Overview

Blasting is the first step in comminution and the cheapest place to break rock, which is why poor fragmentation costs twice, once in loading and again in the mill. This week covers explosive behaviour, blast design geometry, initiation and timing, and the measurement that tells you whether a design worked. Safety and ground vibration run through it rather than sitting in a separate session, because that is how they arise in practice.

It runs 7 times over the published calendar, in 6 cities and live online. Every date is the same programme with the same content and the same certificate.

What you will be able to do

  • Explain explosive energy, velocity of detonation, and how rock breaks.
  • Design a blast pattern from rock mass and fragmentation targets.
  • Select initiation and timing to control fragmentation and movement.
  • Predict and control vibration, airblast and flyrock.
  • Measure fragmentation and feed it back into the next design.

Who should attend

Drill and blast engineers, mining engineers and supervisors, shotfirers and blasting technicians, and quarry managers.

Is the level right for you?

This is an intermediate level programme. It assumes you are working in or moving into the area it covers, and it is built around your own material rather than a case study. If you are unsure, ask an advisor before registering rather than after.

Ask an advisor

How it is taught

Short input, then work. Across 5 days of roughly 6 teaching hours each, the balance sits deliberately with the second: a programme where the trainer talks for six hours produces notes rather than capability.

  • Your own material

    Exercises run on situations delegates bring, not on a case study written for a different organisation in a different decade.

  • A capped cohort

    Small enough that everybody is asked something. Executive programmes are capped tighter still.

  • Practice under scrutiny

    The difficult conversation, the challenged assumption, the decision defended out loud. Judgement is not built by watching.

  • Something to take back

    Each day ends with a thing you can use on Monday rather than a slide deck you will not reopen.

The programme, day by day

Day 1Explosives

Explosives

  • Detonation, energy partition and gas pressure
  • ANFO, emulsions and blends
  • Sensitivity, water resistance and storage
Day 2Rock and breakage

Rock and breakage

  • Rock mass properties that govern a blast
  • Structure, jointing, and how it steers a crack
  • Burden, spacing and stemming
Day 3Design

Design

  • Bench geometry and hole diameter
  • Powder factor and energy distribution
  • Decking, presplitting and wall control
Day 4Initiation and timing

Initiation and timing

  • Detonators, delay and sequencing
  • Electronic against pyrotechnic initiation
  • Timing for fragmentation, muckpile shape and vibration
Day 5Results and control

Results and control

  • Fragmentation assessment
  • Vibration monitoring and compliance limits
  • Flyrock, misfires and post blast inspection

What you leave with

  • A blast design for a real bench or face.
  • A vibration and airblast control plan for a sensitive boundary.
  • A fragmentation measurement routine.

The certificate

A GATI certificate recording what you attended, issued after the programme has run and attendance has been taken. Attending at least 80 per cent of the days earns a certificate of completion; attending less earns a certificate of attendance stating exactly what was attended.

Every certificate carries a code that anybody can check against GATI's own record, which is what makes it worth holding. It records participation. This site will not imply one it does not have.

Questions

Who is Blasting Knowledge for?
Drill and blast engineers, mining engineers and supervisors, shotfirers and blasting technicians, and quarry managers. It runs at intermediate level within Mining Engineering, so it assumes you are working in or moving into that area rather than meeting it for the first time. If you are unsure whether the level fits, ask an advisor before registering rather than after.
How long is it, and what does a day look like?
5 days, running to roughly 6 teaching hours a day. Sessions are built around your own material rather than a case study, so a day alternates between short input and working on something you brought. The full outline is on this page, day by day.
What does it cost, and what is included?
The next published date is Live online at US$995 per delegate. The fee covers tuition, all programme materials and the certificate. Travel, accommodation and visas are arranged by the delegate. Fees vary by city, and every published date shows its own.
Can it be delivered for my organisation only?
Yes. Any published programme can run as a private cohort, on dates that suit you, in your city or online, built around your own material. That is a different conversation from registering an individual, and it starts with what capability you are trying to build rather than with a course title.
What certificate do I get?
A GATI certificate recording what you attended, issued after the programme has run and attendance has been taken. Attending at least 80 per cent of the days earns a certificate of completion; attending less earns a certificate of attendance stating exactly what was attended. Every certificate carries a code that anybody can check against GATI's own record.
Is the online version the same programme?
Yes. The same faculty, the same material, the same cohort cap and the same certificate. It is not a recording and it is not a reduced version. It exists because travel budgets and visa timelines rule people out of a room they should be in. The classroom version runs in Kampala, Cairo, Dubai, Nairobi.

Want to take this further?

Register on a published date, or tell an advisor what you need and they will come back with something specific rather than a brochure.
