Background

The Okino-Klyuchevsky Coal Mine (Окино-Ключевский разрез) is an operating surface coal mine in Buryatia Republic, Russia.

The mine is owned and operated by Ugolny Razrez LLC, a subsidiary of Inter RAO Electrical Generation.

The mine's coal mainly goes to Inter RAO's Gusinoozyorskaya power station, which is located 154 km away.

In 2022, residents of the nearby villages complained of tremors caused by the explosion activity at the mine, causing also windows breakage and gusts of dust.

A report from September 2023 referred to the plan to increase the mine's capacity to 4 Mtpa by 2030. The development agreement was signed between Inter Rao Electrical Generation and the government of Buryatia to cooperate in the development of the project to build two coal-fired power units at Gusinoozerskaya power station (No. 7 and No. 8) with a capacity of 230 MW each, further development of the mine to reach an annual production level of up to 4 million tonnes of coal, and construction of a railway line from the Okino-Klyuchevsky coal mine to the Kharankhoy railway station (East Siberian Railway) with a length of up to 80 km. The projects are to be implemented by the end of 2030.

As per news from October 2024, the mine's target capacity was now 3.8Mtpa to be achieved by 2028. Coal would be used by the new units proposed at Gusinoozyorskaya power station.
