Mine "Osinnikovskaya" is located within the city of Osinniki (Kemerovo region), in relative proximity to the city of Novokuznetsk. The distance to Novokuznetsk is 25 km. Between the cities there is a road and rail connection. The district center is the city of Novokuznetsk. Railway communication is provided by the Novokuznetsk - Tashtagol railway line. Mine is a leading enterprise in Osinniki.
Natural conditions
The climate of the region is characterized by high continental, long and cold winters. Summer is short and hot. Winter frosts can reach values of 45-50 degrees below zero. The snow thickness reaches 40-60 cm. The depth of soil freezing usually does not exceed 2 m. The total rainfall is about 500 mm per year. The winds of southern and southwestern exposure prevail.
The region is seismically unstable. The maximum possible strength of earthquakes is estimated at 7 points on the Richter scale.
History of the Osinnikovskaya mine
The year of foundation of the mine is 1932. From 1959 to 1975 the mine was enlarged and merged with Kuzbass and No. 4.
Now the mine is an open joint stock company. The year of its foundation is 1998. The mine is located at: Osinniki, Kemerovo region, st. Shakhtova, d. 3. It is part of the company Yuzhkuzbassugol.
In 1998, the total length of the coal mining zone at the Osinnikovskaya mine was 127 km. The mine had 10 shafts of ventilation. In the mining zone were located from 5 to 6 coal seams. The upper coal horizons are mostly already developed. The remaining reserves at a depth of 160 m are about 40 million tons. To a depth of 360 m, the recoverable coal reserves reach 248 million tons.
Since 1997, the reconstruction of the mine. A total of 39 billion rubles was allocated for these purposes. This is due to the need to replace obsolete and less efficient equipment with new, improved.
The current state of the mine
The mine is producing coal related to the layers of the Elban and Kandalep formations of the Kuzbass. The total area of production is 56.7 square meters. km, dimensions - 12 to 15 km. All production is conditionally divided into four blocks. The first and second blocks make up the central part, which is located in the active development zone. The third block refers to the western part, which is not being developed. The layers here have an inclined orientation. The fourth block is the north-eastern part, remote from the center, with a limited volume of workings. The fifth block is the northern part, the farthest from the center, which is not being developed.
At a depth of 160 m, the main stored coal reserves belong only to block 5. Therefore, the extraction in the most accessible blocks 1 and 2 requires the opening of deeper and undeveloped coal seams. The project involves the start of coal mining at a depth of 360 m. The reserves of the recoverable resource there are up to 30,000 tons. Taking into account deeper horizons (up to a depth of 600 m), the total reserves of coal available for mining are 250,000 tons.
Accident at the Osinnikovskaya mine
A serious accident happened at the mine in March 2013. This happened during preventive work on pumping water from flooded areas. At the same time, the collapse of a ten-meter pillar was recorded, which led to a breakthrough of water into the area of the workings. The collapse at the Osinnikovskaya mine was reported by the mine administration. Of the 143 miners working at the mine at that time, 139 were able to independently leave the mine. At the same time, three of them had minor injuries. Of the remaining four, one is listed as dead. The fate of the other three miners is not reported. It is only known that they worked on an intermediate drainage system.
In accordance with the decree of the governor of the Kemerovo region Aman Tuleyev, a working commission was created to assist victims of the collapse at the Osinnikovskaya mine and to eliminate the consequences of this emergency. In the accident zone, 5 rescue teams worked. Two medical teams were nearby in constant readiness.
The investigation of the emergency at the Osinnikovskaya mine was conducted by the Siberian branch of Rostekhnadzor. Perhaps the emergence of the accident contributed to the gigantic size of the mine and its long life. The most common causes of serious accidents in coal mines are methane explosions. Therefore, as a preventive measure, it is necessary to create a system for continuous monitoring of methane content in the air and early warning systems for timely notification of miners about an increase in the concentration of this gas.
