It is known that coal is different.There are black and brown the variety, anthracite.The coal seams are located at different depths, and this determines the depth of mining methods.
layers at depths ranging from 100 to 150 meters of mined pit method.All processes in the extraction of coal from the mine are maintained on the surface.At a deeper-lying using underground mining.It is the most time-consuming method, but it allows us to develop the most powerful layers whose thickness can sometimes exceed 30 meters.
most cost-effective method of coal mining is considered open.About 70% of the Earth's coal reserves are developed in this way.Europe's largest (and some experts believe that in the world) is Korkinsky coal mine.It is located near the village of Rosa in the Chelyabinsk region.During its development it was used traditional technologies.
first spent stripping and overburden removed.Then, with the help of blasting began to extract coal.Korkinsky explosion penetrated the mine, went down in history.In 1936, it prepared the explosion were raised in the air more than a million cubic meters of earth.The release reached a height of 500 meters, and the explosion of several seismic stations have registered.The thickness of the layers found by geologists in 1932 exceeded 200 meters.
Korkinsky the cut is so large that it is located not only all the necessary machinery (excavators, bulldozers, railcars and 14 locomotives), but also a power substation, which provides electricity to the railway line.Today Korkino coal mine has a depth of over a mile and a diameter greater than 2.5 kilometers.Dumps of waste rocks surrounding it for many kilometers.Coal mining is conducted there from 1932 to the present day.And all the coal from the bottom of the quarry is transported using rail transport.
Korkinsky section of today - not only the largest field, but also a source of economic and social problems.The walls of its sides are so deep that in 2012 there was a real threat of collapse.Under the threat turned out to be the entire population of the village of Rosa, next to which is Korkinsky cut.
In connection with these events, field visits Russian Emergencies Minister Vladimir Puchkov.After seeing the field, he suggested that the Government of the Chelyabinsk region to consider a program of closing the quarry.In addition, at the initiative of the Minister it was taken emergency relocation of all residents of Roses.Only the first stage of a large-scale resettlement program cost the budget of the Chelyabinsk region in more than five billion rubles.
Naturally, the court's decision to stop the work has caused excitement among all those who work in the quarry.However, Vladimir Putin, who visited the mine in February 2013, assured the workers, saying that Korkinsky cut will function until an official project will be to eliminate it.Moreover, he offered to support the workers of the cut (over a thousand) of additional orders.After the departure of Vladimir Putin had signed agreements for the supply of coal mined in the context of a period of five years.
for successful completion of the relocation of the Chelyabinsk region was granted a federal cash transfer of two billion rubles.In order to protect residents and workers from the collapse of the walls, on the floor of the quarry from December 2012 started functioning seismic station.Its mission - to timely warn about the possible activity of the walls of the quarry.
There are several reclamation projects cut, but none of them has not been approved officially.It is assumed that the pit can be transmitted "Russian Copper Company" or the other side of the user, or turned into a decorative pond.
