1. GENERAL INFORMATION ABOUT THE MINE Legal status of the mine: Mine name: Technical unit "Zarya mine." Mine status: technical unit. Legal address: 86500, DPR, the city of Snezhnoye, st. Lenin, 32. Phone (06256) 56682. Fax (06256) 5-55-65 Name of RP which includes mine: RP Torezanthracite. General information about the mine: Year of commissioning - 1927; The year of the last reconstruction is 1972; Design capacity, thousand tons - 910; Annual production capacity as of 1.01.2015, thousand tons - 520; Industrial reserves for 01.01.2015, thousand tons. – 12885; Coal brand, purpose -A (anthracite), energy; Symbols and geological capacity of strata that are worked out - h6 (0.8-1.05), h7 (0.8-1.5); Angle of formation incidence, hail - 3 ° -16 °; Gas mine category (methane) - supercategory; Maximum development depth, m - 990; Formation preparation scheme - panel, horizontal; The development system is pillar in extension, in rebellion, fall, combined, continuous with workings behind the lavas. Operating mode: number of working days per year - 354; the number of shifts in coal production is 3. Planned coal production in 2016 amounted to 610.0 thousand tons. Carrying out preparatory workings of 3800 m, ash content of mined coal is 44.9%. As of January 1, 2015, the balance reserves of coal are 20.032 million tons, including industrial coal reserves - 12.885 million tons. The main part of the balance sheet reserves for the formations is located at depths up to 900 m. Currently, mining is carried out at a depth of 700 to 990 m. The weighted average depth of reserves development in 2016 was 850 m. Mined coals belong to brands A, which are energy in their quality characteristics, which determines the serious strategic importance of the Torezanthracite RP in the market of suppliers of raw materials for energy. Within the mine field, the formations are distinguished by the complexity of the geological structure. The capacity of the formations under development ranges from 0.8 to 1.25 m with incidence angles from 3 ° to 16 °. Planned ash content for 2017 - 44%. For 1.01.2017 the number of active treatment faces is - 2. The treatment faces are equipped with KD-80 mechanized supports. The scavengers of the UKD 200-250 are used. The annual volume of opening and preparing works in 2014 is 2,539 km. Preparatory bottoms are equipped with rock loading machines 2PNB-2B, 1PPN-5. Treatment works Currently, two lavas are in operation at the mine: lava No. 16 pl.h7 and 3 eastern lava pl. h6. The development of lava No. 16 is carried out according to a combined system for stretching. The 3rd eastern lava is worked out according to a continuous development system for propagation.

As locomotives, battery electric locomotives 2AM-8D, AM-8D are used. Coal is transported in section trains PS-3.5, rock - in wagons VG-2.5. For inclined workings, the transportation of rock and coal is carried out using belt conveyors 1L100 and 1L80. Transportation of coal from the lavas is carried out by conveyors SP26 and SP250.
