Surface Blast Design
Bench, quarry and civil blast calculation and layout.
PROFESSIONAL DRILL & BLAST ENGINEERING SOFTWARE
Design, time, analyse and report blasts in one connected browser platform.
Web-Blast brings surface, underground and specialised blast design into a professional online workspace with calculation, visual geometry, charging, physical tie-up, animation, predictions and reporting.
Surface & underground
Independent modules
Connected project data
Professional PDF reports
From design basis to final report
One connected engineering project
Underground Blast Design
Development, ring, longhole and perimeter-control design.
Specialised Techniques
Pre-split, smoothwall and controlled blasting modules.
Timing & Tie-Up
Manual and automatic timing with physical connections.
Charging & Mass
Hole-by-hole charge columns, decks, stemming and MIC.
Animation & Contours
Playback, signal movement and nominal timing fronts.
Analysis & Reporting
Fragmentation, vibration and branded PDF reports.
CONNECTED ENGINEERING WORKSPACE
Use the whole design workflow or open only the module you need.
A user can create a complete project or go directly to timing, charging, fragmentation, vibration, animation, pre-split, smoothwall or reporting without completing compulsory steps first.
Calculate
Use editable geology, explosive and geometry inputs to generate a first-pass design basis for competent-person review.
Design visually
Generate, import and edit holes, rows, rings, free faces, lines, annotations, charging profiles and timing connections.
Analyse and report
Review MIC, fragmentation, vibration and timing results, then generate a branded technical PDF from the same project data.
SURFACE, UNDERGROUND & SPECIALISED
Purpose-built environments for different blasting work.
Surface Blast Design
Calculate and edit production, quarry and civil bench blasts using geology, hole diameter, explosive properties, powder factor and site geometry.
- Burden, spacing, stemming and subdrill
- Square and staggered patterns
- Free-face, crest and toe tools
- Charging, timing, MIC and predictions
Underground Blast Design
Design development rounds, cuts, easers, perimeter holes, lifters, production rings and longhole layouts in a dedicated underground workspace.
- Development and tunnel rounds
- Ring, fan, collar and toe geometry
- Smoothwall and perimeter control
- Pull, drilling and charge summaries
Controlled Techniques
Open dedicated modules for pre-split, smoothwall, timing-only, fragmentation, vibration and other controlled-blasting applications.
- Independent module access
- Editable decoupled charging
- Coordinate import and timing-only use
- Detailed technical reporting
PROFESSIONAL OUTPUT
Engineering information that remains connected from input to report.
Add, move, select, copy, delete and group holes. Draw and edit engineering objects and annotations.
Create and edit directed timing connections with cumulative nominal delays, MIC groups and network validation.
Apply stemming, explosives, decks, primers and charge factors by hole, selection, row or full pattern.
Inspect signal travel, firing states, timing fronts, contours and delay groups using the live timing network.
Review fragmentation and vibration estimates using transparent, editable and site-calibratable parameters.
Generate company-branded reports containing project basis, calculations, tables, design information and disclaimers.

Engineering design aid
Web-Blast cannot directly verify actual geology, water, voids, drilling deviation, explosive condition, installed connections, detonator scatter, nearby receptors, actual site response or legal compliance. All designs and outputs require independent verification and competent-person approval before use.
WEB-BLAST PROFESSIONAL
Move from calculation to a complete visual blast design.
