Theological Mine Administration

Until 1900

In 1752–1757, 29 mines were discovered in the Theological Mining District (BSO), so in 1754 G. N. Posnikov’s expedition discovered copper ore deposits, later gold and iron ore were found. In the valley of the river Turyi, the mining village of Turyinsky Mines was founded. In 1752–1781, the owner of the mines and deposits of iron ore was Maxim Pohodyashin , including the Pokrovskoye, Kolongskoye and Bayanovskoye deposits (near Severouralsk ) and Olkhovskoe (near Krasnoturyinsk ) ^[2] . In 1770, Pokhodyashin launched the Theological Copper Smelter . In 1791, the sons of Pokhodyashin sold the plant and mines to the treasury. In July 1875, the treasury sold the Bogoslovsky mining district (mines and factories) to the state councilor Sergey Dmitrievich Bashmakov (03/12/1831—20.06.1877) for 2 million rubles, and his son Sergey Sergeevich Bashmakov sold the BGO Nadezhda Mikhailovna Polovtsova for 5 million rubles in 1884 , 5 million rubles ^[3] . In 1886, exploration was resumed at the Olkhovskoye (later Auerbakhovskoye) field under the direction of the BGO manager A. A. Auerbach . In 1894-1899, detailed topographic and geological surveys of 4 thousand square kilometers were conducted under the guidance of the Petersburg geologist E. S. Fedorov ^[2] . Since 1894, the Auerbakhovsky (Olkhovsky) iron mine became the main source of raw materials for the Nadezhda plant , located 21 versts. Red and brown iron ore containing from 50 to 60% iron with manganese (from 0.318 to 0.41%), phosphorus (0.045%), sulfur (0.07%) was mined at the mine. The deposit had magnetite and skarn, pyrite and chalcopyrite, and chromium-containing brown iron with iron in 44%. In 1894–1917, mainly martites, containing 61.3% of iron, and less brown iron ore were mined, and sulfur-containing magnetites (60.5% of iron, 0.81% of sulfur, 0.1% of phosphorus) were not taken. Ore was mined by the open method. All ores were found in clay rocks and needed to be enriched, washed ^[4] .

In the years 1900-1917

A railway line was connected to the Auerbach mine . In it, in 1895, 2.05 million poods of ore were mined, in 1900 - 4.95 million poods, in 1914 - 13.7 million poods. The cost of ore at the end of the XIX century. was 2.88 kopecks per pound, which was lower than in the Urals (3-3.5 kopeks), and at the beginning of the XX century. decreased to 1.5-2 kopecks The mine in 1900 was the third in the Urals, and in 1914 the second. In 1895, the number of mines amounted to 504 workers, in 1901 - 723 workers ^[4] . From August 1915, Chinese workers began to arrive at the mines in connection with the lifting of the ban on the use of foreign labor in 1914, and by November 1917 there were already 278 people on the Auerbach copies ^[5] .

At the beginning of the 20th century, mining took place at the Vorontsov mine , located 38 versts from the Nadezhdinsky plant, and magnetic iron ore was mined with a content of 58% iron. In 1911, 4.6 million poods of ore were mined. The Pokrovsky mine was developed with deposits of the stocks of magnetic iron ore with an iron content of 49–56%, and in 1914–18 it produced 3 million pounds per year. The Samskoye deposit was developed 80 versts from the Nadezhda plant, a deposit of brown iron ores with an iron content of 43%, pure in sulfur and phosphorus, but in clays it was necessary to wash. In 1915-1918, 1 million poods of ore were mined here per year. The mines of the North No. 1 and No. 2 with a large deposit of high quality magnetic iron ore with an iron content of 55-65%, located along the r. Tynie and r. Lozve, 190 and 300 versts north of the Nadezhda plant, were not developed due to the remoteness and lack of communication lines ^[4] .

In the years 1917-1940

After 1917 the Theological mines were nationalized, the work on them was almost stopped: in 1918, 46.2 thousand tons were mined, in 1919 - 5.2 thousand tons, in 1920 - 24 thousand tons. In 1929, the Theological Mine Administration was separated from the Nadezhda plant . Mining was carried out at the Auerbakhovsky, Vorontsovsky, Troitsky, Pokrovsky, Samsky mines, preparatory works were carried out at the Bayanovsky mine, and at the Talinsky and Langursky were designed for development. In 1931, ore mining reached 265 thousand tons and 902 workers were employed. Since 1936, began underground mining. In 1941, the mine “No. 6”, the washing facilities “No. 1” and “No. 2” operated at the Auerbakhovsky mine, the “Mineral” mine was built with the crushing and processing plant, and the Yuzhny and No. 4 mines worked at the Vorontsovsky mine. and the South-inclined mine. In 1940, 220 thousand tons of iron ore were mined ^[4] .

In the years 1941-1945

Production during the Great Patriotic War increased dramatically due to the launch of the old mines laid and the construction of new mines and mines: in 1942, 290 thousand tons were mined, in 1943 - 290 thousand tons, in 1945 - 446 thousand tons. raw ore. In December 1941, the Severnaya mine was launched at the Vorontsov mine. In 1943, the open-cut development of the Maslovsky magnetite and martite deposits began. In 1944, the Kapitalnaya mine was launched at the Auerbakhovsky mine, the Yuzhnaya mine at the Vorontsovsky mine, the mine-washing plant No. 4 for washing the old dumps of the Auerbach mine, the Pokrovsky mine resumed operation. In 1945, crushing and concentrating plants were launched at the Kapitalnaya mine and at the Pokrovsky mine ^[4] .

In the years 1946-1999

Since the 1970s, mining has been completely underground. In 1966, on the basis of the Peschanskoye deposit, the Severopeschanskaya mine was laid with a design capacity of 5 million tons of raw ore per year. The magnetite ore deposit with an ore body length of 3 km was opened by several cage, ventilation and skip-iron ore-lifting trunks. At the end of 1967, the first stage of the mine was commissioned for 500 thousand tons of raw ore, in December 1969 new capacities for 2.2 million tons were launched. In 1980, the mine produced 4538 thousand tons of raw ore, which was a record amount of iron ore production in the USSR. In the 1980s, the Kapitalnaya mine was developed and closed, in the 1990s, the Pervomayskaya mine ^[4] .

Since 1999

Bogoslovskoye Mineral Administration OJSC became part of the Ural Mining and Metallurgical Company in 1999. Currently, there is only one Severopopeschansky mine, and enriched ore with an iron content in raw ore from 34.6 to 36.3%, and in concentrate - 52.3% is sent to the Nadezhda plant. When the mine operates crushing and processing plant, designed by the research institute " Uralmekhanobr ", and enriching the ore mass by dry magnetic separation, after which the resulting iron ore concentrate enters the railway shop of the enterprise, where the shipment to the consumer occurs ^[4] .
