The scale mines and the cameras capture the imagination. Opened in 1929, the Novomoskovsk deposit of gypsum is considered the largest in Europe, and according to some estimates, and in the world. On the question whether it is possible to compare the amount of mining, with the volume of the Moscow metro, company employees smile: the magnitude of these underground facilities are simply incomparable.
Our journey with Ilya Varlamov begins with the inconspicuous entrance to the mine to the mill.
Before the descent we were given a protective suit, helmet and boots. As it turned out, for good reason :)
also each received an individual lamp and so-called "self-rescuer" -kislorodnoe device you want to use in an emergency.
The descent of 130 meters under the ground. Extracted breeds - gypsum - a 11-timetrovy layer at this depth.
Only five barrels arranged in the mine. They serve for the descent into the shaft of people and equipment, ventilation and recovery of mined raw materials. Some of them are not in use today.
The first barrel was built in 1947. Transportation trolleys breed only carried out in those years. The next stage of evolution - diesel vehicles. Now go through the mine dump, and extracted raw materials fed to the top special conveyor belt which is arranged in "buckets". The tracks are now only carry the explosives in the underground warehouse.
The total length of underground tunnels of more than 500 km! It's like from Moscow to the border with Ukraine. Without an underground vehicle fleet can not do accurately.
Each chamber is greater than the volume of the metro stations in two or three times. If you compare the amount of mining with the underground, then just all subways CIS combined.
Major highways are illuminated.
Due to the strength of the rock mined, there is no need to lay mines in the tubing or somehow strengthen the tunnel vaults.
The whole process looks like this:
- drilling the face of special drilling equipment, - loading otburennyh holes with explosives - blasting faces, - ventilation after blasting - loading of gypsum stone in dump trucks and delivery to the complex crushing - crushing, - the rise of crushed stone to the surface, - loading products in the rail cars or transportation to production through a combination of conveyor galleries.
Gypsum stone is quite strong and it can not produce the usual excavation equipment. To do this, at the bottom of wells are drilled and charged with explosives, which are produced directly at the plant.
According to the center of the chamber drilled six large wells that are not charged, and pose compensation surface to facilitate the work of the explosion.
In the year 2000 was completely eliminated manual labor drillers.

Remote Control installation.
Drilling of vertical holes.
After the explosion in the faces mining dust settles, blasters will check the presence of quiescent charges and then starts loading of gypsum in the dump.
On the work truck, crushing plant and underground pipelines - about how the mined gypsum is ground and deliver to the surface.
10 meter dump weight carrying capacity of 30 tons and 37 tons of gypsum delivery is carried to the subterranean complex crushing.
repair of all equipment is also carried out under the ground.
I wonder how many of the world's avtosersisov located at a depth of 130 meters?
Unloading dump on the scraper conveyor crusher.
Two mills with total capacity of 900 tons of stone per hour.
control over the conduct of the process of the underground crushing complex.
And this is a reversible conveyor shtrekovogo bunker.
Novomoskovsk mine gives a third of the gypsum produced in mines Knauf CIS.
An underground technological complex. Annually miners produce about 2, 5 million tons of stone.
Now mining complex in Novomoskovsk is a most perfect gypsum mine in the world.
An underground pipeline.
Then the raw material supplied to the complex secondary crushing.
Then the surface of the vertical conveyor system for delivery of crushed gypsum. System performance is 900 tons of stone per hour, or 6,480 tons per shift.
In 2000, excavation work was completed a new mine shaft with a diameter of 8 meters. In such a barrel, having no analogues in Russia, it was possible to lower the underground large equipment, which previously had to be disassembled and even cut into pieces, and then collect under the ground. By 2009 there was established the cage carrying capacity up to 40 tons. Now through this trunk is lowered into the mine equipment and machinery.

The industrial enterprise in Novomoskovsk was among the first purchased by an international group Knauf in Russia. Investor decided to modernize the mining complex and build on the site of production of modern building materials.
