Bitcoin is a digital asset and a payment system invented by Satoshi Nakamoto, who published the invention in 2008 and released it as open-source software in 2009. The system is peer-to-peer; users can transact directly without an intermediary. Transactions are verified by network nodes and recorded in a public distributed ledger called the block chain. The ledger uses bitcoin as its unit of account. The system works without a central repository or single administrator, which has led the U.S. Treasury to categorize bitcoin as a decentralized virtual currency. Bitcoin is often called the first cryptocurrency, although prior systems existed. Bitcoin is more correctly described as the first decentralized digital currency. It is the largest of its kind in terms of total market value.
Bitcoins are created as a reward for payment processing work in which users offer their computing power to verify and record payments into a public ledger. This activity is called mining and miners are rewarded with transaction fees and newly created bitcoins. Besides being obtained by mining, bitcoins can be exchanged for other currencies, products, and services. Users can send and receive bitcoins for an optional transaction fee.
The goal of coal mining is to obtain coal from the ground. Coal is valued for its energy content, and, since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United States, United Kingdom, and South Africa, a coal mine and its structures are a colliery. In Australia, "colliery" generally refers to an underground coal mine.
Coal mining has had many developments over the recent years, from the early days of men tunneling, digging and manually extracting the coal on carts, to large open cut and long wall mines. Mining at this scale requires the use of draglines, trucks, conveyors, jacks and shearers.
Small scale mining of surface deposits dates back thousands of years. For example, in Roman Britain, the Romans were exploiting all major coalfields (save those of North and South Staffordshire) by the late 2nd century AD. While much of its use remained local, a lively trade developed along the North Sea coast supplying coal to Yorkshire and London.

Uranium Resources' Mark Pelizza explains how uranium is mined--either through a conventional or in situ uranium mining process--to provide fuel for U.S. nuclear energy facilities. He also discusses where the uranium comes from that is used to power U.S. nuclear plants. For more information on uranium mining, see NEI's website: http://www.nei.org/howitworks/nuclearpowerplantfuel/.
Joy Mining Machinery releases a new version of its most popular video "Pioneering Underground Mining". You can request a free copy of this video by contacting webresponse@joy.com and provide your name and mailing address and if you want the copy in DVD or Blu-ray format. It was first produced in 2001 to support a request by our US Midwest sales region to help a customer explain the difference between room and pillar and longwall mining to finance people. It quickly became the most widely distributed video in our library being used by universities, schools, shown to community groups, etc. The program was updated to show new products and includes all new HD video and animations.

Diamond Mining - How are diamonds mined and formed? Documentary Film In mineralogy, diamond is a metastable allotrope of carbon, where the carbon atoms are organized in a variation of the face-centered cubic crystal structure called a diamond lattice. Ruby is less secure than graphite, yet the conversion rate from ruby to graphite is negligible at typical problems. Diamond is renowned as a material with outstanding physical high qualities, the majority of which stem from the strong covalent bonding between its atoms. Specifically, ruby has the highest solidity and thermal conductivity of any type of mass material. Those properties figure out the major industrial application of diamond in cutting and polishing tools and the scientific applications in diamond blades and ruby anvil cells. A...
Ghana has had a gold rush but here, Afua Hirsch discovers how Chinese immigrants are profiting from industrialising the country's small-scale mining industry.
