The coal mines of Qarmet JSC (former ArcelorMittal Temirtau) are located in the Karaganda Coal Basin. The basin is more than 3,000 square kilometers and was formed by strata of Upper Devonian and Carbonic ages, Mesozoic and Cainozoic formations. Due to structural peculiarities, the coal basin is divided into three geology-based mining areas: Karagandinskiy, Sherubay-Nurinskiy and Tentekskiy.Karaganda basin is located on the area of the same name and in the center of this region. Carbon coal-content area occupies the land of about 2000 km2 at the total thickness 4000m. Four synclines are notable in the basin: Tentek, Sherubainur, Karaganda and Verkhnesokursk, first three of them make an industrial part of basin and are studied full enough up to the depths 700-1300m. Productive sediments are represented by Ashlyarik, Karaganda, Dolinsk and Tentek series which contain up to 30 coal seams with the total working thickness 40m, coal ash content varies within the limits of 10-35 % with the tendency of reduction upwards the section. The most-widely spread are coals of types from hvBb to mvb. Karaganda basin is considered as a high gas content and gas content seams intensively grow from the beginning of methane zone up to 400-500m reaching 15-20 m3/t, and are more stabilized on the depth within the limits of 22-27 m3/t. Gas weathering zone depth varies within the limits of 60-250 m.The field of Lenina mine is represented by an asymmetrical synclinal fold that is complicated by plicative and disjunctive imperfections and faults. The geological structure of coal-bearing strata is represented by argillites, siltstones and sandstones of carbonic age. The productive layer is presented by seams of Dolinskaya suite: D1, D3, D5, D6, D9, D10. All of the seams are considered dangerous with outbursts. The main coal grade is KZh with rare1K Coke and 2K Coke.
