ALROSA Fortifies Mine Safety Protocols Following Mir Mine Incident
In a decisive move to reinforce its commitment to operational safety, Russian diamond mining behemoth ALROSA has established a specialized ad hoc expert group. This initiative, launched in the wake of significant industry events, aims to conduct a thorough and exhaustive safety assessment across all its underground mining operations. The comprehensive evaluation is mandated to conclude by September 1, 2017, underscoring the urgency and strategic importance placed on this critical undertaking.
Proactive Safety Assessment Across Key Underground Mines
Beyond the deeply impacted Mir mine, ALROSA operates several other vital underground diamond mining facilities. These include the International, Aikhal, and Udachny mines, all of which fall under the purview of this new, stringent safety review. The expert group’s mandate, as detailed in an order signed by ALROSA President Sergey Ivanov, extends to a multi-faceted analysis of potential risks and existing preventative measures.
A primary focus of the assessment is to meticulously evaluate the potential impact of surrounding water bodies on mine workings. This includes scrutinizing the integrity of existing barriers and the efficacy of measures implemented to prevent water inflows from abandoned quarries – a perennial and formidable challenge in deep underground mining operations. Water ingress poses a significant threat, not only to equipment and infrastructure but, more critically, to the lives of miners. Therefore, a robust hydrogeological and engineering assessment is paramount to mitigating these risks effectively.
Composition and Expertise of the Safety Task Force
ALROSA’s statement highlights the impressive breadth and depth of expertise within this newly formed group. It comprises a blend of both independent experts, ensuring an unbiased and objective review, and key internal specialists from ALROSA’s top ranks. This formidable team includes the company’s chief engineer, chief geotechnician, chief hydrogeologist, and the head of the underground mining department. Further enhancing its technical capability, the deputy chief surveyor and the chief engineer of the esteemed Yakutniproalmaz Institute also lend their invaluable experience. This combination of internal knowledge and external oversight is designed to yield a comprehensive and credible safety audit, reflecting the highest industry standards.
The scope of the group’s detailed assessment is extensive. It encompasses:
- An evaluation of compliance between current mining operations and original project designs, particularly concerning adherence to the boundaries of hazardous mining zones located near water bodies. Strict adherence to these boundaries is non-negotiable for maintaining geological stability and preventing unforeseen water breaches.
- A thorough examination of the condition of the safety lock system, which is crucial for controlling water flow and isolating potential hazards within the mine. The integrity and functionality of this system are vital for rapid response and containment in an emergency.
- An appraisal of the performance and reliability of the main dewatering complex. Effective dewatering is the backbone of underground mine safety, continuously removing groundwater and preventing flooding, which can otherwise compromise structural stability and operational integrity.
- An assessment of the state of mine workings situated in close proximity to safety pillars. These pillars are critical structural elements designed to support overlying strata and prevent collapses, making their condition a key indicator of overall mine stability.
- A diligent search for and analysis of any uncontrolled water manifestations, which could signal deeper hydrogeological issues or structural weaknesses requiring immediate attention. Identifying and addressing these early can prevent catastrophic failures.
A Proactive Stance on Industrial Safety and Risk Mitigation
President Sergey Ivanov reiterated ALROSA’s ongoing commitment to industrial safety, noting that a comprehensive audit of the company’s entire industrial safety system had been underway since May, following a decision by ALROSA’s Supervisory Board. He emphasized that the current safety assessment forms an integral part of this broader internal exercise. The objective, as Ivanov articulated, is to proactively “identify (any) shortcomings” within existing safety protocols and operational practices, and crucially, “take prompt measures to eliminate them.” This proactive rather than reactive approach is a cornerstone of modern, responsible mining.
Ivanov clarified the distinct roles in the aftermath of the Mir mine accident: “The final and complete analysis of the causes of the accident at the Mir mine should be prepared by a commission of Rostekhnadzor.” Rostekhnadzor, as Russia’s Federal Service for Environmental, Technological, and Nuclear Oversight, is the official regulatory body responsible for such investigations. However, ALROSA’s internal initiative demonstrates a commitment that transcends regulatory compliance. Ivanov stated, “Nevertheless, we plan to conduct our own assessment of the situation at all other mines of the company without waiting for the conclusions of the commission, and in case of identifying shortcomings, to take prompt measures to eliminate them.” This dual approach allows ALROSA to immediately address potential vulnerabilities across its operations while awaiting the definitive findings of the official inquiry.
Update on Rescue Operations at the Mir Mine
The safety assessment announcement was accompanied by an update on the status of the highly challenging rescue operations at the Mir mine. The emergency response center, acting as the coordinating body, made the difficult decision to cease rescue efforts within the mine working on the -310 meters level. This critical decision was necessitated by severe conditions: the level was flooded with water exceeding one meter in height, rendering descent impossible and posing an unacceptable, life-threatening risk to rescue personnel. Tragically, four of the eight missing miners were believed to have been located at this level, based on the last signals received from their electronic tags.
Despite the cessation of operations at the -310m level, ALROSA confirmed that all available resources and efforts of the dedicated rescue teams are now concentrated on clearing rubble and searching for the remaining missing miners on the -210 meters level. This phase of the operation, however, presents its own formidable set of challenges. The statement outlined complexities arising from the presence of oversized pieces of rock and various metal structures and pipes of different diameters, significantly impeding progress. Furthermore, many of the working areas on this level are also flooded, filled with mountain mass, and entangled with metal structures, making the task exceptionally arduous and perilous for the rescue teams. Despite these profound difficulties, the update also provided a crucial piece of reassuring information: the ventilation mode within the mine remained normal, and mine rescue work was continuing with unwavering resolve.
ALROSA’s Operational Resilience: Production Targets Unaffected
In a related and significant development, Igor Sobolev, ALROSA’s first deputy chief executive, provided a crucial clarification to the media regarding the company’s operational stability. He confirmed that despite the severe accident at the Mir mine, it would not impact ALROSA’s ambitious 2017 production target of 39 million carats. This assertion underscores the company’s robust operational planning and diversified asset base.
Sobolev explained that any potential decline in production volume specifically from the Mir mine would be strategically compensated for by an increase in production at ALROSA’s other operational mines. This flexibility and capacity within its wider portfolio allow ALROSA to absorb shocks from individual site incidents, maintaining overall output and market commitments. Such a demonstration of operational resilience is vital for maintaining investor confidence and ensuring stable supply to the global diamond market. It also highlights the strategic importance of ALROSA’s diverse mining assets beyond just its most prominent operations.
The events at the Mir mine, while tragic, have undoubtedly catalyzed a heightened focus on safety and operational integrity across ALROSA’s entire infrastructure. The establishment of the expert safety group and its extensive mandate signal a proactive, preventative approach designed to fortify the company’s defenses against future incidents and underscore its long-term commitment to responsible and safe diamond mining practices. This commitment extends beyond immediate crisis management, aiming for continuous improvement in all aspects of industrial safety and risk management, setting a precedent for the broader industry.
