.
7. Update calculation settings:
   1. Select Incremental Timing or a zone in the right-hand panel to limit the scope of the calculation settings.
   2. Update the value for Force Incremental Timing if required for licence conditions or because ground vibration constraints require limiting charge per delay.

      Note: Entering a value other than 0 means that no holes can fire at the same time. The value is the minimum number of milliseconds between holes firing. Always check sequencing and relief after forcing incremental timing. Blast performance may be compromised and excessive delays may promote column dislocation.

   3. If the scope is a zone, enter an Overall Delay Offset if required to delay the firing of the first hole in the zone; for example at perimeters or for mid-splits.
   4. To customise a preset timing value:
      1. Right-click the 1 ms, 10 ms, 100 ms or 500 ms preset value and select Change Timing Value from the menu.

         The New Increment Selection screen displays.

      2. Update the Timing Value.
      3. Click OK.
8. To add timing to individual holes:
   1. Set the Timing Value by entering a value or clicking a preset value.
   2. Click Add Single Increment.
   3. Select the origin hole.
   4. Select the destination hole.
   5. Repeat steps C and D to add timing to additional individual holes.
   6. Right-click or press Esc or Enter to complete the timing.
9. To add timing to a line of holes:
   1. Specify the Search Width.
   2. Set the Timing Value.
   3. Click Add Auto Increment.
   4. Select the first hole in the line.
   5. Select the last hole in the line.
   6. Repeat steps D and E if you have multiple lines to which to add timing.
   7. Right-click or press Esc or Enter to complete the timing.
10. Repeat steps 4–9 to add timing for additional zones if required.

    DataBlast Ignite calculates the delays when all holes in all zones have timing.

    Tips: The Layers Toolbar (Initiation Module) includes options to show or hide the calculated delays. For each additional timing object, ensure that you select the timing object in the right-hand panel to see the holes for the applicable zone.

11. To check if any holes are missing timing, click Show Holes with Timing Constraints.
12. Click Save Changes.
