There are some things that are difficult to mine via the open pit method. But when it is possible to apply the techniques of the open pit mine to recover rock and minerals, this mining type is good for basically two reasons. One is because it is relatively safer, and the other relates to the scale of the mine.
We recover materials from the ground every day, and have done so for thousands of years. The open pit mine presents far fewer hazards than underground mining, and the reasons are fairly obvious. In a shaft or drift, there are many things that can go wrong and cause loss of life and/or equipment. There are far fewer in an "outdoor" mining activity as it is practiced in an open pit.
The largest mines in the world are essentially big holes in the ground. These open pit mines use the economy of scale to produce materials, copper being one. The concentrations of copper are not high, so it is essential to move large volumes of ore to recover the metal in a manner that makes it cost effective on the site, and competitive on the world market to do so.

What are the three types of surface mines?
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.
Describe 3 different kinds of mines?
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.
What kind of mines are open pit and quarry mines?
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.
Why are open pit mines negative?
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.

What are two reasons why open-pit mines are more common in western Canada than underground mines?
Oh, dude, like, open-pit mines are more common in western Canada because of the abundance of low-grade ore deposits near the surface, making it easier and cheaper to extract. Also, the terrain in western Canada is often more suitable for open-pit mining compared to underground mining, so, like, why not go with the flow, right?
