· Highwall Miners/Continuous Mining Machine. Certain open pit mining projects will have steep walls, called a high wall, as the machines continue to dig farther down to obtain minerals and metals. Yet there are times when vein seams of minerals or metals can be seen running along the wall, as companies want to mine the available minerals to bring it up to the surface. A continuous mining .
What is open pit mining . Open pit mines are those mining operations that take place on the surface, unlike the underground mines. This is possible when the reservoir sprouts on the surface or at a very small depth. It began to be realized in the middle of the XVI century and it is used all over the world. In order to be carried out, the excavation (using machinery or explosives) of the lands ...
· OpenPit. As the name suggests, open pit mining involves mining minerals or ore that can be found near the surface layer of the site. That being said, some quarries can be over 1000 meters deep. This form of mining doesn't require tunnelling into the earth and is a simple method of mining that yields high production rates. YouTube.
· Dragline excavators in mining are used to remove overburden – anything that's in the way of getting to the real product. For example, removing soil and rock from the surface above the coal seam. This overburden is repurposed, in some cases set aside to refill the open pit .

Strip mining is a kind of surface mining. The ore is very near to the surface of the land but has one or more layers of rock and filth on top of it. To mine the ore, these layers have to be removed. The steps in strip mining are similar to openpit mining. The steps are:
Openpit mining is considered more economical, driving equipment manufacturers to develop more innovative equipment. Some unconventional ways manufacturers are setting themselves apart from competitors include building batteryoperated drill rigs and portable analyzers that identify surface rock chemicals with Xrays. Additionally, many mining ...

· In mining operations, huge quantities of ore and waste material at mine sites are transported using extremely large equipment 24 hours a day. Material transportation represents up to 50% of operating costs in open pit mining [1]. In order for mining companies to have sustainable and economical mining operations, they must do two things: (i ...
however, for largescale open pit mining in particular, the truck and loader" material movement practice is the preferred method of materials handling (Czaplicki, 1992; Ta et al., 2005). Throughout this paper, we consider a loader" to be any type of high productivity excavating equipment, which may include a mining loader, shovel or excavator. Loaders lift the ore or waste material onto the ...
