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.
