Image Added

Description of each option see below:

Table of Contents

Select a level from the dropdown where to generate automatic blast shapes: Selected/Current/Visible Blasts/Benches/Flitches and Digs.

Image Added

Remove Existing Designs

Flag this option to clear existing linework from the specified level.

  • If flagged, no need to use the Delete Designs tool.

  • If not flagged, new shapes will be applied over existing ones.

Generate Ramp Shots

Image Added

Flag this option to automatically create a closed polygon around a section of ramp that is less than a user-defined depth.

  • Enter the Ramp Shot Minimum and Maximum Angles (in degrees).

  • By default, ramp shots are displayed in blue.

Generate Trim Shots

Image Added

Flag this option to automatically create closed polygons around a section of Bench/Flitch against the wall.

  • Note that for Trim Shots to be generated, the wall area must be defined in the Wall Control Designs step.

  • Set Trim Shot Length and Width (in meters).

  • By default, ramp shots are displayed in green.

Generate Internal Shots

Image Added

Flag this option to automatically create closed polygons around of Internal (Production) Shots.

Image Added

Refer to the table below for a description of the settings for generating internal blasts.

Fitted Blasts

Generating blasts following the Bench/Flitch contour.

Image Added

Straight Grid

Straight gris across the Bench/Flitch.

Image Added

Size X and Size Y

Set the Size X and Size Y to the blast dimensions.

Note that for medium or long-term planning (ATS), size of the blocks should be relatively large, while for shorter planning horizons (APS) they can be smaller in order to provide more details when sequencing mining.

Note

The smaller the size of the blocks, the longer it takes to generate and process them. Keep this in mind when working with larger mines models.

Bearing

Set the Bearing to match the pit orientation (for example, 120°).

Image Added

Bench Offset X and Y

Create from Corner/Center

Create Shots grid from a defined corner/center.

  • Click to start drawing the grid.

  • Choose a bearing and first axis size.

  • Choose a Y axis size.

  • Left-click to confirm. The Generate Blasts window will reopen. Edit, or click OK to confirm.

Image Added

Cell Merge Proportion

Specify proportion to merge adjacent blocks, ie, if some are too small.

Image Added

Generate Contour Shots

Image Added

Flag this option to automatically create closed polygons around of shallow Contour Shots.

  • Specify the Minimum Contour Area (in meters).

  • By default, ramp shots are displayed in purple.
