Description
Turgoyaksky quarry is an enterprise specializing in the extraction of fluxing limestone, which is located in the Chelyabinsk region. Beginning in 1920, the Turgoyak mining department of the Uralruda trust began developing a deposit of fluxing limestone in order to obtain construction lime. Since 1930, limestone began to be mined as a high-quality flux raw material for the needs of the Zlatoust metallurgical plant of the Glavspetsstal trust.
Exploration of the deposit was carried out in the 1920s, and additional exploration of reserves - in 1933-34. The flux limestone layer ranges from 120 to 800 meters in width and extends 3 kilometers in a southwest direction. The limestones are partly marbled and occur among greenschist rocks, and are also interrupted by diabase dikes and calcite veins. The limestone here is distinguished by a high degree of purity, containing less than one percent of foreign impurities. Total reserves of raw materials are estimated at approximately 95 million tons.
Currently, the quarry is used by the Turgoyak Mining Administration as a source of flux raw materials for metallurgical enterprises in the Urals, while crushed stone and lime chips are also mined.
The deposit is surrounded by swamps on three sides, but the water permeability of the limestone is low. The influx of water into the quarry is carried out through the contact zones and along destroyed limestones, reaching 500-700 m³/hour. On July 19, 1944, the People's Commissar of Ferrous Metallurgy of the USSR I. Tevosyan issued an order on the formation of the Turgoyak Mining Administration in order to provide the Chelyabinsk Metallurgical Plant, as well as the metallurgical enterprises of Zlatoust, Bakal, Asha and Satka with fluxed limestone.
In the process of development of the enterprise, production volumes increased, modern technologies for that time were introduced, such as excavators and diesel locomotives. In 1972, the second factory was put into operation. In the 70s, cyclic-flow technology was introduced at the TRU quarry, and a new crushing and screening unit SDA-1000 was installed, which brought a significant economic effect.
The period from the 70s to the 80s is the time of the greatest prosperity of the enterprise, which repeatedly took first place in socialist competition among enterprises of the city, region and industry.
The Turgoyak quarry has become an object of interest for metallurgical enterprises not only in the Chelyabinsk region, but also in other regions of the country. Enterprises such as the Volzhsky Pipe Plant, Cherepovets Metallurgical and Kostomuksha Concentrating Plants became important consumers of the products. Until 1991, the Turgoyak quarry produced up to 4.5 million tons of fluxed limestone per year and was considered one of the largest mining enterprises in the country.
