A training course for JKSimBlast is usually focussed on one or more of the design modules. Typically, there are two parts:

  1. Basic blast design starts with an introduction to the program, and covers the necessary design tools to create or import blast holes, load decks and delays, and run a detonation simulation. This is followed by the simple analyses to ensure compliance of the blast with basic KPIs, such as detonation sequence, powder factor, maximum instantaneous charge, and cost.
  2. Blast analysis covers the calculation and interpretation of the major analyses, such as timing scatter, relief rate, burden relief, vibration, energy distribution, damage contours, and fragmentation.

For a small group of experienced blasters, these two parts usually require one day each. A further day is required to cover advanced design tools, such as electronic delays, and other software modules, such as version 3. A basic introduction to JKBMS can usually be integrated with training for one of the design modules, requiring only a small amount of extra time.

In general, three days is sufficient to cover all the basics and some advanced applications for an experienced group of up to 5 people. A large group may require a minimum of four days.

A typical course agenda may consist of:

Day 1 – Basic Design
  • Basics: design modes, parameters, scale, anchor, goto, preferences
  • Design: create a blast: strings, holes, decks, downhole and surface delays, detonation simulation
  • Data: save a blast, comments, display, BMS introduction
  • Edit: selecting data, cut/copy/paste, query, modify, import
  • Analysis: totals summary, powder factor, timing contour
Day 2 – Analysis
  • Timing Analyses: relief rate, max. inst. charge & vibration, burden relief
  • Charge Analyses: energy, damage, fragmentation
  • Output: printing, tables, sharing data
Day 3 – Advanced Tools
  • BMS: objects, data management, 2D / 3D views
  • Electronic Delays: design tools
  • Hole Layouts: polygon fill, baseline, follow line
  • Hole Tools: trim to surface / plane / boundary, templates
  • JKSimBlast v3: display, analysis types, 3D reports, linked data

The training schedule can be varied to accommodate any specific interests, particularly to incorporate current blast designs, but also to develop a design procedure and customise the software during the course to fit in with or adapt to your current design and implementation process.

Training rates are charged on a daily basis, but vary depending on the number of trainees and whether any extra time is required. Travel, accommodation and other expenses are charged at cost. Contact Soft–Blast for details.
