Coal Underground Mining Equipment

May 18th, 2012

The majority of the world’ s fossil fuel reserves are retrieved though underground mining. Currently, almost two-thirds involving hard coal generation worldwide comes from underground mines, but in certain critical coal producing international locations, such as the U.Utes. and Australia, this proportion is significantly reduced.

Underground mines bring extracting coal tissue deeper than 100 to 200 feet. 7 Most undercover mi nes are less than 1000 feet underg spherical. However, some can easily reach depths up to 2000 feet. Eight Passageways and underground workrooms are dug to enable your mi ners and machines to succeed in the deposits. Equipment inside various pass agesinclude normal water pumps or other waterflow and drainage systems to remove seepage h2o. There are additional requirem ents that exist in subterranean mining that do not exist in surface mining. That they include: roof support, ventilation, lighting, water drainage, methane control, equipm ent gain access to, and coal conveyance, and others.

Technological success has changed the life of everyone in the world and it has also changed the way coal mining companies explore and market coal. High-tech and safe exploitation and usage of coal is the demand of the 21st century.

In order to correspond to these new requirements the effective organizing management of human resources must take place. In other words, the technologies have made a coal mining industry a high-technological affair that is equipped with computers and all the necessary machinery Nowadays thousands of men and women in the world are working in 2,560 mines in 26 countries to supply billions tons of coal. Till the 1950th coal mining companies applied two methods of explorationsurface mining techniques or underground ones. Surface mining techniques are popular and are widely used in the USA mines since 1970s. This method is useful when coal deposits lie near the surface and can be easily extracted. Another methodan underground oneis used when coal deposits lie deep under the surface. In this situation continuous mining machines are used in the room-and-pillar method.

In the 1950s, a new underground mining method appeared in Europe. Today, it is widely used by coal mining companies in the world. From this moment the coal exploration, extraction and delivery to the market have become secure, effective, clean and not harmful for the environment. Nowadays the use of computers, lasers, satellites and other technologies has become a usual thing in coal mining industry and many coal mining organizations, such as Globaltex Industries Inc, apply all these advances in their business. From now on the coal mining extraction has become absolutely safe for people thanks to high-tech technologies and effective human resources management work.

The high-tech mining technology is of great importance in enlarging the competitive forces of the coal mining industry. The state and private coal mining corporations make great efforts in order to put into action high-tech technologies, so that up-to-date equipment. The coal mining industry is becoming more and more mechanized.

