LKAB and Epiroc’s Underground Safety System Deployment in 2026

The Invisible Problem at the Heart of Deep Mining Safety

Underground mining has always required workers to operate in environments where the most fundamental navigation tool available to the modern world simply does not function. GPS, the technology underpinning everything from smartphone directions to emergency dispatch systems, cannot penetrate hundreds of metres of rock. For decades, this reality shaped the ceiling of what underground safety systems could realistically achieve.

Zone-based personnel tracking, dividing mine workings into broad geographic segments and estimating worker locations accordingly, represented the practical frontier of what legacy communication and tagging infrastructure could support. In smaller or shallower mines, that approximation carried acceptable risk. In deep iron ore operations pushing beyond 1,000 metres, and increasingly beyond 1,500 metres, the information gaps created by zone-level approximation during emergencies represent a materially different category of hazard.

That structural limitation is now being directly challenged. LKAB partners with Epiroc on an underground safety system that moves the operational baseline from approximate zone-level location awareness to precise, real-time 3D positioning, and the implications extend well beyond the two Swedish mine sites where the technology is being rolled out.

Why Zone-Based Tracking Became Insufficient

The mechanics of traditional underground personnel tracking are straightforward. Physical tags assigned to workers interact with fixed readers positioned at key infrastructure points, feeding location data to surface control rooms as personnel move through designated zones. The system answers a basic question: which zone is a worker in right now?

For emergency response, however, that answer is rarely sufficient. A zone spanning hundreds of metres of tunnel network provides limited actionable intelligence when rescue teams need to prioritise deployment, when control room operators need to confirm evacuation completion, or when workers themselves need to navigate toward a rescue chamber through unfamiliar corridors after a seismic event or ventilation failure.

The deeper a mine operates, the more these limitations compound. Furthermore, the convergence of automation in mining and increasing operational depth means the consequences of inadequate tracking are amplifying across the industry:

• Complex ventilation architectures create multiple pathway options that zone-level data cannot distinguish between
• High-traffic mixed human-machine environments increase collision risk during emergency evacuations
• Extended depth means longer evacuation routes and higher reliance on accurate navigation
• Seismic activity, more prevalent in deep iron ore formations, can alter tunnel accessibility without warning

Legacy zone-based systems were not designed to fail workers. They were designed around the technical constraints of their era. The emergence of robust underground Wi-Fi infrastructure, mobile computing, and 3D spatial mapping software has fundamentally changed what is achievable, making the gap between what was acceptable and what is now possible larger than at any prior point in the industry's history.

What the Epiroc System Actually Delivers

The platform deployed across LKAB's operations is not a single technology but a four-module architecture, each component addressing a distinct operational challenge while functioning as part of an integrated system.

The system's foundational layer is underground Wi-Fi coverage, and this is where the platform introduces a capability that conventional mine operators frequently underestimate: network visibility. Rather than assuming Wi-Fi coverage is uniform throughout a mine's footprint, the Network Awareness component maps actual access point coverage across the entire underground environment. Gaps in coverage are identified before they become safety vulnerabilities during emergencies.

This visibility matters because underground Wi-Fi networks are not static. New development headings, equipment repositioning, and structural changes continuously alter the acoustic and electromagnetic environment through which signals must travel. A system that cannot see its own network blind spots cannot guarantee delivery of emergency communications to every worker.

How Does an Emergency Event Trigger the System?

The operational sequence during an emergency illustrates why the acknowledgement functionality represents the most significant advance over legacy systems:

1. Control room detects alarm activation and initiates emergency response protocol
2. Zone-targeted mass emergency message dispatched to all personnel in affected and adjacent areas
3. Workers receive alerts simultaneously on work phones and vehicle-mounted Onboard displays
4. Personnel acknowledge message receipt, transmitting real-time status confirmation to the control room
5. PocketMine provides 3D navigation guidance toward nearest rescue chambers
6. Control room operators maintain live positional tracking of all unconfirmed personnel until evacuation is verified complete

The acknowledgement step closes what has historically been the critical information gap in underground emergency response. Without confirmation of receipt, control rooms operating legacy systems had no reliable mechanism to distinguish between workers who had received and acted on an evacuation alert and those who had not. Rescue team deployment decisions were consequently made with incomplete situational awareness.

With real-time acknowledgement, priority resource allocation becomes possible. Unconfirmed personnel can be immediately flagged for targeted rescue team deployment rather than requiring teams to systematically search entire zone segments.

LKAB's Kiruna and Malmberget Deployment Strategy

The implementation approach chosen by LKAB reflects a deliberate philosophy about how complex technology should be introduced into high-stakes production environments. Rather than a simultaneous full-scale cutover, the deployment runs in two parallel tracks.

