In a significant stride towards enhancing operational safety and environmental stewardship, ALROSA, the world’s leading diamond mining company, has initiated the implementation of an advanced Automated Wireless Monitoring System (AWMS) at the critical waterworks of its Aikhal Division. This pioneering move marks a pivotal transition from conventional manual oversight to an intelligent, real-time automated control system, fundamentally reshaping the management of tailings storage facilities. The primary objective is to dramatically reduce the risk of potential emergencies and elevate the safety standards surrounding the tailings storage facility at Processing Plant #14, reinforcing ALROSA’s commitment to responsible mining practices.
Revolutionizing Tailings Management with Automated Wireless Monitoring
The Automated Wireless Monitoring System (AWMS) represents a cutting-edge technological leap in the realm of industrial safety and environmental protection within the mining sector. At its core, the system comprises an intricate network of sophisticated sensors strategically positioned at the existing measurement points across the expansive tailings dump and associated infrastructure of Processing Plant #14 at the Aikhal Division. This comprehensive network is engineered to provide continuous, precise data, offering an unparalleled level of insight into the dynamic conditions of the facility.
The AWMS integrates a diverse array of monitoring instruments designed to capture critical environmental and structural parameters. Specifically, it includes 33 thermometric wells and 31 piezometric wells, alongside various level gauges deployed within both the tailings dump and the crucial storage pond. Each of these components plays a vital role in painting a complete picture of the facility’s health and stability:
- Thermometric Wells: These wells are equipped with sensors that continuously measure the temperature of the soil within and around the enclosing structures of the tailings facility. Soil temperature data is critical for identifying potential anomalies such as frost heave, thawing, or unusual heat signatures that could indicate subsurface seepage or structural instability. Understanding temperature fluctuations is essential in permafrost regions, where changes can significantly impact ground stability.
- Piezometric Wells: Piezometers are instrumental in monitoring the pore water pressure within the tailings material and the dam structures. Elevated pore water pressure can drastically reduce the effective stress within the soil, significantly increasing the risk of liquefaction or slope failure. Real-time piezometric data allows engineers to assess the stability of the dam and detect early signs of potential issues that could compromise its integrity.
- Level Gauges: These devices are installed in the tailings dump and the storage pond to precisely measure water levels. Accurate water level monitoring is crucial for effective water management, preventing overtopping, ensuring adequate storage capacity, and understanding the overall hydrological balance of the facility. Fluctuations in water levels can also indicate changes in seepage rates or unexpected inflows.
Through the integration of these sophisticated components, the AWMS offers an holistic approach to monitoring. It allows for the continuous assessment of all key parameters governing the structure’s integrity, including the vital water levels in open reservoirs and the critical soil temperature of the enclosing structures. This integrated data collection provides a robust foundation for proactive risk management.
Unlocking Unprecedented Safety and Efficiency: The AWMS Advantage
The implementation of an automated wireless monitoring system heralds a new era of safety and operational efficiency for ALROSA. Vyacheslav Zubarev, chief engineer of the Aikhal Division, underscores the transformative impact of this technology:
“Implementation of AWMS allows receiving real-time information on the state of the hydraulic system, quickly assessing the dynamics of changes occurring there and act immediately in response. This makes the tailings management more stable and eliminates emergencies that could harm the Aikhal plant’s and settlement’s infrastructure and the region’s ecology.”
This statement encapsulates the core benefits derived from such advanced systems. The ability to receive real-time information is paramount. Instead of relying on periodic, manual readings that offer only snapshots in time, the AWMS provides a continuous stream of data. This constant influx of information allows for an immediate and accurate assessment of any changes, no matter how subtle, occurring within the hydraulic system. This responsiveness translates into several critical advantages:
- Proactive Risk Mitigation: Real-time data enables engineers and operators to identify potential issues as they emerge, rather than discovering them after they have escalated. This proactive approach significantly enhances the capacity to mitigate risks before they develop into serious threats.
- Rapid Emergency Response: In the unlikely event of an anomaly or a developing issue, the system’s ability to provide immediate alerts allows for swift and targeted interventions. This rapid response capability is crucial in preventing minor incidents from spiraling into major emergencies, thereby protecting both human lives and valuable assets.
