The Future of Smart Tailings Facilities

As mining operations evolve, tailings storage facilities (TSFs) are no longer viewed as static structures. They are increasingly becoming smart, connected systems that integrate data, technology, and engineering judgement to improve safety, transparency, and performance.

The future of tailings management lies in smart TSFs facilities that continuously learn, adapt, and respond to changing conditions.

What Defines a Smart Tailings Facility?

A smart TSF combines engineering design, real-time data, and digital tools to support proactive decision-making throughout its lifecycle.

Key characteristics include:

• Continuous performance monitoring

• Data-driven risk assessment

• Early warning and alert systems

• Transparent reporting and governance

• Integration of human expertise with technology

Rather than reacting to problems, smart TSFs aim to anticipate and prevent them.

1. Real-Time Monitoring as the Backbone

Smart TSFs rely heavily on real-time instrumentation such as:

• Piezometers

• Inclinometers

• Water level sensors

• Flow meters

• Weather stations

These instruments feed live data into centralized dashboards, allowing engineers to detect abnormal trends early and take corrective action before risks escalate.

2. AI, Automation & Predictive Analytics

Artificial intelligence and advanced analytics are transforming raw monitoring data into actionable insight.

With predictive models, operators can:

• Forecast pore pressure changes

• Anticipate settlement and deformation

• Identify emerging instability patterns

• Prioritize maintenance and inspections

This shift from reactive monitoring to predictive risk management is a major step forward for TSF safety.

3. Digital Twins & Integrated Platforms

Digital twins create a virtual representation of a TSF that mirrors real-world behaviour.

By linking live monitoring data with numerical models, engineers can:

• Test “what-if” scenarios

• Evaluate design or operational changes

• Support safer decision-making

• Improve communication with stakeholders

Smart TSFs increasingly rely on integrated platforms that bring together design, monitoring, inspection, and reporting in one system.

4. Drones & Satellite Surveillance

Unmanned aerial vehicles and satellite technologies are now essential tools in smart tailings management.

They support:

• High-resolution surface mapping

• Deformation detection

• Dam crest and slope inspections

• Independent verification of stability

These technologies enhance site coverage, reduce safety exposure, and improve inspection frequency.

5. Transparency, ESG & Community Confidence

Smart TSFs also play a critical role in building trust.

With improved data quality and reporting systems, mining companies can:

• Demonstrate compliance with standards such as GISTM

• Share performance indicators with regulators

• Communicate risks more clearly to communities

• Strengthen ESG credibility

Technology is becoming a bridge between engineering performance and social licence to operate.

Looking Ahead

The future of tailings management is not just about stronger dams, it is about smarter systems.

Mines that invest in smart TSFs will be better positioned to:

• Reduce operational risk

• Improve regulatory compliance

• Adapt to climate uncertainty

• Protect people and the environment

Innovation is no longer optional; it is becoming central to responsible mining.