Kiruna serves as the primary active production rollout site, where the system operates within the full complexity of a live, large-scale iron ore operation. Malmberget is running parallel testing and structured drill exercises, validating system performance across a second distinct geological and infrastructure environment before full integration.

This phased approach is not simply risk management. It is a recognition that controlled test conditions, no matter how rigorously designed, cannot fully replicate the operational variables present in a working mine. Shift-change communication loads, peak equipment traffic periods, variable coverage zones near active development headings, and the unpredictable behaviour of a workforce moving through complex three-dimensional space under normal production conditions all generate system stresses that laboratory testing cannot anticipate.

Running the new digital infrastructure alongside legacy systems before full cutover allows LKAB and Epiroc to identify real-world performance gaps that would otherwise only surface during an actual emergency, precisely the moment when a gap is least acceptable.

Why the On-Site Development Model Changed the Outcome

One of the less-discussed structural innovations in this partnership is not technological but organisational. Epiroc embedded development engineers directly within LKAB's underground operations throughout the project lifecycle.

Mikael Winnebäck, IT Project Manager at LKAB, has emphasised that having developers physically present in the mine environment during the project was critical to achieving a successful outcome, noting that this proximity allowed the engineering team to develop a genuine understanding of the operational complexities and observe firsthand how the solutions performed in a real working environment (Canadian Mining Journal, May 7, 2026).

This model inverts the conventional vendor-client technology deployment relationship. In standard deployments, engineers design against a specification document, deliver a system, and hand over documentation. The feedback loop between operational reality and system design runs through formal change request processes that introduce latency and often lose nuance in translation.

Embedded co-development removes that latency. When an engineer observes that Wi-Fi signal strength drops in a specific tunnel section during shift changes due to equipment clustering, that observation translates directly into infrastructure adjustment, not a ticket in a project management system. In addition, data-driven mining operations of this nature benefit enormously from having engineers embedded where data is actually generated.

The SUM Initiative: The Broader Context

The LKAB-Epiroc safety system deployment does not exist in isolation. It is part of the Sustainable Underground Mining (SUM) initiative, a multi-partner research and development programme launched in 2018 centred on LKAB's Konsuln test mine.

The SUM programme is built around a specific and challenging objective: achieving safe coexistence between human workers and autonomous, battery-electric equipment in underground environments at depths exceeding 2,000 metres, while simultaneously reducing the carbon footprint of deep mining operations.

The partner ecosystem assembled to pursue these objectives spans the full technology stack of a modern underground mine:

The Autonomy-Safety Dependency Nobody Talks About

There is a critical but frequently overlooked interdependency within the SUM programme's objectives. The push toward autonomous mining trucks and other autonomous underground equipment — vehicles operating without direct human control through mine corridors — creates a safety paradox that receives insufficient attention in public discussions of mining automation.

As machine autonomy increases, the risk profile for any human worker in the same environment changes fundamentally. An autonomous loader or haul truck does not possess the contextual awareness of a human operator who can recognise an unusual situation, make a judgement call, and take evasive action. The safety of autonomous mixed-traffic environments depends entirely on the quality of real-time positional awareness available to the systems managing vehicle routing and exclusion zones.

Without precise, real-time 3D positioning for every human worker underground, autonomous vehicle systems cannot maintain safe dynamic exclusion zones. Zone-based approximation, which might place a worker within a 200-metre tunnel segment, cannot provide the location precision required to prevent a collision between an autonomous machine and a person on foot.

This creates a hard dependency: autonomous underground mining is not safely scalable without first solving the real-time human tracking problem. The Epiroc safety system deployment at LKAB is therefore not just a safety upgrade, it is prerequisite infrastructure for the autonomous mining ambitions that the broader SUM programme is designed to achieve.

Comparing the Technology Landscape

The underground personnel tracking market includes several competing technology approaches, each with distinct performance characteristics relevant to mine operators evaluating their options.

The Epiroc platform's competitive positioning rests not on any single technology component but on the integration of positioning, communication, navigation, and acknowledgement functions within a unified architecture that operates on Wi-Fi infrastructure many mines are already deploying for other operational purposes.

The practical implication for mine operators is that where underground Wi-Fi infrastructure already exists, the marginal cost of adding personnel tracking, zone-based emergency communication, and mobile navigation is substantially lower than building a parallel dedicated positioning network. This infrastructure leverage effect makes the economics of adoption more accessible than competing approaches that require purpose-built hardware networks.

What This Means for the Global Industry

The Kiruna and Malmberget deployments carry relevance well beyond northern Sweden. Deep underground mining operations face similar structural challenges regardless of geography: the absence of GPS, the complexity of three-dimensional navigation, the life-safety consequences of delayed emergency response, and the growing pressure to integrate autonomous equipment into environments where human workers remain present.

