Explosives and blasting: remote systems and design shifts for mine engineers
Reviewed by Joe Ashwell
First reported on International Mining – News
30 Second Briefing
Explosives and blasting suppliers are rolling out remote and automated systems to keep personnel away from the underground face and surface bench during loading and initiation. Technologies include tele-remote blast-hole charging units, wireless electronic detonators with encrypted bidirectional communication, and blast management platforms that sequence shots from control rooms. For geotechnical and mining engineers, this shift changes blast design constraints, demands more precise timing and burden control, and requires closer integration of drilling data, fragmentation modelling, and ground control plans.
Technical Brief
- Remote blasting systems are being engineered to satisfy existing shotfiring rules without rewriting statutory explosives codes.
- Suppliers are integrating misfire diagnostics and automatic lock-out logic to prevent re-energising circuits near suspected duds.
- Blast-control interfaces now log all arming, disarming and firing actions to support incident investigation and regulatory reporting.
- Encrypted firing commands are coupled with device authentication protocols to reduce risk of spoofed or unauthorised detonations.
- Underground deployments are being designed to operate reliably in high-humidity, conductive dust and low-visibility headings.
- Surface bench solutions must maintain safe stand-off distances while coping with variable stemming heights and collar conditions.
- Some systems incorporate built-in self-tests on detonators and controllers before arming, reducing manual continuity checks at the face.
- For similar projects, adoption often triggers updates to mine emergency plans, exclusion-zone design and shotfiring training curricula.
Our Take
International Mining also appears in coverage of Boliden’s “green fleets” roll-out, suggesting its explosives and blasting feature is likely to be read alongside content on decarbonised mobile equipment and may influence how operators think about integrating low-emission blasting into broader fleet strategies.
International Mining’s role as a media participant in events like the World Mining Congress 2026 indicates that insights from this blasting feature are likely to feed into conference discussions on mine productivity and safety standards rather than being purely product marketing material.
