Pattern Library

The PATTERN LIBRARY tab manages drill and blast pattern definitions. Patterns define the geometric and explosive parameters for different hole types. They can be created manually, imported from CSV, or exported for sharing across teams.

Pattern Card Grid

Patterns are displayed as a grid of cards. Each card shows:

Property	Description
Pattern ID	Unique identifier (e.g., “PROD-229-12”, “BUFF-165-12”)
Type	Hole type badge (PRODUCTION, BUFFER, BATTER, ORE, WASTE, PRESPLIT, etc.)
Bench Height	Design bench height in metres
Diameter	Hole diameter in mm
Burden	Burden distance in metres
Spacing	Spacing distance in metres
Powder Factor	Explosive consumption in kg/bcm
Sub-drill	Sub-drill depth in metres
Stemming	Stemming height in metres
Hole Angle	Angle from horizontal in degrees (90 = vertical)

Card Actions

Each card has three action buttons:

Edit – Open the pattern editor dialog
Copy – Duplicate the pattern with a “-COPY” suffix on the ID
Gantt – Toggle visibility in the Gantt sidebar palette (hidden patterns are dimmed)

Drag and Drop

Pattern cards are draggable. Drag a card onto a blast row in the Blast Overview tab to assign that pattern to a blast.

Add / Edit / Copy Dialog

The pattern dialog provides fields for all pattern properties:

Pattern ID – Must be unique across the library
Type – Dropdown with standard types, plus a CUSTOM option for a custom type name
Bench Height (m), Diameter (mm), Burden (m), Spacing (m)
Powder Factor (kg/bcm), Sub-drill (m), Stemming (m)
Hole Angle (degrees from horizontal, default 90 = vertical)

CSV Import / Export

Export Template

Click Export Template to download a blank CSV with example rows and comments explaining each column. Lines starting with # are ignored on import.

Export Pattern Library

Click Export Library to download the current patterns as a CSV file.

Import Patterns

Click Import CSV to load patterns from a CSV file. The importer:

Skips blank lines and comment lines (starting with #)
Detects the header row by looking for “Pattern ID”
Validates each row for required fields and numeric values
Replaces the current pattern library with the imported patterns
Shows a success/warning message with import counts

Note: Importing replaces all existing patterns. Export your current library first if you want to keep it.

Hole Types

The following standard types are supported, each with a distinct colour:

Type	Description
PRODUCTION	Standard production blast holes
BUFFER	Buffer row holes (typically smaller diameter)
BATTER	Batter (wall control) holes
STAB	Stabilisation holes
FACE	Face holes
CONTOUR	Contour holes
TOE	Toe holes
RAMP	Ramp holes
SUMP	Sump holes
ORE	Ore zone holes
WASTE	Waste zone holes
PRESPLIT	Pre-split holes (line drill)
CUSTOM	Any custom type name

Gantt Palette Integration

Patterns marked as visible appear in the Gantt sidebar palette. From the palette, they can be dragged onto blast rows to assign patterns without switching tabs.

Blast Overview – Drag patterns onto blasts for assignment
Gantt Chart – Patterns appear in the sidebar palette
Import & Export – CSV template exports
