JSC Mining and Coal Preparation Complex Denisovskiy (JSC GOK Denisovskiy). Develops the reserves of Denisovskiy stone coal deposits (Central and Eastern part) within the license areas.

GOK Denisovskiy includes:

1. Denisovskaya mine (operational) - 32.1 Mt of coal reserves for underground mining
2. Denisovskaya Eastern mine (under construction) - 4 Mta of coal
3. Denisovskiy open pit (operational)
4. Denisovskiy Eastern area - 174.1 Mt of coal reserves for open-pit and underground mining

Today, Kolmar is the leader among Russian companies in terms of room-and-pillar mining efficiency, which is applied at Denisovskaya mine (GOK Denisovskiy). Room-and-pillar method was not used at deposit below 200 meters in Russia; Kolmar is the first company to obtain permission to use this technique and has applied this method for mining coal at deeper deposits. In order to master this technology, several production crews underwent training at the best mines in the world — including mines in Australia, Germany, the USA and South Africa.

Today Kolmar is mining coal at an industrial scale with three sets of room-and-pillar mining equipment and ensures the production volume over 2 Mta.
