In the previous topic, we stone that blasting is the mining operation used to break the rock mass in order to facilitate the removal of the overburden. We stone that some of the main equipment used to remove the overburden are truck lines, trucking shovels, excavators. In this topic, we will look at some of the characteristics of these excavation metals, and at which deposits they are more suited

Open-pit mining, or open-cast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful minerals or rocks are found near the surface; that is
Mining : What is Mining? What are the 4 mining methods
What are the main mining methods? Four main methods of mining are available: underground, open surface (pit), placer and in-situ mining. Underground mines are more expensive and often used to reach deposits that are deeper. Surface mines are usually used for deposits that are shallower and less valuable. Placer mining is used in river channels, beach sands, or other environments to sift
Surface mining Wikipedia
Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels. Surface mining began in the mid-16th century [dubious

open-pit mining Mining. a method of mining in which the surface excavation is open for the duration of mining activity, employed to remove ores and minerals near the surface by first removing the waste or overburden and then breaking and loading the ore. Used to mine thick, steeply inclined coalbeds and also used extensively in hard-rock mining for metal ores, copper, gold, iron, aluminum, and
Underground Mining Methods — New Pacific Metals
After mining out levels, the pillars may be removed (to recover the remaining ore or material) and the roof is allowed to safely collapse and fill in the mined out area. Block Caving. Block caving is essentially the underground version of open-pit mining. It’s the only underground mining method that can reach similar production rates to
Green Mining Massachusetts Institute of Technology
Although open pit mining (link to mining solution page) contributes about 85% of all mineral mining, it is one of the most environmentally taxing. About 73% of extracted rock goes to waste. Meanwhile, underground mining wastes only 7% of the extracted rock but is more expensive (Hartmann and Mutmansky, 2002). In situ mining (see mining solution page) can be more environmentally friendly

Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.

Block caving is essentially the underground version of open-pit mining. It’s the only underground mining method that can reach similar production rates to surface mining operations, up to over 100,000 tonnes per day. The method involves undermining an ore body, then allowing it to collapse under its own weight.
