Bingham Canyon Mine
Q. Where is the biggest pit in the world?
Q. When would miners use an open pit mine?
Open-pit mining is the most common method used throughout the world for mineral mining and does not require extractive methods or tunnels. This surface mining technique is used when mineral or ore deposits are found relatively close to the surface of the earth.
Q. How do you start an open pit mine?
To create an open-pit mine, the miners must determine the information of the ore that is underground. This is done through drilling of probe holes in the ground, then plotting each hole location on a map. The information gained through the holes with provide an idea of the vertical extent of the ore’s body.
Q. What are the disadvantages of open pit mining?
Disadvantages of open pit mining Very large amounts of waste rock are mined. This creates costs as well as environmental issues with waste rock disposal; Major disruption of surface: pit footprint, waste dumps. High visual impact, especially strip mining.
Q. Why is open pit mining cheaper?
The cost advantage of open pit mining to investors is a matter of scale. It is cheaper to operate an open pit mine because less manpower and equipment is required. Strip mining, or open pit mining is profitable sooner than a shaft mine because more ore can be extracted from an open pit mine and more quickly.
Q. What are the benefits of open pit mining?
Advantages of open-pit mining include:
- Powerful trucks and shovels can be used to move large volumes of rock.
- Equipment not restricted by the size of the opening you are working in.
- Faster production.
- Lower cost to mine means lower grades of ore are economic to mine.
Q. What happens during open pit mining?
The open-pit mining cycle includes drilling ore and waste rock, loading drill holes with explosives, blasting, ore loading and hauling to stockpiles for processing, waste rock loading and hauling to the waste rock storage pile.
Q. What are the benefits and drawbacks of open pit mining?
1.1 Features, technical and economic indicators of open pit development
| Advantages | Disadvantages |
|---|---|
| High production rate (essentially unlimited, although small surface mines also possible) | Limited by stripping ratio |
| Lowest cost along with open cast mining | High capital investment associated with large equipment |
Q. Why open pit mining is bad?
The effects of open-pit mining and mineral processing plants on the environment include land degradation, noise, dust, poisonous gases, pollution of water, etc. The extraction process could itself modify the water flow and accelerate this transfer.
Q. Why is open pit mining so destructive?
This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined. Environmental hazards are present during every step of the open-pit mining process.
Q. How does open pit mining affect the environment?
Some of these effects include erosion, formation of sinkhole, biodiversity loss and contamination of groundwater by chemical from the mining process in general and open-pit mining in particular. As such, a repeatable process to evaluate these effects primarily aims to diminish them.