- Enhanced Structural Stability: By continuously monitoring critical parameters like pore water pressure and soil temperature, the AWMS provides deep insights into the structural integrity of the tailings facility. This continuous oversight ensures that the structures remain within safe operating limits, significantly reducing the risk of catastrophic failures.
- Environmental Safeguarding: Tailings storage facilities inherently pose environmental risks if not managed meticulously. The AWMS allows for early detection of seepage or other environmental concerns, enabling prompt remedial actions that prevent potential contamination of local ecosystems and water sources. This commitment to environmental protection is a cornerstone of responsible mining.
- Optimized Resource Allocation: With precise data guiding decision-making, ALROSA can optimize the allocation of resources for maintenance and operational activities. This data-driven approach ensures that interventions are timely and effective, leading to improved operational efficiency and cost savings in the long run.
Ultimately, the AWMS fosters a more stable and secure tailings management framework, safeguarding the critical infrastructure of the Aikhal plant, protecting the surrounding settlement, and preserving the delicate ecology of the region. It’s a testament to ALROSA’s forward-thinking strategy in merging technological innovation with corporate responsibility.

The deployment of the Automated Wireless Monitoring System at the Aikhal Division marks a significant milestone as it represents the first implementation of such a comprehensive and sophisticated system within ALROSA’s extensive operations. This initiative positions the Aikhal Division not just as a site for resource extraction but also as a hub for technological innovation and a pioneer in adopting industry-leading safety standards. The decision to introduce this system reflects ALROSA’s strategic commitment to embracing advanced technologies to enhance safety, efficiency, and environmental performance across its entire operational footprint.
The installation phase for the AWMS is currently well underway, with diligent efforts focused on deploying the intricate network of sensors and robust power sources (batteries) across the designated monitoring points. This foundational work is critical to establishing the robust data collection infrastructure required for continuous, reliable monitoring. While the physical installation progresses, parallel efforts are dedicated to the finalization of regulatory documents and operational protocols. This comprehensive approach ensures that the system is not only technologically sound but also fully compliant with all pertinent safety and environmental regulations, and seamlessly integrated into the division’s operational framework. The complete installation of equipment and the finalization of all necessary regulatory documents are projected to be concluded by the end of 2020, paving the way for full operational capability.
Scaling Innovation: A Future of Enhanced Safety Across ALROSA
The implementation at the Aikhal Division is not an isolated project but rather a blueprint for a broader, company-wide transformation in hydraulic facility management. ALROSA has articulated clear plans to extend the deployment of similar automated monitoring equipment to its other hydraulic facilities in the near future. This strategic scalability underscores the company’s long-term vision for a unified, technologically advanced approach to safety and environmental oversight across all its operations.
Historically, the monitoring of these critical facilities relied heavily on manual processes. Various divisions, in conjunction with the specialized expertise of the Yakutniproalmaz Institute, conducted on-site measurements and inspections according to pre-approved schedules. While these manual methods provided essential data, they inherently possessed limitations. Manual monitoring is labor-intensive, time-consuming, and offers data points only at specific intervals, which can lead to delays in detecting rapidly developing issues. Furthermore, the accuracy and consistency of manual readings can be subject to human variability and the challenges posed by harsh environmental conditions inherent in mining regions.
The transition to automated wireless monitoring represents a paradigm shift from this traditional approach. It eliminates the need for frequent human exposure to potentially hazardous areas, improves the frequency and accuracy of data collection, and liberates skilled personnel to focus on higher-value tasks such as data analysis, predictive modeling, and strategic planning, rather than routine data acquisition. This digital transformation not only enhances safety and efficiency but also positions ALROSA at the forefront of sustainable mining practices, leveraging technology to mitigate risks and foster a resilient operational environment. The experience gained at Aikhal will serve as an invaluable model, ensuring a smooth and effective rollout of AWMS across other critical sites, solidifying ALROSA’s commitment to safety, technological advancement, and environmental stewardship for years to come.
