ShotLab is a blast design workbench for training shotfirers. Lay out a pattern, charge it, tie it in and fire it, then see the timing, vibration, airblast, flyrock, fragmentation and muckpile. Every check explains what went wrong and where its limit comes from.
Bluestone Quarry from the app, tied in with surface connectors. Grey ties carry the signal; each hole fires 400 ms after its signal arrives.
The same order a shotfirer works in on the bench, with feedback at every step.
Set burden, spacing and depth, or place holes one at a time around voids and services.
Pick the product, stemming and decks. Charge per hole and powder factor update as you go.
Click a start hole and an end hole, or drag along a row. ShotLab checks the sequence and the connectors.
Play the shot slowly and watch the timing, vibration and rock movement build up.
Get a grade, the checks that failed and why, then change one thing and fire again.
A limit in AS 2187.2 is not the same as a rule of thumb. ShotLab labels each check by its source, and shows the working, the source and where each model stops being reliable.

For training only. The predictions are simplified models. Don't use them to design, approve or fire a real blast.
