In addition, the method has been used successfully as an alternative for developing new mines or extending the operation of open pits; for this reason it has been referred to as an underground version of openpit mining. Another added benefit of block caving is the large reduction in surface waste disposal.

2. Mining Methods
2. 2. Mining Methods. Left: Open Pit Mining. Right: Underground Mining. In each of these mining methods, various earthmoving equipment including shovels, dozers, hauling trucks, and loaders are used to remove and transport the ore. However, the first step is to loosen the rock in the ore body so that it can be moved and processed.
open pit mining methods
May 27, 2020· OpenPit Mining. Openpit mining, one of the most common forms, is one of the most damaging. Miners hollow out a section of land, digging down to create a workable area and extract valuable raw materials. This method leaves behind large pits in the earth and can contaminate the groundwater with chemicals used in the mining process.
Open Pit Mining | IntechOpen
· Open pit mining method is one of the surface mining methods that has a traditional coneshaped excavation and is usually employed to exploit a nearsurface, nonselective and lowgrade zones deposits. It often results in high productivity and requires large capital investments, low operating costs, and good safety conditions. The main topics that will be discussed in this chapter will include ...

Disposal Methods on Solid Wastes from Mines in Transition ...
· Backfill mined out area Waste rock and tailings could also be used in the backfill mined area of a mine in transition from open pit to underground mining. Backfill the mined area is not only significant to the environmental restoring and improving the mining condition, but also a good idea of disposal method on solid waste from mines.
(PDF) SURFACE MINING METHODS AND EQUIPMENT | .
Most bauxite, iron, and copper ore is mined by open pit techniques, lead and zinc ore are principally extracted by underground mining methods, and precious metals, particularly gold and most notably in the USA and Australia, tend to be recovered in recent years from lowgrade deposits by surface mining.
Buenavista Copper Mine Expansion, Cananea, Sonora, Mexico
The Buenavista openpit copper mine in Sonora, Mexico is one of the biggest porphyry copper deposits in the world. Southern Copper Corporation, a subsidiary of Grupo Mexico, is the owner and operator of the project. Producing since 1899, it is the oldest operating copper mine in North America.
Mining Techniques | Geology for Investors
· The most common surface mining technique is openpit mining (Figure 1), where a commodity is extracted via an open pit in the ground. This is an extremely cost effect way of removing a resource because large quantities can be removed with minimal effort. Other surface techniques include quarrying and strip mining.
OPERATIONS MODELING AND ANALYSIS OF OPEN PIT COPPER MINING ...
Open pit copper mining plants usually comprise two major components, the open pit mining operation and the copper ore enrichment plant. An open pit copper mine is an excavation or graze made into the surface of the ground for the purpose of extracting ore. .

Common Types of Mining Equipment Used in the Mining .
· There are three main ways to mine on the surface. These methods include quarrying, openpit mining, and strip mining. In quarrying, miners may cut blocks of hard stone for ornamental purposes, such as granite for building. However, quarrying can also refer to extracting gravel, crushed stone, and sand using similar techniques to openpit mining.
Open Pit Mining
The surface mining methods are: (i) open pit mining, (ii) drift mining, (iii) slope mining, (iv) contour mining, and (v) auger mining. The characteristic that distinguishes open pit mining is the thickness of the coal seam insofar as it is virtually impossible to backfill the immediate mined out area with the original overburden when extremely thick seams of coal are involved.
Basics of an open pit mine
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.
