Open pit mining allows for large-scale operations, enabling the extraction of substantial quantities of minerals efficiently. This makes it economically viable for minerals that are dispersed over a wide area. 2. Accessibility. Unlike underground mining, open pit mining provides direct access to the mineral deposits.
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.

Open-pit is one of the most common mining methods used and starts from the earth's surface, maintaining exposure to the surface throughout the extraction period. The excavation usually has stepped sides to ensure the safety of the miners and a wide ramp where equipment can travel, allowing the product to be removed efficiently from the site.
Open-cut mining is a process of resource extraction where it is dug up from the surface. Also known as open-pit mining or open-cast mining, it is the most common form of extraction for minerals or coal in Australia. The technique of open-cut mining is used when the deposits are close enough to the surface to be readily extracted.

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.
A wide range of equipment can be utilised for overburden removal in open-cast mining, according to the ground type and the topographic context. If the excavated material cannot be reprocessed (either for economic or technical reasons), overburden has to be disposed by means of a range of systems, typically combined with excavation techniques ...