Several converging dynamics are accelerating the case for real-time underground safety infrastructure across major mining jurisdictions. Furthermore, the broader shift toward mining energy transformation and electrification is creating additional pressure to modernise all layers of operational infrastructure simultaneously:

• Regulatory trajectory: Workplace safety authorities in multiple jurisdictions are progressively raising the standard for personnel accountability in underground environments. Proactive investment in real-time tracking systems positions operators ahead of these emerging compliance thresholds rather than behind them.
• ESG scrutiny: Institutional investors and sustainability rating frameworks are applying increasing scrutiny to workforce safety metrics as indicators of operational governance quality. Fatality rates, lost-time injury frequencies, and emergency response capability are becoming material considerations in capital allocation decisions.
• Insurance and liability: Demonstrable investment in advanced emergency response capability creates a defensible record for insurers assessing risk exposure and for legal purposes in the event of a workplace incident.
• Operational continuity: Incident-related downtime in deep mining operations carries significant production cost. Faster emergency response and reduced injury severity directly contribute to mine availability.

Hans Wahlquist, Epiroc's Global Director for Product Management Digital Solutions, has described digital applications as a transformative development for accident prevention and rapid personnel evacuation during emergencies, characterising the LKAB partnership as a meaningful step toward a more intelligent and efficient future for underground mining (Canadian Mining Journal, May 7, 2026).

Andreas Ericson, General Manager at Epiroc, has reinforced this view, noting that the LKAB-Epiroc deployment demonstrates the potential of digital transformation in the mining sector and reflects LKAB's position at the leading edge of workforce safety practice. This sentiment aligns with the broader momentum around AI-powered mining efficiency reshaping how operators approach both productivity and safety infrastructure.

Frequently Asked Questions

Which LKAB Mines Are Included in the Epiroc Safety System Rollout?

The system is being deployed across LKAB's two underground iron ore operations in northern Sweden: Kiruna, which is the primary active production rollout site, and Malmberget, where parallel testing and structured emergency drill exercises are currently underway ahead of full integration.

How Does the New System Improve on LKAB's Previous Approach?

The legacy system relied on physical tags and zone-based divisions to estimate worker locations within broad mine segments. The Epiroc platform replaces this with precise real-time 3D positioning for both personnel and vehicles, adds targeted zone-specific emergency communication, provides mobile 3D navigation via PocketMine, introduces vehicle collision awareness through the Onboard module, and delivers message acknowledgement functionality that confirms worker status to the surface control room in real time.

Why Is Wi-Fi Infrastructure Central to the System's Operation?

The entire platform depends on a reliable underground Wi-Fi network. The Network Awareness module maps actual coverage across the mine footprint, identifying signal gaps before they compromise tracking reliability. Consistent Wi-Fi coverage is a foundational requirement, not an optional enhancement, because the positioning, communication, and navigation functions all operate over this network.

How Does the Acknowledgement Feature Change Emergency Response?

Worker acknowledgement of emergency alerts provides control room operators with real-time confirmation of personnel status. This allows responders to immediately identify individuals who have not confirmed receipt, enabling targeted rescue team deployment rather than requiring systematic searches of entire zone segments. It consequently transforms emergency response from a broadcast model into a two-way status-confirmation loop.

Is This Technology Applicable Outside Sweden?

Epiroc positions its digital safety portfolio as applicable to deep underground mining operations globally. The LKAB partners with Epiroc on an underground safety system that provides a high-profile reference case in a demanding production environment, which other operators evaluating the transition from legacy zone-based systems to integrated real-time platforms can draw on.

How Long Has the LKAB and Epiroc Partnership Been Active?

The formal technology collaboration has roots in the Sustainable Underground Mining initiative launched in 2018, with the safety system development and production rollout progressing through to the current deployment phase in 2025 and 2026.

Key Takeaways for the Mining Industry

The LKAB-Epiroc deployment offers several principles worth examining by any operator managing underground workforces:

• 3D precision is not an upgrade, it is a prerequisite: As mines deepen and autonomous equipment becomes more prevalent, zone-level approximation is structurally insufficient for the safety requirements of modern underground operations
• Acknowledgement closes the loop: The single most operationally significant advance in this system is the ability to confirm, in real time, which workers have received and responded to an emergency alert, a capability that transforms evacuation management from estimation to evidence
• Co-development outperforms conventional deployment: Embedding engineers within production environments during system development produces materially better outcomes than specification-driven remote deployment, particularly for complex, safety-critical infrastructure
• Phased parallel deployment reduces risk: Running new and legacy systems simultaneously before full cutover identifies real-world performance gaps before they matter most
• Safety and autonomy are interdependent: Real-time human tracking is not separable from the autonomous mining ambition. It is the foundation upon which safe human-machine coexistence in deep underground environments must be built
