Owing to the complexity and variability of Southern Africa’s geology, mining operations require innovative, robust technology capable of custom blast patterns. Explosives manufacturer BME’s advanced AXXIS Titanium electronic initiation system (EIS) meets these needs while unlocking improved efficiency, among other benefits, reports technology and marketing GM Nishen Hariparsad.

The AXXIS Titanium system is already deployed across key mining jurisdictions in sub-Saharan Africa, including South Africa, Namibia, Botswana, Zambia and the Democratic Republic of Congo, as well as West African countries.

In South Africa, the AXXIS Titanium system supports large-scale chrome and coal operations, while in Zambia and the DRC it has been effectively applied in copper mining.

The AXXIS Titanium system facilitates the design and execution of “highly complex, precisely timed blast patterns that are unattainable with conventional systems”, he explains.

This enables mines to effectively navigate their operation’s geology, and stringent environmental, social and governance (ESG) requirements while boosting production and lowering costs, he says.

The AXXIS EIS provides 0.0025% firing accuracy, programmable delays of up to 35 seconds at one-millisecond intervals, and the ability to initiate up to 20 000 detonators in a single blast.

“This level of precision and performance provides consistent, high-quality blasts with superior fragmentation, optimal muck-pile shapes and tightly controlled dilution,” says Hariparsad.

He explains that the system demonstrates strong versatility across varying commodities and mining methods, making it suitable for surface and underground applications, without limitation to specific ore bodies. These include openpit coal, iron-ore, copper and diamond operations, as well as underground gold and platinum mining.

Sustainable, Cost-effective Mining
Precision timing has become a “critical enabler” of sustainable, cost-effective mining, emphasises Hariparsad, elaborating that predictable fragmentation, optimal muck-pile shapes and tightly controlled dilution improve downstream processes.

More controlled blasting also reduces instances of vibration, air-blast and fly-rock, reducing environmental impact and disturbance to surrounding communities.

“The system’s ultralow-energy design reduces power consumption during blasting, contributing to a smaller carbon footprint,” he adds, explaining that this supports compliance with local regulations and global ESG standards, both of which he says are key to securing investment and maintaining a social licence to operate.

Openpit operations benefit from the system’s ability to execute larger blasts with fewer tie-ins and less complexity, “making it well suited” to high-volume operating conditions, says Hariparsad.

“Larger blasts improve planning, hauling, muck-piling and crushing efficiencies, enabling more ore to move through the mill with less disruption, resulting in higher productivity, reduced downtime and a lower cost per tonne mined,” he elaborates.

In underground operations, the AXXIS Titanium supports robust safety protocols, which is critical in operations where deep-level conditions, seismicity and complex geotechnics are common.

“Each detonator incorporates a Swiss-designed application-specific integrated circuit chip,” says Hariparsad, explaining that this provides multiple internal safety gates against stray currents and lightning.

Additionally, lower vibration levels from controlled energy release further enhance safety.

In terms of reducing equipment needs and simplifying processes, the AXXIS Titanium streamlines operations through a multi-functional logger that integrates programming, testing, firing and fault-finding into a single device.

The system further integrates with BME’s Blastmap software and cloud platform, enabling efficient blast design, real-time data capture and post-blast analysis.

Reliable Support
As the AXXIS Titanium system is locally designed and manufactured, BME enables reduced reliance on global supply chains, thereby improving the system’s availability and shortening lead times.

“This is particularly valuable in Africa, where logistics can be complex,” he says.

Further, BME’s regional footprint ensures rapid onsite support from experienced technical teams, complemented by continuous product improvement which is driven by close customer engagement.

The AXXIS Titanium reflects BME’s commitment to aligning research and development with operational realities, points out Hariparsad, elaborating that BME collaborates closely with mine operators, contractors, original-equipment manufacturers and regulators to develop solutions for Africa’s unique conditions.

“These partnerships ensure technologies are both technically robust and operationally future-fit,” he elaborates.

To drive continual improvements, BME remains focused on enhancing system durability in harsh environments, expanding digital integration and developing targeted training programmes.
