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.
The three types of surface mines are open-pit mines, strip mines, and mountaintop removal mines. Open-pit mines involve extracting minerals from a large, open excavation. Strip mines involve removing layers of soil and rock to expose the resource. Mountaintop removal mines involve removing the summit of a mountain to access the coal seams underneath.
Open pit mines are surface mines where the ore is extracted from an open pit. Quarry mines are also surface mines, but they specifically focus on extracting construction and industrial materials such as sand, gravel, and limestone for building purposes. Both types of mines involve removing large quantities of rock or minerals from the earth's surface.
Coal mine: A type of mine where coal is extracted from underground or open-pit mines to be used as a source of energy. Gold mine: A type of mine where gold ore is extracted and processed to produce gold, often found in underground mines or as open-pit mines. Diamond mine: A type of mine where diamonds are extracted and processed from volcanic pipes or alluvial deposits, with some mines operating underground while others are open-pit mines.

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

Extraction of uranium:- extraction from underground mines- open pit mines- leaching
Open Pit Mines are big excavations of dirt that go very deep into the earth be using big trucks. They start from groung level and work their way down. This is what it looks like

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.
