Extraction of valuable minerals or other geological elements from the earth is known as mining. For thousands of years, the mining sector has been a vital component of human civilization, providing the raw materials for creating infrastructure and sustaining economies. But mining can also have detrimental effects on the ecosystem, like destroying habitats and polluting the environment. Three popular mining techniques—surface mining, underground mining, and solution mining—will be covered in this article. Surface mining
In open-pit mining, the ore and waste rock are taken out of a sizable pit that has been dug out of the ground. When the ore is dispersed across a vast region and is close to the surface, this approach is employed. Similar to open-pit mining, strip mining removes the overlaying rock in narrow strips rather than in a big pit since the ore is typically closer to the surface. Mining underground
When the ore is too deep to be reached using surface mining techniques, underground mining is done. To access the mineral, tunnels must be dug underground. Longwall mining and room-and-pillar mining are the two primary subtypes of underground mining. Room-and-pillar mining involves extracting the ore in rooms while leaving rock pillars to support the ceiling of the underground mine. Longwall mining is the process of removing a long wall of coal or ore in one piece using a device called a shearer. Solution mining
Minerals dissolved in subterranean water are extracted through solution mining. This process involves pumping a solution back up to the surface after dissolving the minerals in the ground, where the minerals are then retrieved. PPT from mining and mining-related pollution In a presentation titled Mining PPT, numerous aspects of mining are covered, including the various types of mining, the mining equipment utilized, and the effects of mining on the environment. Pollution is one of mining’s most serious environmental effects. Soil contamination, as well as air and water pollution, are all effects of mining. Wildlife and human health could be harmed by this pollution. Why Should Mining Be Stopped?
When mining’s negative effects on the environment outweigh its advantages, mining should be stopped. This is valid when mining leads to serious environmental impact such as habitat destruction or pollution. Additionally, mining may have detrimental societal effects, such as the eviction of indigenous people or violations of human rights. How Do You Mine Dogecoin? You can mine Dogecoin, yes. A computer’s processing power is used to mine the cryptocurrency known as Dogecoin. However, due to the rising costs of mining and the falling price of Dogecoin, mining is no longer as economical as it once was.
