Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an orebody, lode, vein, seam, reef or placer deposits. These deposits form a mineralized package that is of economic interest to the miner.
Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain any material that cannot be grown through agricultural processes, or created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water.
Mining of stones and metal has been a human activity since pre-historic times. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final reclamation of the land after the mine is closed.
Mining operations usually create a negative environmental impact, both during the mining activity and after the mine has closed. Hence, most of the world’s nations have passed regulations to decrease the impact. Work safety has long been a concern as well, and modern practices have significantly improved safety in mines.
Levels of metals recycling are generally low. Unless future end-of-life recycling rates are stepped up, some rare metals may become unavailable for use in a variety of consumer products. Due to the low recycling rates, some landfills now contain higher concentrations of metal than mines themselves.

Bitcoin is a cryptocurrency and worldwide repayment system. It’s the first decentralized digital money, as the machine works with out a central lender or sole administrator. The network is peer-to-peer and ventures happen between users immediately, lacking any intermediary. These trades are confirmed by network nodes by using cryptography and registered in a open public sent out ledger called a blockchain. Bitcoin was developed by an undiscovered person or group of folks under the name Satoshi Nakamoto and released as open-source software in ’09 2009.
Bitcoins are manufactured as an incentive for an activity known as mining. They could be exchanged for other currencies, products, and services. By Feb 2015, over 100,000 stores and distributors accepted bitcoin as repayment. Research made by the College or university of Cambridge quotes that in 2017, there are 2.9 to 5.8 million unique users by using a cryptocurrency wallet, almost all of them using bitcoin.

The Bodoland Territorial Council (BTC) is a territorial council in Assam state of India which have jurisdictions in Bodoland Territorial Area Districts. It was established according to the Memorandum of Settlement of 10 February 2003. BTC came into existence immediately after surrender of Bodo Liberation Tigers Force (BLTF) cadres. The BLTF laid down their weapons on 6 December 2003 under the leadership of Hagrama Mohilary and Hagrama was sworn in as the Chief Executive Member (CEM) on 7 December 2003. The BTC has 46 executive members each looking after a specific area of control called somisthi. The area under the BTC jurisdiction is officially called the Bodoland Territorial Area Districts (BTAD). The region falls within the geographical map of least developed region in India. The agro-based economy is the only source of livelihood of the people. Industrialisation and other employment opportunities are scant.
The BTAD consists of four contiguous districts — Kokrajhar, Baksa, Udalguri and Chirang — carved out of seven existing districts — Kokrajhar, Bongaigaon, Barpeta, Nalbari, Kamrup, Darrang and Sonitpur — an area of 8,822 km² (35% of Assam). It’s establishment was under the sixth schedule of the Constitution of India.

Mining engineering is an engineering discipline that applies science and technology to the extraction of minerals from the earth. Mining engineering is associated with many other disciplines, such as geology, mineral processing and metallurgy, geotechnical engineering and surveying. A mining engineer may manage any phase of mining operations – from exploration and discovery of the mineral resource, through feasibility study, mine design, development of plans, production and operations to mine closure.
With the process of Mineral extraction, some amount of waste and uneconomic material are generated which are the primary source of pollution in the vicinity of mines. Mining activities by their nature cause a disturbance of the natural environment in and around which the minerals are located. Mining engineers must therefore be concerned not only with the production and processing of mineral commodities, but also with the mitigation of damage to the environment both during and after mining as a result of the change in the mining area.

Asteroid mining is the exploitation of raw materials from asteroids and other minor planets, including near-Earth objects.
Minerals can be mined from an asteroid or spent comet then used in space for construction materials or taken back to Earth. These include gold, iridium, silver, osmium, palladium, platinum, rhenium, rhodium, ruthenium and tungsten for transport back to Earth; iron, cobalt, manganese, molybdenum, nickel, aluminium, and titanium for construction.
Due to the high launch and transportation costs of spaceflight, inaccurate identification of asteroids suitable for mining, and in-situ ore extraction challenges, terrestrial mining remains the only means of raw mineral acquisition today. If space program funding, either public or private, dramatically increases, this situation is likely to change in the future as resources on Earth are becoming increasingly scarce and the full potentials of asteroid mining—and space exploration in general—are researched in greater detail. However, it is yet uncertain whether asteroid mining will develop to attain the volume and composition needed in due time to fully compensate for dwindling terrestrial reserves.

Bitcoin Cash (BCH) is a hard fork of the cryptocurrency bitcoin. The bitcoin scalability debate led to the hard fork on August 1, 2017, which resulted in the creation of a new blockchain. The stated goal of the fork was to increase the number of transactions its ledger can process by increasing the block size limit to eight megabytes.

Cloud Mining is the process of bitcoin mining utilizing a remote datacenter with shared processing power. This type of cloud mining enables users to mine bitcoins or alternative cryptocurrencies without managing the hardware. The mining rigs are housed and maintained in a facility owned by mining company and the customer simply needs to register and purchase mining contracts or shares. Since Cloud Mining is provided as a service there is generally some cost and this can result in lower returns for the miner. There are many cloud mining scams.

The legal status of bitcoin varies substantially from country to country and is still undefined or changing in many of them. Whilst the majority of countries do not make the usage of bitcoin itself illegal, its status as money (or a commodity) varies, with differing regulatory implications. While some countries have explicitly allowed its use and trade, others have banned or restricted it. Likewise, various government agencies, departments, and courts have classified bitcoins differently. While this article provides the legal status of bitcoin, regulations and bans that apply to this cryptocurrency likely extend to similar systems as well.

A tool library allow patrons to check out or borrow tools, equipment and “how-to” instructional materials, functioning either as a rental shop, with a charge for borrowing the tools, or more commonly free of charge as a form of community sharing. A tool library performs the following main tasks:
Lending: all kinds of tools for use in volunteer projects, facility maintenance and improvement projects, community improvement events, and special events.
Advocacy: for the complete and timely return of all borrowed tools, to guarantee the long-term sustainability of available inventory. Staff also seeks compensation for lost tools and tools returned late.
Maintenance: performing routine maintenance and repairs on all equipment to ensure good condition and to extend the lifespan of the inventory. This function is typically performed by volunteers and community service workers.
