How Danko Spark is Helping Mines See Risk Before It Happens
Fatigue remains one of the most persistent and difficult safety risks in mining. Unlike visible hazards underground, fatigue builds quietly over time, and often long before anyone notices the warning signs. A worker may arrive on shift appearing alert, while sleep deficits, poor recovery and physiological stress have already been accumulating for days.
To address this challenge, Danko Spark has partnered with Polar to develop a continuous fatigue and wellness monitoring platform purpose-built for mining and high-risk industrial environments. Using Polar 360 wearable devices and a custom-built software ecosystem, the platform gives mines a real-time, defensible view of workforce fatigue and recovery, before fatigue leads to incidents.
As software developers behind the platform and suppliers of Polar devices for the mining industry, Danko Spark has created a solution designed specifically for the realities of mine operations.
Watching for Fatigue Before Fatigue Causes the Incident
Traditional fatigue management systems rely heavily on pre-shift declarations, questionnaires or manual observations. The problem is that fatigue is rarely obvious in the moment.
Workers may under-report symptoms. Supervisors cannot see what kind of sleep or recovery a worker had the night before. Metrics like Heart Rate Variability (HRV), sleep debt and autonomic nervous system stress build gradually across rosters and swing cycles. By the time visible fatigue appears, the physiological deficit is often already several days deep.
This is where continuous monitoring changes the conversation.
Instead of relying on occasional wellness snapshots, the Danko Spark platform creates an always-on fatigue signal using data collected from Polar 360 wearables. The result is a continuous stream of worker wellness insights that allows sites to identify risk trends early, before a near-miss or incident occurs.
A Continuous Monitoring Platform Built for Mining
The platform aggregates wearable data at three operational levels:
- Individual worker monitoring
- Gang or crew-level analysis
- Site-wide fatigue and wellness visibility
Using Polar 360 devices, the platform automatically collects and analyses:
- Sleep duration and sleep stages
- Sleep efficiency
- Nightly recharge and recovery
- Autonomic nervous system recovery
- HRV (RMSSD measured against the worker’s personal baseline)
- Heart rate
- Daily activity and movement
- Step counts
- Training load and exertion
This data feeds directly into dashboards used by:
- Site managers
- Safety teams
- Occupational health personnel
- Operational leadership
At the same time, workers receive personalised weekly wellness reports built from the exact same data being monitored operationally. This creates transparency while encouraging proactive health and recovery behaviours.
The Lamproom Becomes the Data Hub
One of the biggest challenges with wearable technology is data syncing. Many wearable projects fail because they rely on workers remembering to open apps, connect devices or manage uploads themselves.
Danko Spark solved this problem by integrating syncing directly into the mining workflow through the lamproom.
As workers move through the lamproom, the system pulls:
- Sleep data
- Recovery metrics
- Activity data
- Wellness indicators
Everything uploads automatically in real time.
There is:
- No app to open
- No button to press
- No Wi-Fi handover to manage
- No disruption to operations
Managers can see live sync activity on dedicated dashboards, including:
- Per-device sync status
- Missing or partial syncs
- Device health indicators
This allows lamproom teams to intervene immediately if a sync issue occurs, helping mines maintain complete and reliable datasets without adding friction to worker routines.
An Exception Engine That Adapts to Each Worker
Fatigue risk is not identical across every employee. Underground operators, heavy equipment drivers and control-room staff all experience different workloads, recovery patterns and physiological baselines.
The Danko Spark platform addresses this through a highly configurable exception engine designed around personal physiology rather than fixed thresholds.
Each rule within the platform can be customised using:
- Threshold values
- Comparison operators
- Consecutive-day windows
- Lookback periods
- Severity levels
- Deduplication intervals
Rules can also be independently enabled or disabled depending on site requirements.
Most importantly, alerts are tied to the worker’s own physiological norms:
- Heart-rate alerts reference personal maximum heart rates
- HRV alerts reference rolling personal baselines
- Temperature alerts compare against recent weekly averages
This means the same engine can monitor very different workers on the same site without requiring separate rule systems for each group.
Mines can also configure site-wide defaults to match shift structures, roster cycles, workload demands and operational risk tolerance.
The result is a fatigue monitoring system that adapts to the workforce instead of forcing the workforce into rigid parameters.
Personalised Weekly Reports for Every Worker
The platform is not only designed for operational oversight; it is also built to support worker wellness directly.
Every employee receives a personalised seven-day wellness report summarising their sleep quality, activity levels, recovery trends and wellness patterns.
Using AI-generated analysis, the system transforms raw physiological data into plain-language insights and actionable recommendations specific to that worker’s actual week.
Instead of generic advice, reports provide meaningful observations based on real patterns and recovery trends.
Reports are accessible in two ways:
1) Through the in-platform dashboard used by management and occupational health teams
2) Via a tokenised PDF delivered through SMS
Workers simply tap the secure link to open their report, and no login is required. Links automatically expire after seven days for added security.
This creates a transparent feedback loop where the same data used operationally is also shared directly with the worker.

Why This Matters for Mining Operations
The biggest advantage of continuous fatigue monitoring is that mines gain visibility before incidents happen.
The platform changes three critical areas of fatigue management:
- Early Identification
Fatigue risk can be identified while it is building — not after a near-miss or incident investigation.
- Continuous Auditability
The platform creates a defensible audit trail showing what the site knew, when it knew it, and how fatigue indicators evolved over time for each worker.
- Reduced Reliance on Self-Reporting
Gang-level and site-level insights make emerging fatigue trends visible even when workers themselves may not report symptoms.
Because syncing happens automatically within the lamproom and monitoring thresholds adapt to individual physiology, operations continue normally while gaining a powerful new layer of workforce insight.
