A mining accident is an accident that occurs during the process of mining minerals. Thousands of miners die from mining accidents each year, especially from underground coal mining, although hard rock mining is not immune from accidents. Coal mining is considered much more hazardous than hard rock mining due to flat-lying rock strata, generally incompetent rock, the presence of methane gas, and coal dust. Most of the deaths these days occur in developing countries, and rural parts of developed countries.
Mining accidents can have a variety of causes, including leaks of poisonous gases such as hydrogen sulfide or explosive natural gases, especially firedamp or methane, dust explosions, collapsing of mine stopes, mining-induced seismicity, flooding, or general mechanical errors from improperly used or malfunctioning mining equipment (such as safety lamps or electrical equipment). Use of improper explosives underground can also cause methane and coal dust explosions.

Ethereum Classic is an open-source, public, blockchain-based distributed computing platform featuring smart contract (scripting) functionality. It provides a decentralized Turing-complete virtual machine, the Ethereum Virtual Machine (EVM), which can execute scripts using an international network of public nodes. Ethereum Classic also provides a value token called “classic ether”, which can be transferred between participants, stored in a cryptocurrency wallet and is used to compensate participant nodes for computations performed. The classic ether token is traded on cryptocurrency exchanges under the ticker symbol ETC. Gas, an internal transaction pricing mechanism, is used to prevent spam on the network and allocate resources proportionally to the incentive offered by the request.
The Ethereum platform has been forked into two versions: “Ethereum Classic” (ETC) and “Ethereum” (ETH). Prior to the fork, the token had been called Ethereum. After the fork, the new tokens kept the name Ethereum (ETH), and the old tokens were renamed Ethereum Classic” (ETC). Ethereum Classic appeared as a result of disagreement with the Ethereum Foundation regarding The DAO Hard Fork. It united members of the Ethereum community who rejected the hard fork on philosophical grounds. Users that owned ETH before the DAO hard fork (block 1920000) owns an equal amount of ETC after the fork.
Ethereum Classic passed a technical hard fork to adjust the internal prices for various opcodes of the Ethereum Virtual Machine (EVM) on October 25, 2016, similar to the hard fork committed by Ethereum a week previously. The purpose of the hard fork was a more rational distribution of payments for resource-intensive calculations, which led to the elimination of the favorable conditions for attacks that were previously conducted on ETH and ETC. A hard fork held in the beginning of 2017 successfully delayed the “bomb complexity” that was added to the Ethereum code in September 2015 with a view of exponentially increasing the complexity of mining and the process of calculation of new network units. The next hard fork is scheduled for late 2017 with the aim of changing the monetary policy with unlimited emissions to a system similar to Bitcoin.

Web mining is the application of data mining techniques to discover patterns from the World Wide Web. As the name proposes, this is information gathered by mining the web. It makes utilization of automated apparatuses to reveal and extricate data from servers and web2 reports, and it permits organizations to get to both organized and unstructured information from browser activities, server logs, website and link structure, page content and different sources. Web mining can be divided into three different types – Web usage mining, Web content mining and Web structure mining.

The Baku–Tbilisi–Ceyhan (BTC) pipeline is a 1,768 kilometres (1,099 mi) long crude oil pipeline from the Azeri–Chirag–Gunashli oil field in the Caspian Sea to the Mediterranean Sea. It connects Baku, the capital of Azerbaijan and Ceyhan, a port on the south-eastern Mediterranean coast of Turkey, via Tbilisi, the capital of Georgia. It is the second-longest oil pipeline in the former Soviet Union, after the Druzhba pipeline. The first oil that was pumped from the Baku end of the pipeline reached Ceyhan on 28 May 2006.

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. 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.

A smart contract is a computer protocol intended to facilitate, verify, or enforce the negotiation or performance of a contract. Smart contracts were first proposed by Nick Szabo in 1996.
Proponents of smart contracts claim that many kinds of contractual clauses may be made partially or fully self-executing, self-enforcing, or both. The aim with smart contracts is to provide security that is superior to traditional contract law and to reduce other transaction costs associated with contracting.
Smart contracts have been used primarily in association with cryptocurrencies.
One real-world smart contract that gained mainstream coverage was The DAO, a decentralized autonomous organization for venture capital funding, running on Ethereum, which was launched with US$250 million in crowdfunding in May 2016 and was hacked and drained of 3,689,577 ETH three weeks later.
mining engineering facts
Coal mining is the procedure of extracting coal from the bottom. Coal is appreciated because of its energy content, and, because the 1880s, has been trusted to create electricity. Material and cement sectors use coal as a gas for removal of flat iron from flat iron ore and then for cement production. In britain and South Africa a coal mine and its own set ups are a colliery, a coal mine a pit, and the above-ground set ups the pit brain. In Australia, “colliery” generally identifies an underground coal mine. In america “colliery” has been used to spell it out a coal mine procedure but nowadays the term is not popular.
Coal mining has already established many developments in the modern times, from the first times of men tunnelling, digging and personally extracting the coal on carts, to large wide open slash and long wall structure mines. Mining as of this scale requires the utilization of draglines, pickup trucks, conveyors, hydraulic jacks and shearers.
