An open pit mine is typically excavated with a series of benches to reach greater depths. Open pit mining initially involves the removal of soil and rock on top of the ore via drilling or blasting, which is put aside for future reclamation purposes after the useful content of the mine has been extracted. The resulting broken up rock materials are removed with front-end loaders and
In the open-pit mines, in order to improve productivity, they used to large numbers of heavy equipment. Due to the huge investments involved, no mine can afford to
It takes planning and scheduling to operate the many benches simultaneously; all in different locations and elevations throughout the mine. Open pit mining is an efficient, cost-effective way to mine for minerals, ore, and coal. It is a reliable and much safer way to do “hard rock” mining for metal ores such as: Copper; Gold; Iron; Aluminum
Mar 25, 2021 Open-pit mining requires creating a large pit in the ground from which the miners extract the needed material. This is one method miners may use to extract silver from the earth. The other technique is underground silver mining. Occasionally, removing a hilltop with explosives to expose the rocky materials beneath is the first step in creating
Open-Pit Mining Equipment One of the world’s largest vertically integrated fertilizer enterprises operates an open pit mine with an annual capacity of millions of tons of phosphate rock. To accomplish this level of production, the company depends on technologically advanced, high-value equipment like its electric mining shovel

The Open Pit is a conventional truck and shovel operation and is serviced by a large modern mining fleet of 175t and 90t haul trucks, loaded by 200t and 120t shovels and excavators. There are also smaller 40t and 35t excavators for ancillary work. The Underground Mine
A Brief History of Open Pit Slope Design Slope design is an integral part of the engineering of an open pit, regardless of its size. Most cases the slope angles are a key component dictating the economic viability of a proposed or current mining project

Following the landslide, mining has been accomplished by a combination of dragline, dozer, and truck and loader operations, depending on the depth and material being mined. The overburden, or rock that lies above the coal seams to be mined, is drilled and blasted to break up the rock to allow it to be moved using the mining equipment
Apr 09, 2017 Open-Pit Mining Methods. 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
Oct 08, 2019 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 topics that will
May 07, 2014 The transition depth determination process was mathematically modelled for the case study. The objective function was chosen to be the maximization of the total profits earned from the combination of both open-pit and underground mining of the deposit. Chah-Gaz transition problem was finally solved by developing MATLAB optimization based code
Equipment selection in mining engineering is one of the most important decision that is affected the mine design, production planning and economic parameters in open pit mining. Mine planning engineers generally use of their intuition and experiences in decision making even though equipment selection is a complex multi criteria decision problem
Open-pit mining; Safer equipment; Increased safety awareness; The Positive Points. The mining company’s typically store collected waste materials (waste rock or overburden) close to the open pit. When the layer parallel to the soil’s crust is revealed (the ore horizon), several benches (steps) are cut into it making waste removal easier
equipment, which may include a mining loader, shovel or excavator. Loaders lift the ore or waste material onto the trucks for removal from the mine. In an open-pit mine, loader types can include electric rope, hydraulic excavators including backhoe excavators, and front-end loaders (also called wheel loaders) (Er˘celebi and K rmanl , 2000)
These will be unique to the sequence of the open pit underground interaction, which can take any combination of the following forms: Scenario 1 – Open pit transitioning to underground; concurrent mining. Scenario 2 – Underground mining below existing open pit. Scenario 3 – Open pit mining through existing underground working
Jun 28, 2021 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 when the resources are exhausted
