What does open cut mean in mining?
Open-cut mining is a process of resource extraction where it is dug up from the surface. Also known as open-pit mining or open-cast mining, it is the most common form of extraction for minerals or coal in Australia.
What are 4 types of surface mining?
There are 5 main types of surface mining, which are used in various degrees and for different resources. These mining categories are: strip mining, open-pit mining, mountaintop removal, dredging and high wall mining.
What are the benefits of open-cut mining?
After the mineral deposits have been exposed, the area is drilled, fractured and the mineral extracted. This method has a high recovery rate when compared to the underground, as 90 percent of mineral deposits are recovered. Overall when compared to other methods, open-cut is much safer.
What is the difference between open cut and underground mining?
The Maxwell Underground Project is a proposal to develop an underground coal mine. Underground mining is very different from open-cut mining. Open cut mining involves removing layers of soil and rock to expose the coal seams, which usually involves blasting to help remove the waste material.
What are 5 types of mining?

What are the 5 different types of mining?
What opens mine development?
All horizontal or subhorizontal development openings made in a mine have the generic name of drift. These are simply tunnels made in the rock, with a size and shape depending on their use—for example, haulage, ventilation, or exploration.
What is a mine entry?
Abstract. Mine entries indicate the entrance into a mine working, for which there are two types: shafts and adits. Mine shafts are vertical or near vertical entrances to a mine whereas adits are a walkable entrance to a mine as shown on plans held by the Coal Authority.
What is open-cut mining?
Opencut mining gets its name because that’s exactly what this type of mining looks like, a big open pit. This type of mining allows for the extraction of minerals that aren’t very far under the surface. The process keeps the activity from going deep underground. This has many advantages.
What is open pit mining?
Open-pit Mining. Open-pit mining, also known as opencast mining, open-cut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow.
What is surface mining?
This surface mining technique is used when mineral or ore deposits are found relatively close to the surface of the earth. Open-pits are sometimes called ‘quarries’ when they produce building materials and dimension stone. Elimination of safety hazards that can accompany complex underground mining operations
How has modern mining changed over time?
Mining has changed and evolved tremendously since its first iterations. Technological advances have improved efficiency, created a safer workplace and minimising the environmental impact. Both open-cut and underground mining is used in modern mining. The approaches are different, and there are advantages to each.
