Open pit mining can be better for the environment than underground mining because it has a lower impact on the ecosystem and wildlife. Open pit mines generally have smaller footprints, making land reclamation easier. Additionally, open pit mining often has better air quality controls and uses less water than underground mining.
There is nothing negative about open pit mines in and of themselves. However, open pit mines have three problems. The first problem comes with what the mine owners do with the overburden over the ore. The second problem comes with what the mine owners do with the tailings. And the third problem involves what to do with the pit after the ore is extracted. Different governments handle it in different ways. In the United States, The State of Pennsylvania has a law that requires the mining company to restore the land. Where there were open pit mines, there are now beautiful meadows. In West Virginia were there were open pit mines, there are denuded hill tops and acid filled streams.
Open-pit mining is a type of surface mining where large quantities of material are excavated from a large, open pit. It is commonly used to extract minerals such as copper, gold, and coal.
Open pit mining is generally cheaper than shaft mining because it requires less equipment and labor. In open pit mining, large quantities of ore can be extracted quickly and efficiently using heavy machinery. Also, open pit mines are typically less deep than shaft mines, which reduces the complexity and cost of excavation and support systems.
Two minerals commonly mined using open-pit mining are copper and coal. In open-pit mining, large holes are dug to access the mineral deposits near the surface, making it an efficient method for extracting these minerals in large quantities.
Gold mining can be both open-pit and underground. Open-pit mining involves digging a large pit to extract ore, while underground mining involves tunnels and shafts to access ore deposits below the surface. The choice between the two methods depends on factors such as the depth of the ore body and economic considerations.

they are quite simply called open pit mines, they can also be known as quarries.

Yes. Ancient man began doing it and open pit mining continues today.
