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 pros of open pit mining?
Some pros of open pit mining include lower costs compared to underground mining, higher productivity due to easier access to the deposits, and the ability to extract a large quantity of minerals. Additionally, open pit mining can be more environmentally friendly in terms of land reclamation and restoration post-mining.
What are the two main types of mining and how do they differ?
The two main types of mining are surface mining and underground mining. Surface mining involves extracting minerals or resources from the Earth's surface, while underground mining involves extracting resources from beneath the Earth's surface. Surface mining is generally more cost-effective and less dangerous, but it can have a larger environmental impact compared to underground mining. Underground mining, on the other hand, can be more expensive and pose greater safety risks, but it is less disruptive to the environment.
What are two main types of mining and how do they differ?
What are two main types of mining and how do they differ? Open cast mining, and underground mining. The reason they differ, is because underground mining is where they create shafts that lead to ore beds. Open cast mining, is the opposite of underground mining. I really hope this answer is useful!

What mining method is used to extract ore from beneath the earths surface?
The most common mining method used to extract ore from beneath the earth's surface is underground mining. This method involves creating tunnels and shafts to access the ore body underground, where miners extract the ore using various techniques. Underground mining can be more expensive and dangerous than surface mining but is necessary for accessing deep deposits of valuable minerals.
