Background

Inaglinsky-1 coal mine (Шахта Инаглинская-1) is an underground mine in Republic of Sakha, Russia.

It is part of the Inaglinskiy Mining Complex (Инаглинский ГОК) which also includes the Inaglinskiy open-pit coal mine and the proposed Inaglinsky-2 coal mine. The Inaglinsky-1 coal mine is operated by GOK Inaglinsky JSC, which is owned by Kolmar.

The underground mine was commissioned in September 2020, together with the washing plant Inaglinskaya-2. Its capacity is 6 million tonnes (Phase 1). The construction of Phase 2 (Inaglinsky-2 coal mine) with capacity of another 6 million tonnes is under way. When Phase 2 is commissioned, the Inaglinsky mine will be the largest underground mine in Russia.

Coal from the Inaglinsky mining complex is exported via the VaninoTransUgol coal terminal, which is owned by Kolmar and began operating in 2020. The terminal, together with the mines and the washing plant, completes the creation of the unified production and logistics complex. Coal exports are targeted at the Asian Pacific region, in particular at China and Japan. About 70% of coking coal shipments are to China. Kolmar is also conducting contract negotiations with the largest state-owned and private metallurgical companies in India.

In December 2024 it was reported that the mine extracted 7 million tonnes of coal. It was not clear whether any coal was already extracted from the new mine Inaglinsky Coal Mine 2, it was still referred to as being 'in construction'. This production level has marked overall 25 Mt production from the mine since it started operations. Just a few days later, rock collapse occurred in the mine, with one fatality and one miner injured. Operations of GOK Inaglinsky were said to be suspended for 90 days following this tragic event.

Inaglinsky Complex

The strategy of Kolmar is to expand the mining complex. Coal from the Inaglinsky mining complex is exported via the VaninoTransUgol coal terminal, which is owned by Kolmar and began operating in 2020. The terminal, together with the mines and the washing plant, completes the creation of the unified production and logistics complex. Coal exports are targeted at the Asian Pacific region, in particular at China and Japan. About 70% of coking coal shipments are to China.

In 2025, Kolmar’s total coal production amounted to 10.4 million tonnes across its two mining complexes — Inaglinsky and Denisovsky (comprises Denisovsky Central Coal Mine, Denisovsky Vostochny Coal Mine and Denisovsky Surface Coal Mine).

Safety Incidents

In 2024, a fatal accident occurred at the Inaglinsky underground mine (JSC GOK Inaglinsky), part of Kolmar. A rock collapse resulted in the death of an underground drifter, while a mining machine operator sustained minor injuries. Following the incident, the Investigative Committee of Russia for the Republic of Sakha (Yakutia) initiated a criminal case under Part 2 of Article 216 of the Criminal Code of the Russian Federation (violation of safety rules during mining operations resulting in death by negligence).

Coal Mine Boundaries and Methane Sources

Global Energy Monitor researchers have identified coal mine boundary/boundaries and potential sources of coal mine methane (CMM) for this mine. These research results can be used to drive CMM attribution and mitigation efforts, particularly when combined with remotely sensed methane plume locations and mine ownership data. Explore the results with the embedded map at the top of this page by clicking on the mine boundary polygon or the CMM placemarkers to reveal more details. A detailed description of this research can be found in Coal Mine Boundaries and Methane Sources. This data is also available as a downloadable companion dataset to the Global Coal Mine Tracker and the Global Methane Emitters Tracker.

ID	Notes
M1265.B1	This mine operates under four adjacent subsoil land-use licenses(GOK Inaglinskiy), ЯКУ 04565 ТЭ, ЯКУ 04564 ТЭ, ЯКУ 04639 ТЭ and ЯКУ 05093 ТЭ, as identified through the Preliminary Environmental Assessment of the Proposed Adjustment to the Inaglinskaya Coal Mine Construction Project (Предварительная экологическая оценка намечаемой корректировки проекта строительства угольной шахты «Инаглинская»), https://www.archive.org/details/inaglinskaya-coal-mine, page 5, 2021. The license ЯКУ 04565 ТЭ was issued on November 30, 2015, and is valid until December 25, 2026. The license ЯКУ 04564 ТЭ was issued on November 30, 2015, and is valid until June 1, 2025.The license ЯКУ 04639 ТЭ was issued on April 22, 2016, and is valid until April 30, 2041. The license ЯКУ 05093 ТЭ was issued on September 28, 2016, and is valid until February 24, 2032. License issuance and expiration dates were identified through the Rosnedra license registry, “Register of Subsoil Use Licenses as of January 1, 2024” («Реестр лицензий по состоянию на 01.01.2024 г.»), https://www.archive.org/details/register-of-subsoil-use-licenses-as-of-january-1-2024.The boundary for license ЯКУ 04565 ТЭ was extracted from the NedraExpert portal at https://web.archive.org/web/20251223182237/https://www.nedraexpert.ru/license/135788?ysclid=mjiwunfser782625186. The boundary for license ЯКУ 05093 ТЭ was extracted from the NedraExpert portal at <url>. Polygon boundaries for subsoil licenses ЯКУ 04564 ТЭ and ЯКУ 04639 ТЭ were georeferenced using the Preliminary Environmental Assessment of the Proposed Adjustment to the Inaglinskaya Coal Mine Construction Project («Предварительная экологическая оценка намечаемой корректировки проекта строительства угольной шахты «Инаглинская»), page 94, https://www.archive.org/details/inaglinskaya-coal-mine, 2021. The resulting mine boundary represents the outer perimeter of these four adjacent license areas. The approximate area of the resulting boundary is 170 square km.
