How can mining lands be restored?
After the coal is stripped, mine companies are legally required to do some restoration, which usually involves replacing the exploded soil and rock—rubble—covering it with a layer of topsoil, and seeding it with anything that will hold the ground together.
What are some ways an area can undergo reclamation after being mined?
What are some ways an area can undergo reclamation after being mined? Refilled/reshaped w/vegetation planted; filled w/water to become a lake; turned into landfill; left open as home for bats or sealed off if underground.
What is the most likely consequence of open pit mining on plant life?
The soil looses it’s fertility. This converts the mining site into a barren land. Therefore, the complete loss of plant life in the area occupied by the surface mine is the most likely consequences of open pit mining on plant life.
How does open pit mining affect the environment?
Mining is widely regarded as having adverse effects on environment of both magnitude and diversity. 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.
What effect does open pit mining have on the environment?
Open cut mining can have major impacts on streams, alluvial aquifers and alluvial soils. Mining which removes alluvium to reach coal beneath has an obvious impact on an alluvial aquifer, requiring it to be dewatered during mining, and with very little probability of successful restoration afterwards.
What do you call an open pit mine where rocks can be extracted?
Open-pit mining, also known as opencast mining, is a surface mining technique that extracts minerals from an open pit in the ground. Open-pit mining is the most common method used throughout the world for mineral mining and does not require extractive methods or tunnels.
What is the difference between a strip mine and an open pit mine?
Strip mining is a practical type of mining when the ore body that is to be extracted is near the surface. Open-pit mining is the process of extracting rock or minerals from the earth through their removal from an open pit or borrow.
How deep can an open pit mine go?
The world’s biggest open pit iron mine can be found near Hibbing, Minnesota. At its maximum, the area covered by the Hull Rust open pit mine is five miles (8km) long, 2 miles (3,2km) wide and 535 feet (180m) deep.
What is the world’s deepest pit?
Bingham Canyon mine
Why is open pit mining cheaper?
Open-pit mining occurs on surface and is generally the cheapest way to extract ore. This is because rock doesn’t have to be moved far up hill against gravity, equipment used can be larger than underground, and it doesn’t require more expensive features like ventilation, communications, etc.
What happens if you don’t refrigerate cranberry juice after opening?
Refrigerate it: This tip might be the most important of all. Once you open the juice bottle, seal it tight and refrigerate it. If you don’t refrigerate it, the safety of the juice can no longer be guaranteed, even if the juice has been staying in the pantry for a few hours.
Does unopened cranberry juice go bad?
Properly stored, unopened cranberry juice that has been sold unrefrigerated will generally stay at best quality for about 18 to 24 months after the date on the package when stored at room temperature, although it will usually remain safe to drink after that.