Mission Description The United States Department of Commerce, International Trade Administration, U.S. and Foreign Commercial Service is organizing an Executive-led Trade Mission to China and Mongolia for U.S. companies operating in the coal and mining sector and manufacturing or distributing mining and mining-safety equipment. The trade mission, scheduled for October 23-28, 2011, will begin October 23 in Mongolia’s capital of Ulaanbaatar, followed October 25-28 by the China portion of the mission, which will visit two cities i’an and Beijing. The mission will include individual participant meetings tailored to each company’s goals as well as appropriate government meetings. The mission will conclude at the China Coal and Mining Expo taking place October 28-31, 2011 in Beijing. Commercial Setting China China is the United States’ second largest trading partner and the world’s second-largest economy. Last year, U.S. manufactured exports to China were close to $92 billion. Since 2000, U.S. exports to China have more than quintupled. The Chinese government has announced an annual growth target of 7 percent over the next five years, which is regarded as a conservative estimate. China is the largest coal producer in the world, with about 45% of the world’s total annual production. As energy demand increases for its rapid economic development, China’s coal production is growing yearly. For the past three years, the country’s coal production was 2.7 billion tons, 2.9 billion tons, and 3.2 billion tons respectively. It is expected to reach 4 billion tons in 2011. Coal currently accounts for between 65-70% of China’s primary energy supply, and demand for coal is forecast to grow 3.2% annually through 2030. About 90% of the coal mining equipment used in China is produced domestically. However, Chinese companies are still behind technologically in mining equipment production. China is also the world’s largest emitter of greenhouse gases (GHGs), responsible for over 20% of annual CO2 emissions from burning fossil fuels. Eighty percent of these emissions come from coal. Domestic scarcity of high- quality, cleaner-burning coal poses an additional challenge. While coal usage efficiency has improved in China, it remains low compared with developed countries. Power generation accounts for 48% of China’s coal consumption and a large proportion of flue gas remains untreated prior to emission. China welcomes foreign participation in the clean-coal sector, including improving the efficiency and clean use of coal. However, significant challenges remain, particularly industry fragmentation, which limits both the quality of the coal that is mined and the ability of coal companies to invest in newer, cleaner technologies. Stronger and more uniform application of standards and incentives is also needed. Mining U.S. companies enjoy their greatest competitive advantage in supplying heavy coal mining machines and systems. For underground mining operations, U.S. firms compete well in the following categories: long-wall shearers, stage-loaders, continuous miners, batch haulage vehicles, road headers, hydraulic roof support systems and conveyor systems. For open-pit mining, U.S. firms’ best opportunities include electric mining shovels, walking draglines, blast hole drills, and heavy mining trucks. Coal Mine Safety Coal mine safety remains a critical issue in China. In 2007, China saw 3,786 deaths in coal mine accidents. In order to address the issue of safety, the Chinese government closed 2,969 small coal mines (below 30,000 tons of production capacity) considered unsafe. The Chinese government requires all coal mine sites to install a complete safety system, which includes a monitoring system, life shelters, communications system, personnel positioning system, and ventilation and water system. According to the State Administration of Coal Mine Safety Supervision, China is aggressively purchasing safety equipment for large state-owned coal mines. China will spend billions of dollars over the next five years to improve safety in its 10,000-plus coal mines. Many analysts predict that China will need to invest over $151 billion in coal infrastructure by 2020. Part of this investment will cover improvements for coal mine safety. This creates significant opportunities for foreign companies to export coal- mine safety equipment to China. Best prospects also include gas control systems and fire and gas monitoring and control equipment. The industry will see continued consolidation and a push toward bigger, safer and more modern mines. This is part of the overall policy goal of increasing efficiency, safety and reducing waste. Clean Coal Clean coal solutions can be divided into three categories based upon the stage of energy production: pre- combustion, conversion and combustion, and post-combustion. U.S. suppliers enjoy good prospects in all three categories. Pre-combustion: advanced and energy efficient coal-mining equipment, coal blending, coal screening and scrubbing. Conversion and combustion: coal liquefaction, gas-turbine technology, Integrated Gasification Combined Cycle (IGCC), Ultra Supercritical Power Generation (USPG), Underground Coal Gasification Combined Cycle (UCGCC). Post-combustion: Carbon Capture and Sequestration (CCS), Flue Gas Denitration (De-NOx), Flue Gas Desulphurization (De-SOx), Particulate Matter (PM) removal. Mongolia Mongolia is a vast country with rich natural resources, including coal, copper, molybdenum, tin, tungsten, and gold, making mining the most important sector for Mongolia’s economic development. Its world-class mineral deposits have attracted considerable investment in recent years over $600 million in direct foreign investment in 2010. The landmark Oyu Tolgoi Copper- Gold Mining Project Investment Agreement signed in 2009 between the Mongolian government, Ivanhoe Mines and Rio Tinto has so far brought over $2 billion into Mongolia. Mining is crucial to Mongolia’s development and the mining sector has been a major contributor to the country’s GDP. Once major mining projects go into production, Mongolia should see a significant increase in GDP growth, estimated at over 13% for 2011- 12. This development undoubtedly will be accompanied by a surge in mining- related imports of plant and machinery. Furthermore, the expansion of the mining sector will have a far-reaching effect on other sectors.

 

Mining Industrial News : Shanxi to become reform trial zone for resource-based economy

December 22nd, 2010

The State Council has given its approval for China’s coal-rich Shanxi province to become a reform trial zone so as to change its over-dependence on resources exploitation, Xinhua News Agency reported on Dec 14.

This means that the province will become one of the nine trial zones that the country has established, and it is the first trial area that will cover an entire province.

Peng Sen, Vice Minister of the National Development and Reform Commission (NDRC), said at a press conference on Dec 13 that the goal of the zone is to transform the conventional industries and strike a balance among the agricultural, industrial and tertiary sectors in Shanxi.

He also said that this part of the province’s reform is significantly different from previous initiatives, as it is closely related to production, and that “good experiences and practices have been learned from other trial zones and will be given priority when initiatives are considered for implementation in Shanxi.”

According to the report, the annual coal production of Shanxi was 10 million tonnes over the past 60 years, 75 percent of which was transported to regions all over the country. In addition, the industrial structure of Shanxi – with the four sectors of coal, hard coke, metallurgy and electricity – make up 80 percent of the total value of its gross output.

Lin Boqiang, the director of the China Center for Energy Economics Research at Xiamen University, told the Global Times that such an industrial structure relies heavily on the market outside the province.

“If the international or national economy encounters some development problems, the entire economic growth of Shanxi also gets into trouble.” Lin said.

Niu Renliang, Vice Governor of Shanxi, said that the province has retained an unsustainable industrial structure, adding that Shanxi has powered the economic development of other regions, but with heavy economic, social and environmental consequences for itself.

The coal-based economy had not brought prosperity to the people of Shanxi Province, according to the Beijing News’ report, and residents have not benefited from the mining exploitation economy. The urban per capita disposable income and rural net income rank in the last 10 among China’s 31 provincial-level areas.

For every tonne of coal extracted in the province, 2.48 tonnes of water is polluted, and coal mining has resulted in 20,000 square kilometers of land at risk of subsidence, accounting for one eighth of the province’s total area.

The energy consumption and sulfur dioxide emission in Shanxi is twice that of the national level, the report said.
