Shibanxi Railway
The Jiayang Coal Railway, also known as Shixi–Huangcunjing Railway or Shibanxi Railway, is a narrow gauge railway in Sichuan in Qianwei County near Leshan, China. History A coal mine was established at Bajiaogou (芭蕉沟) in 1938. The coal was initially transported in manually-propelled trucks on a gauge railway track to Mamio, where the coal was loaded onto barges on the Mabian river. Two SJ380A diesel engines with numbers 01 and 02 were purchased and commissioned in 1991. They were already taken out of use in 1996. For the electrified part of the line between Shixi and Yuejin three ZL 14-7 electrical locomotives with four wheels each were purchased in the year 2000. Coal was initially transported in waggons with a bamboo superstructure, and later with a wooden superstructure. Today, two-axle steel waggons are being used. For the passenger service, two-axle carriages with open windows are used, and for checked-in luggage there are four-axle carriages available. The t ...

Zig Zag (railway)
A railway zig zag or switchback, is a method of climbing steep gradients with minimal need for tunnels and heavy earthworks. For a short distance (corresponding to the middle leg of the letter "Z"), the direction of travel is reversed, before the original direction is resumed. Some switchbacks do not come in pairs, and the train may then need to travel backwards for a considerable distance. A location on railways constructed by using a zig-zag alignment at which trains must reverse direction to continue is a reversing station. One of the best examples is the Darjeeling Himalayan Railway, a UNESCO World Heritage Site railway in India, that has six full zig zags and three spirals. Advantages Zig zags tend to be cheaper to construct because the grades required are discontinuous. Civil engineers can generally find a series of shorter segments going back and forth up the side of a hill more easily and with less grading than they can a continuous grade, which must contend wi ...

Mining Railways
A mine railway (or mine railroad, U.S.), sometimes pit railway, is a railway constructed to carry materials and workers in and out of a mine. Materials transported typically include ore, coal and overburden (also called variously spoils, waste, slack, culm, and tilings; all meaning waste rock). It is little remembered, but the mix of heavy and bulky materials which had to be hauled into and out of mines gave rise to the first several generations of railways, at first made of wooden rails, but eventually adding protective iron, steam locomotion by fixed engines and the earliest commercial steam locomotives, all in and around the works around mines. History Mine rails Wagonways (or tramways) were developed in Germany in the 1550s to facilitate the transport of ore tubs to and from mines, using primitive wooden rails. Such an operation was illustrated in 1556 by Georgius Agricola of Germany (Image right). This used "Hund" carts with unflanged wheels running on wooden planks an ...

Coal In China
China is the largest producer and consumer of coal in the world. It is also the largest user of coal-generated electricity, with over a thousand coal-fired power stations. The share of coal in the energy mix declined during the 2010s, falling from 80% in 2010 to 58% in 2019. China emits over 10% of global greenhouse gas. China's large demand was in part responsible for the delay in peak global coal production, coal production reached a record high in December 2021 and coal consumption in China is forecast to reach a record high in 2021. Overall electricity consumption continued to rise in the 2010s, and new coal-fired power plants were constructed to help meet demand. But to curtail the pace of coal-fired power station construction, the National Energy Administration in 2017 canceled coal-fired power plant permits that would have amounted to 120 GW of future capacity. However, local authorities seeking to create jobs resisted the efforts of central authorities to cut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chinese Yuan
The renminbi (; symbol: ¥; ISO code: CNY; abbreviation: RMB) is the official currency of the People's Republic of China and one of the world's most traded currencies, ranking as the fifth most traded currency in the world as of April 2022. The yuan ( or ) is the basic unit of the renminbi, but the word is also used to refer to the Chinese currency generally, especially in international contexts. One yuan is divided into 10 jiao (), and the jiao is further subdivided into 10 fen (). The renminbi is issued by the People's Bank of China, the monetary authority of China. Valuation Until 2005, the value of the renminbi was pegged to the US dollar. As China pursued its transition from central planning to a market economy and increased its participation in foreign trade, the renminbi was devalued to increase the competitiveness of Chinese industry. It has previously been claimed that the renminbi's official exchange rate was undervalued by as much as 37.5% against its pur ...

Direct Current
Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alternating current via an inverter. Direct current has many uses, from the charging of batteries to large power sup ...
