Mining Operation: Types, Impacts and Remedial Measures! Mining is the process of taking mineral and other substances from the earth. These substances include metal compounds, non-minerals such as coal, sand, oil and natural gas and many other useful things. Mining provides iron and copper for making aeroplanes, refrigerators.
There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
Cryptocurrency mining is now one of the most lucrative investments in the crypto market today. The growing adoption of cryptocurrencies particularly BTC (bitcoin) as payment, created an increasing demand for these digital assets. Mining cryptocurrencies is the process of recording and verifying transactions on a public digital record of transactions, known as a blockchain.
4. Association Rules: This data mining technique helps to discover a link between two or more items. It finds a hidden pattern in the data set. Association rules are if-then statements that support to show the probability of interactions between data items within large data sets in different types of databases.
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit.These deposits form a mineralized commodity 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.

Open-pit mining refers to a method of extracting rock or minerals from the earth through their removal from an open pit or borrow. It is best suited for accessing mostly vertical deposits of minerals. Although open-pit mining is sometimes mistakenly referred to as "strip mining", the two methods are different (see above).
