Pechora Coal Basin
The Pechora coal basin (Печорский угольный бассейн) is located in the Extreme North of European Russia. In covers nearly 90,000 km2 in Komi Republic and Nenets Autonomous Okrug of the Arkhangelsk Oblast. The basin is associated with three major depressions: Usa River depression, Korotaikha depression and Kara depression, stretching North-South along the Western foothills of Northern Ural Mountains and Pay-Khoy Ridge. Coals in the basin widely range from brown coals to anthracite Anthracite, also known as hard coal, and black coal, is a hard, compact variety of coal that has a submetallic luster. It has the highest carbon content, the fewest impurities, and the highest energy density of all types of coal and is the hig ...s, of varying yield and ash content.

Komi Republic
The Komi Republic (russian: Республика Коми; kv, Коми Республика), sometimes simply referred to as Komi, is a republic of Russia located in Eastern Europe. Its capital is the city of Syktyvkar. The population of the republic as of the 2010 Census was 901,189.

The Komi territories came under the influence of Muscovy in the late Middle Ages (late 15th to early 16th centuries). The site of Syktyvkar, settled from the 16th century, was known as Sysolskoye (Сысольскoe).

CRC Press
The CRC Press, LLC is an American publishing group that specializes in producing technical books. Many of their books relate to engineering, science and mathematics. Their scope also includes books on business, forensics and information technology. CRC Press is now a division of Taylor & Francis, itself a subsidiary of Informa. History The CRC Press was founded as the Chemical Rubber Company (CRC) in 1903 by brothers Arthur, Leo and Emanuel Friedman in Cleveland, Ohio, based on an earlier enterprise by Arthur, who had begun selling rubber laboratory aprons in 1900. The company gradually expanded to include sales of laboratory equipment to chemists. In 1913 the CRC offered a short (116-page) manual called the ''Rubber Handbook'' as an incentive for any purchase of a dozen aprons. Since then the ''Rubber Handbook'' has evolved into the CRC's flagship book, the ''CRC Handbook of Chemistry and Physics''. In 1964, Chemical Rubber decided to focus on its publishing ventures ...

Usa River (Komi Republic)
The Usa (russian: Уса́; kv, Усва, ''Usva'') is a river in the northeast corner of European Russia that drains the Polar Urals southwest into the Pechora. The Polar Urals tend to the northeast and the Usa runs parallel to them. It is in the Komi Republic of Russia and the largest tributary of the Pechora, which it joins from the right. It is long, with a drainage basin of . The Usa has an average discharge of , but this varies from a maximum of in June to a minimum of in April. History The Usa valley has been inhabited for 40,000 years, as evidenced by the archaeological site Mamontovaya Kurya (Russian: Мамонтовой Курьи, "the mammoth curve"). With the Russian conquest of Siberia it became one of the main routes into Siberia. The route ran from the Pechora, which connects to other rivers in northern Russia, up the Usa, across the low Kamen Portage and down the Sob River to Ob River where there were customhouses at the Sob barrier and Obdorsk.

Brown Coal
Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat. It has a carbon content around 25–35%, and is considered the lowest rank of coal due to its relatively low heat content. When removed from the ground, it contains a very high amount of moisture which partially explains its low carbon content. Lignite is mined all around the world and is used almost exclusively as a fuel for steam-electric power generation. The combustion of lignite produces less heat for the amount of carbon dioxide and sulfur released than other ranks of coal. As a result, environmental advocates have characterized lignite as the most harmful coal to human health. Depending on the source, various toxic heavy metals, including naturally occurring radioactive materials may be present in lignite which are left over in the coal fly ash produced from its combustion, further increasing health risks.
