Mining Techniques

Mining literally means extraction.Our Mother Earth has lots of resources deep within her and mining is the method of extracting all these valuable resources from the earth through different means. There are different methods to extract these resources which are found in different forms beneath the earth's surface.It goes without saying that it is the most important achievements

Asteroid mining

Asteroid mining is the exploitation of raw materials from asteroids and other minor planets, including near-Earth objects. [1] Hard rock minerals could theoretically be mined from an asteroid or a spent comet.Precious metals such as gold, silver, and platinum group metals could be transported back to Earth, while iron group metals and other common ones could be used for

Depleting Earth's resources

1/8/2018As an ecological economist and scholar of sustainability, I am particularly interested in metrics and indicators that can help us understand human uses of Earth's ecosystems. Better measurements of the impacts of human activities can help identify ways to sustain both human well-being and natural resources.

Mining and Mineral Use

Underground mining is used to recover ores that are deeper into Earth's surface. Miners blast and tunnel into rock to gain access to the ores. How underground mining is approached – from above, below, or sideways – depends on the placement of the ore body, its depth, concentration of ore, and the strength of the surrounding rock.

10 Different Types of Mining Operations and Mines –

There are two basic types of mining: mining underground and mining at the earth's surface. Nearly two-thirds of the world's solid minerals are mined through surface mining. It is especially predominant in obtaining items such as coal, copper, sand, gravel, crushed stone, iron, aluminum, and phosphates.
