• Nazarovsky coal mine. There could shoot "Mad Max"
Nazarovsky coal mine located in the Krasnoyarsk region and is part of "SUEK-Krasnoyarsk". The main consumer of cut is Nazarovo GRES. In the 1970s Nazarovsky incision became a proving ground for the development of advanced coal technologies. It employs a unique set of rotary SRs (K) -4000 manufactured by German firm TAKRAF - the largest and most productive overburden complex in Russia.
Nazarovsky cut was put into operation in 1951. In the 1980s, when the brown coal needs were highest, production at the plant reached 14 million tons of coal per year. Now the production volume of the company is about 4 million tons.
The complexity Nazarovsky section is a large volume of rock, which are hidden under the coal seams. To get to the coal, it is necessary to extract up to 70 meters of soil. four types of stripping now working - rail, road, Conveyor and non-transport.
Railway overburden produced excavator EKG-10 dumpkarnuyu turntable.
dump cars - a car dumper with tilting and flaps for bulk material.
Clearing dump cars from adhering breed.
The main stripping ledge height and 35 m is fulfilled rotary excavator SRs (k) -4000 using a spreader. SRs (K) -4000 is a key link in the stripping activity Nazarovsky incision technology and operates about 60% of the overburden.
The conveyor working principle allows open rock bucket wheel, and then move the tape in the dump.
The height of digging - 36 meters, which is comparable with the height of 12-storey building.
The length of the rotor boom - 42 m.
Rotary wheel overburden complex. Wheel diameter - 16 meters!
On the wheel are mounted bucket 24 - 12 and the chain 12 Scoring, of 2,000 and 1,600 liters respectively.
This "giant mountain" is unique because it is the only one in our country.
During the year the SRs (k) consumes 7.93 million kW / h.
the complex Title SRs (K) -4000 excavator stands for (S) caterpillar (R) pivot (S) of execution of cold (K) capacity of 4000 cubic meters per hour.
The total weight of the complex is 9800 tons. It weighs as much as the Eiffel Tower in Paris.
The maximum construction height - 48 meters (16-storey house).
the complex movement speed - 2.6 m / min. The length of one track - 13 meters, width - 4 meters.
A total of Nazarovo section employs about 900 people.
The instrument panel.
stacker boom length - 195 meters.
During his tenure at the company SRs (K) -4000 moved to stockpiles over 150 million tonnes of overburden.
In winter, the complex does not work because of balling on the conveyor belts and the working body.
Once passed complex SRs (K) -4000, the remaining lower stripping ledge up to 20 meters in height is fulfilled draglines.
In the context of six Nazarovo draglines involved: two ESH20 / 90-2, one Esh15 / 90-1 and three Esh10 / 70-3.
Walking excavator ESH20 / 90.
The stationary excavator state rests on a ground support plate in the base; if necessary, make a "pitch" the weight is transferred to the support shoes. The excavator is lifted above the ground, is displaced by a certain distance and then sits on the bottom support plate. The support shoes, in turn, lifted above the ground and transported forward; then the cycle repeats.
The actual moving speed of 60-80 meters per hour, the maximum nameplate - 200 m / h.
The driver of the excavator.
The boom length of 90 meters.
Bucket capacity 20 m3.
But this is not the biggest excavator. Nazarovo section earlier worked legendary ES 100/100 (bucket capacity of 100 cubic meters) - the largest in Eurasia walking excavator and one of the world's largest mobile land rigs. In the 1990s, EL 100/100 excavator cut into scrap metal. Over the lifetime of EL 100/100 pereekskaviroval 121 million cubic meters of rock.
And then we got to the coal!
Its recess made rotary excavating ER-1250, output of 2,300 tons of coal per hour. During the years of operation of the excavator has shipped about 23 million tons of coal.
In a rotary wheel 18 buckets, each volume - 350 l.
excavator height - 22, 5 meters.
coal is transported by locomotives in the station "Coal-2" and further to Nazarovsky TPP. It consumes more than 95% of coal and therefore the cut extract as much coal as desired station. The rest of the coal taken out by self in the boiler and for local consumption.
All repair work on the section performs Nazarovo Mining and installation and commissioning management.
In 2013, the incision got jubilee 450 millionth tonne of coal since the beginning of exploitation of the deposit.
During the first 9 months of 2015 it was produced of 2, 5 million tons of coal.
Industrial stocks Nazarovsky cut - 210 million tons.
