Initially, the commercial resources of the Aikhal mine were estimated at 6.2 million tons of ore, with an expected operational end date between 2034 and 2035. The new development dramatically enhances these figures, showcasing the success of geological exploration and forward-thinking mine planning.

Operational Advantages and Uninterrupted Progress

One of the most compelling aspects of the Aikhal deep-level development project is its inherent efficiency. As Evgeny Denisov, Director of the Aikhal Mining and Processing Division, highlighted, “The project is also attractive due to no need for major re-equipment and no need to build new infrastructure, and so on. Development of deep levels and, accordingly, the extension of the mine life will allow keeping more than 500 jobs, which is crucial for our company.” This statement points to several critical advantages:

  • Cost-Efficiency: By leveraging existing infrastructure and minimizing the need for extensive new equipment, ALROSA can achieve significant cost savings. This optimizes the return on investment and makes the project economically more viable.
  • Reduced Implementation Time: Avoiding the complexities and delays associated with constructing entirely new surface infrastructure or procuring a full suite of specialized equipment allows for a smoother and potentially faster project rollout.
  • Environmental Responsibility: Utilizing existing facilities can also reduce the environmental footprint compared to starting a greenfield project. It aligns with modern mining practices that prioritize minimizing disturbance to natural landscapes.
  • Operational Continuity: The ability to seamlessly integrate the deep-level development into ongoing operations without major disruptions is a testament to ALROSA’s advanced mine planning and operational expertise.

The focus on maintaining existing infrastructure implies that the current operational setup at Aikhal is robust and adaptable enough to support the deeper mining activities. This speaks volumes about the original engineering design and the ongoing maintenance and modernization efforts at the mine.

Phased Implementation and Long-Term Outlook

The implementation of this extensive project is structured into clear, manageable phases, ensuring a systematic and safe approach to deep underground mining. The initial crucial step involves the construction and commissioning of the main haulage level at -100 meters. This critical piece of infrastructure is scheduled to be built and put into operation starting in 2020. The haulage level is the backbone of underground mining logistics, responsible for transporting mined ore to the surface or to processing facilities.

Concurrently, the year 2020 will also see the commencement of construction for mine openings that lead to the underlying beds. These openings are essential for accessing the deeper diamond-bearing kimberlite, allowing for exploration, development, and eventually, extraction. This parallel development strategy demonstrates an efficient use of resources and time, pushing the project forward on multiple fronts.

The culmination of these preparatory works will lead to the grand milestone: the start of extraction at the new horizons, specifically between -100 meters and -400 meters. This phase is meticulously planned to commence no later than 2027. The seven-year window from the initial construction phase to full extraction underscores the complexity and precision required for deep underground mining projects. It also highlights ALROSA’s commitment to thorough planning and safety protocols before initiating full-scale operations at these unprecedented depths for the Aikhal mine.
