Dig a large pit over an underground ore body, dig out the ore body, process the material from the ore body to extract the desired material (e.g. coal, metal, oil sand/shale). When done the pits used to be abandoned, now in the U.S. the EPA requires remediation.

Is gold mining open-pit or underground?
Gold can be mined by either method.
What is the difference between strip mining and open pit mining?
1.Depth:strip mining is done for <60 m while open pit is done for>60 to near about 120 m. 2.Design:Strip mining is done maintaining spoil & piles system while open pit has a specific mining structure to follow. 3.Environment:strip mining is normally done for dry area while for open pit mining we have to lower the ground water level.

The three types of mining -strip mining,open pit mining,and shaft mining
What are the advantages and disadvantages of open-pit mining?
Cash
What are the three types of surface mines?

What is a method for uranium mining?
Uranium mining can be either by open pit mining or by underground mining.
The person who first introduced the idea of open-pit mining was?
The idea of open-pit mining was first introduced by the Romans in ancient times. They used this method to extract ores such as copper and iron.
Is gold mining open-pit or underground?
Gold can be mined by either method.
Is uranium more commonly mined world wide using the In Situ Leaching method or the conventional mining method?
The open pit mining or the underground mining are more common now.
Who invented open pit mining?
Open pit mining is a widely used mining technique developed centuries ago, and it is difficult to credit a specific individual with its invention. However, open pit mining has been practiced throughout history in various forms, with the ancient Romans known to have used similar methods for extracting minerals. The technique has evolved and is now a prevalent method in modern mining operations.
Do humans do open pit mining?
Yes. Ancient man began doing it and open pit mining continues today.
Is uranium open pit mining?
no.
What kind of mining are open pit and quarries and example of?
Strip Mining.
What are two reasons why open-pit mines are more common in western Canada than underground mines?
Open pit mining is used when the materials being mined are closer to the surface. It is safer to do open pit mining than it is to do underground mining. Underground mining is only used for mining hard minerals.

Is open mining or closed mining more expensive?
Open-pit mining is generally less expensive in terms of exploration, development, equipment and operation. Typically, when a recovery operation is developed as an open-pit mine, the valuable mineral deposit is closer to the surface. Also, because it is open-pit, the scale of economy applies, meaning that larger equipment can be used, thus lowering the per-unit cost of operation. In addition, while underground mines must leave behind some of the target minerals in order to provide support for the mine structure, open-pit mines do not. It should be noted that while open-pit mining is generally the less expensive mining method. that will not always the case. This is due the geology. The nature of the ore body, and the depth and angle of the deposit will enter into cost considerations when choosing a mining method. It can also depend on the rehabilitation requirements as with open pit mining you are left with huge holes in the ground and with under ground/closed mining you simply have a small entry to close with mining is finished.
What are the disadvantages of open pit mining?
