Neryungri coal mine. Neryungri coal deposit
On the territory of the Neryungri region of the Republic of Sakha (Yakutia).
There are about 20 layers in the composition of the Neryungri field. Most of them come to the surface, which makes it possible to mine coal in the open major quarries. The most coal-bearing suite containing the "Powerful" layer at the Neryungri deposit. This is a trough deposit with an area of 16 km 2 with a maximum depth of 320 meters in the central part of the trough. The average thickness of the reservoir is 26.5 meters, the maximum is up to 120 meters.
The license for the development of the Neryungri deposit belongs to AO HK Yakutugol. The design capacity of the Neryungri coal mine is 13 million tons per year. The mining development program is designed up to 2034.
Field development
In 1951, while surveying G. Yu. Lagzdina, the Five-meter layer of the Neryungri deposit was discovered, which was the beginning of the industrial development of the South Yakut coal basin. In the same year, in accordance with the Government decision to accelerate the prospecting and exploration of coal and iron ore deposits in the south of Yakutia, the South Yakut Complex Expedition (YYACE) was founded, whose efforts proved the high potential of the Neryungri coal deposit. S. S. Karimova made a great contribution to the geological study of the South Yakutsk coking coal basin. It was under her leadership that the completion of the exploration of the Neryungri coal deposit was carried out.
The construction of the Neryungrinsky open pit was carried out in five separate phases. On February 23, 1976, the symbolic first bucket of rock was lifted in the excavator driver V. Vinshu at the construction site of a new “large” open pit, and on March 19, 1979, an order was signed to put the first stage of the open pit construction into operation. This date is considered the official birthday of the enterprise. Conducted coal samples showed that almost half of the deposits are coking coal. The section gradually gained capacity, and on July 16, 1983, one hundred million cubic meters of overburden was lifted.
Brief geological description
The Neryungri coal deposit is located in the Aldan-Chulmansky coal-bearing region of the South Yakutsk coal basin. The climate of the region is sharply continental, the duration of the period of the year with positive temperatures is 137 days, and with negative temperatures - 228 days. The height above sea level in the area of the deposit ranges from 600 to 1200 meters. The deposit is a closed brachysyncline fold (6×3.9 km), elongated in the direction from northwest to southeast. Among the lithological varieties in the section of the Neryungri Formation, various sandstones from fine to coarse-grained prevail, making up to 80-82% of the section. Fine-grained rocks - siltstones and mudstones make up about 11% of the section.

OAO HC Yakutugol is one of the largest coal mining enterprises of OAO Mechel Mining. The company includes four mining enterprises: the Neryungrinsky open pit, the Elginsky open pit, the Kangalassky open pit, the Dzhebariki-Khaya mine, and the Neryungrinskaya processing plant. In this report, you can see how coal is mined and enriched at the largest deposit"Neryungri".
OAO HK Yakutugol is one of the few producers of hard coking coals in Russia. This is mainly high-quality coal of the valuable K9 grade. Yakutugol's products are in great demand both on the domestic and foreign markets. Coking coal concentrate is supplied to metallurgical and coking enterprises in the central regions of Russia, exported to the countries of the Asia-Pacific region, Ukraine. Deliveries of thermal coals to the domestic market are carried out to energy, cement and housing and communal enterprises of the Far Eastern Federal District of Russia.
Let's go down to the quarry. As I wrote in the post below, during the days of my business trip, it snowed in the city of Neryungri, but this did not prevent the company from slowing down work, and the picture turned out to be very interesting.
The total coal reserves at the Neryungrinsky open pit are about 200 million tons.
To implement the technical re-equipment plan, the company attracted foreign investment. According to the technical re-equipment plan, two powerful Komatsu PC-8000 excavators with a bucket capacity of 36 cubic meters were received. m, 25 heavy vehicles and other equipment.
This is how a tow truck for BELAZ looks like.

The mined coal is processed at the Neryungrinskaya enrichment plant, which has an annual capacity of 9 million tons.
The Neryungrinsky open pit has a railway connection with the Baikal-Amur and Trans-Siberian mainlines, through which finished products are delivered to Russian market and for export.
Among all Russian manufacturers Coking Coal OAO Holding Company Yakutugol is located closest to the Far Eastern ports, through which the main coal supplies to Asian countries characterized by rapidly growing economies are carried out.

The share of bituminous coals accounts for about 6%, gravelstones and conglomerates 1-2% of the stratigraphic section. Quaternary deposits in the field are ubiquitous. They are represented by sands and pebbles. Their thickness ranges from 1-3m. The formation dip angles are variable: on the northeastern flank they are 15-20 degrees, on the north-western and south-eastern flanks they are less than 10-12 degrees.
The qualitative characteristics of the coals of the Neryungri deposit are presented in the table.
