If a mineral deposit lies close to the surface, is of sufficiently big size, surface mining (an open-pit mine) can be the most suitable method to extract the ore (Whyte and Cumming, 2007).
Mining - Strip, Open-Pit, Quarrying: It has been estimated that more than two-thirds of the world's yearly mineral production is extracted by surface mining. There are several types of surface mining, but the three most common are open-pit mining, strip mining, and quarrying. These differ from one another in the mine geometries created, the techniques …

Name 3 ore reserves suitable for surface mining This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts.
Types. There are five main types of surface mining as detailed below. Strip mining The Bagger 288 is a bucket-wheel excavator used in strip mining.. Strip mining is the practice of mining a seam of mineral, by first removing a long strip of overlying soil and rock (the overburden); this activity is also referred to as overburden removal.It is most commonly …
Open pit mining method is one of the surface mining methods that has a traditional cone-shaped excavation and is usually employed to exploit a near-surface, nonselective and low-grade zones deposits. It often results in high productivity and requires large capital investments, low operating costs, and good safety conditions. The main …
About 90% of the rock and mineral resources mined in the United States and more than 60% of the nation's coal is produced by surface mining techniques. Coal mining accounts for about half of all surface mining, extraction of sand, gravel, stone, and clay for another 35%, phosphate rock for about 5%, and all metallic ores, for about 13%.
If a mineral deposit lies close to the surface, is of sufficiently big size, surface mining (an open-pit mine) can be the most suitable method to extract the ore (Whyte and Cumming, 2007).
Mining operations have many guises. Surface mining involves uncovering resources by removing overburden. This is done in several ways but, for metal deposits, open pit mining is most common. The Bingham Canyon Mine (Figure 9.10, above), near Salt Lake City, is the world's deepest open pit. It is 4.5 km by 1.3 km in area and is 1.2 …
In other words, reserves represent short-term mining, whereas mineral resources denote longerterm mining potential (e.g., Jowitt and McNulty, 2021). This means that a body of mineralization may be ...
This chapter investigates the benefits that may result from the implementation of circular economy's "3R" principles—reduce, reuse, recycle—in the operation of surface mines. Although the mining sector is represented mainly by a one-way operating mode consisting of mineral exploration, mine exploitation, ore processing, product ...
Surface and Underground Excavations – Methods, Techniques and Equipment (2nd edition) covers the latest technologies and developments in the excavation arena at any locale: surface or underground. In the first few chapters, unit operations are discussed and subsequently, excavation techniques are described for various operations: tunnelling, …
Sub-Surface Mining Techniques. Some mineral deposits are too deep to be surface mined and therefore require a sub-surface mining method.Underground mining is often used for higher-grade, more localized, or very concentrated resources. In the traditional sub surface method a deep vertical shaft is dug and tunnels are dug horizontally outward …
Unsupported or caving methods increase ore dilution, selective mining methods limit ore dilution, but costs more. The availability of a concentration plant impacts the selection of a suitable mining method. • Geology: The geology of the rock mass hosting the mineral processing plant is important in controlling the stability of excavation …

Surface mining is defined as the extraction of ore from an open pit or burrow. Surface mining is sometimes known as open-pit, open-cut or open-cast mining and is only commercially viable if the deposit is located relative close to the surface. Less than 20% of Alberta's bitumen reserves are close enough to the surface to be mined.
Ore Reserves Suitable for Surface Mining • Relatively horizontal stratified reserves with a thin or thick covering of overburden • Stratified vein-type deposits with an inclination steeper than the natural angle of repose of the material so that waste cannot be tipped inside the pit • Massive deposits, deep and very large laterally such that dumping of the …
Mining - Underground, Safety, Techniques: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for …

Surface mining can be divided into open-pit and open-cut methods of metal and coal mining. The surface mining will be more complicated when the depth of the pit increases, and the miners need to go deeper to reach the ore. Advanced analytics and using the new technology can potentially help mining companies find a cost-effective …
Surface Mining. The largest mines are usually surface mines. Heavy machinery and blasting procedures are used to remove large amounts of surface rock, which significantly disturbs the land. A typical surface mine can produce up to 150,000 tons of ore every day. Sometimes whole mountains (or tops of mountains) are removed via …
Mineral Resources can be defined as the concentration of material of economic interest in or on the earth's crust, whereas Ore Reserves are the parts of a Mineral Resource that can at present be economically mined.

The first step in underground mining is to access the ore, and the design depends on the topography of the ground surface, the depth of the ore body, rock strength conditions, and possible requirements for road access [18, 22]. First, miners dig vertical shafts to the depth of the ore and then cut a number of tunnels around the deposit.
