Blast Overview

The BLAST OVERVIEW tab provides a summary table and calendar view of all scheduled blasts. It supports drag-and-drop pattern assignment from the Pattern Library and displays depth profile visualisations for blasts with imported 3D solid data.

Sub-Tabs

The Blast Overview tab has two sub-tabs:

Sub-Tab Description
Table Data table with all blasts, patterns, metrics, and depth profiles
Calendar Month-grid calendar view showing blast dates

Stats Cards

Four stats cards display above the table:

Card Colour Description
Active Blasts Blue Number of blasts with status “active”
Total Volume Amber Sum of all blast volumes in bcm
Total Explosive Red Sum of all blast explosive mass in kg
Total Holes Purple Sum of all holes across all blast hole types

Blast Table

The table displays one row per blast with these columns:

Column Description
Blast Name Name with dependency warning icon if applicable
Status Badge: active (blue), fired (red), planned (teal)
Mode “Auto” (from Kirra import) or “Manual”
Pattern Pattern code reference
Patterns Hole type badges (PRODUCTION, BUFFER, PRESPLIT)
Volume (bcm) Blast volume
Exp. (kg) Explosive mass
PF (kg/bcm) Calculated powder factor
Drill (m) Total drill meters
Depth Profile Mini bar chart from 3D solid depth binning
Drill Start Scheduled drill start date
Load Start Loading start date
Blast Date Blast fire date
Deps Dependency summary (e.g., “0%->L 100%D->B”)

Pattern Assignment via Drag and Drop

Patterns from the Pattern Library can be dragged onto blast rows. When dropped, an allocation dialog appears with:

Field Description
% Block Percentage of the blast this pattern covers (first pattern defaults to 100%)
Number of Holes Calculated from % Block and surface area, or entered manually
Hole Depth (m) When Use Block Depth is off: benchHt / sin(angle) + subdrill. When on: (Volume / Area) / sin(angle) + subdrill
Drill Meters Calculated: holes x depth (read-only)
Explosive Mass (kg) Calculated from PF x burden x spacing x effective bench height x holes (read-only). Effective bench height = Volume / Area when Use Block Depth is on, otherwise the pattern bench height
Line Drill Yes/No (defaults to Yes for PRESPLIT and BUFFER types)
Hole Type From the pattern definition (read-only)

Live Recalculation

Multi-Pattern Assignment

A blast can have multiple patterns assigned (e.g., PRODUCTION + BUFFER + PRESPLIT). Each pattern gets a percentage of the block. Subsequent patterns default to 0% Block for manual adjustment.


Depth Profile

When 3D blast solids have been imported (via .kap or .kirra files), the depth profile column shows a compact horizontal bar chart. This visualisation comes from vertical ray-casting through the blast solid geometry, showing the distribution of hole depths across the blast footprint.


Blast Calendar

The Calendar sub-tab shows a month-grid view with blast dates plotted on their respective days.

Use the < > arrow buttons to step between months, or click Today to jump to the current month. The month and year are displayed in the calendar header.

Layer Toggles

Toggle visibility of different scheduling phases on the calendar:

Layer Colour Description
Prep Teal Pattern preparation dates
Drill Blue Drilling dates
Load Amber Loading dates
Blast Red Blast fire dates

Each layer appears as a coloured bar on the calendar cells where that phase is scheduled.

Calendar Export

Click the Export button on the calendar view to open the calendar export dialog. Two event modes and two file formats are available:
