each of the models is developed from first principles based on typical mining criteria for rock densities, swell factors, drill penetration rates, etc. industry-standard estimating methods are used for equipment selection, personnel allocation, and cost estimation.
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.
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. the word is used to distinguish this type of mining from extractive methods that need tunneling into the earth.
open cast gold mining equipment is the most traditional crushing machine. due to its simple structure, solid and reliable, easy to maintain and repair, open cast gold mining equipment is trusted by users.
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 low-grade deposits by surface mining. figure 1a.

open-pit, open-cast or open cut 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 tunnelling into the earth, such as long wall mining. open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface.
open-pit mining methods are applicable to mining ore deposits that apex at or near the surface. if the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of open-pit mining. the removal of this material is known as stripping.
and open pit miningalso called open cut mining or open cast miningis a surface mining technique used to extract rocks and minerals. it requires largescale equipment, including shovels and drills. motor graders also play a role, maintaining haulage roads so that both equipment and mined material can be transported to and from the mines.
this is a very basic idea of how the open pit mining process takes place. this was a very new mine when the footage was shot, and using very small machines.
