Explosive Forecast

The EXPLOSIVE FORECAST tab projects weekly explosive consumption across the schedule. It helps mine planners coordinate emulsion supply logistics and identify peak loading weeks.

Stats Cards

Four stats cards display above the forecast table:

Card Colour Description
Total Explosive Required Red Sum of all blast explosive mass in kg (also shown in tonnes)
Loading Days Required Amber Total loading days at the configured load rate
Avg PF Cyan Average powder factor across all blasts (kg/bcm)
Charge Source Green Whether explosive data comes from Kirra charge configs or the schedule

The Charge Source card shows “Kirra Config” with the number of loaded configs when charge configurations have been imported from a Kirra project or KAP file, otherwise “Designed” (from schedule data).


Forecast Table

The table breaks the schedule into weekly buckets based on loading start dates:

Column Description
Week Week number and year (e.g., “Wk 8, 2026”)
Blasts Comma-separated list of blast names loading that week
Explosive (kg) Total explosive mass for blasts in that week
Volume (bcm) Total volume for blasts in that week
Load Days Sum of loading days for that week’s blasts
Daily Rate (kg) Average daily explosive consumption for that week

Weeks are sorted chronologically. Only blasts with a load start or blast date are included.


Loading Rate

The loading rate used for forecast calculations is configurable via the input field at the top of the tab. The default is 100,000 kg/day. This rate is used for the forecast table calculations. For actual per-blast loading, the dependency engine uses the combined rate of assigned MPUs.
