In 2011, Russia produced about 336.3 million tons of coal materials. This illustrates 4% growth over the 2010 total production, so 2011 became a record level year in coal production in Russia. 90% of the coal output was provided by just the 18 largest producers in the coal mining industry, demonstrating the concentrated nature of the Russian coal mining business.
Since the early 2000s Russia benefits the status of coal net-exporter. Russia became the world’s third coal exporterafter Australia and Indonesia – with about 11% in global coal trade. Prior to 2009 Russia’s coal export was oriented mainly EU – with 73.4% share. Coal mining industry developing requires advanced mining technology and high performance coal crushing plant and mining equipment.
Underground coal mining is one of the often used coal mining methods. Longwall mining and room-and-pillar mining are the two basic methods of mining coal underground.The choice of mining technique is site specificbut always based on economic considerations;differences even within a single mine can leadto both methods being used. Many different types of mining machinery involved in the mining operation.
When coal seams are near the surface, it may be economical to extract the coal using open cut or open pit mining methods. Strip mining is typically used for coal. Open cast coal mining recovers a greater proportion of the coal deposit than underground methods. Globally, about 40 percent of coal is produced by surface mining. Bachatsky open-pit coal mine is one of the largest mines of Kuzbas. Its annual output is over 8 million 700 thousand tons. It extracts fuel for energetic and metallurgical fields of Russia and many other countries of the world.
Russia is currently sixth in the world in terms of coal production. It produced 323 million tons of coal in 2009, roughly 4% of the world's total production. Coal production decreased in the 1990s with the fall of the Soviet Union, going from a production of 425 million tons in 1988 to 232 million tons in 1998. Production began to recover in 2003 and reached 329 million tons, although production has declined since then. The major areas of coal production are the Donets, Moscow, Pechora, Kuznetsk, Kansk-Achinsk, Irkutsk and South Yakutsk basins.
In coal mining operation, several technics will be involved including extraction, crushing, grinding, screening, washing, processing etc. Each stage requires different types of machines. SBM provides complete series of coal mining equipment in Russia, including extraction plant, crusher machine, pulverizer mill, vibrating screen, belt conveyor, coal washing plant, coal preparation machine etc. Please contact us for more information.
Coal crushing is the first stage in coal preparation operation. In the coal crushing plant production flow sheet, the raw material will be conveyed by belt conveyor into jaw crusher for primary crushing. The oversized material will be fed into the impact crusher and cone crusher for secondary and tertiary crushing. There is vibrating screen between each crushing process to sieving the different particle size.
SBM is world leading supplier and manufacturer of mobile crushing plant. SBM mobile coal crusher machine can be fitted with jaw crusher or impact crushers, with or without screens, and equipped with closed circuit and discharge conveyors as required. Capacities range from 150 to 2000 mph, which can be applied in large scale, medium scale and small scale crushing applications. We also customize track mounted mobile crushing solution according to specific requirements for coal mining plant. Please feel free to chat online with us for more information.
