What is dug unto the ground in subsurface mining?
In subsurface mining, tunnels are dug beneath the Earth's surface to extract valuable minerals or resources, such as coal, gold, or copper. These tunnels can extend deep underground to reach the ore deposits, which are then brought to the surface for processing and use.
What category of mining would be you used to extract ore that is close to the surface?
Surface mining would be the category of mining used to extract ore that is close to the surface. This method involves removing the overlying rock and soil to access the ore. It is typically used for deposits located near the surface where the ore is easily accessible.
Why are Mining and quarrying are commonly practiced in plateaus?
Mining and quarrying are commonly practiced in plateaus because plateaus often contain valuable mineral deposits such as coal, iron, copper, and limestone. The flat and elevated nature of plateaus also makes it easier to access and extract these resources compared to other geological formations. Additionally, the lack of dense vegetation on plateaus simplifies the process of extracting minerals through mining and quarrying.
What is land with rich deposits of iron ore called?
Land with rich deposits of iron ore is called an iron ore reserve or iron ore deposit.
What tunnels that extend deep into ground following the veins of ore?
These are known as "ore drifts" or "adits." They are horizontal tunnels that follow the ore veins underground to extract minerals. Miners use adits to access the deposit without having to excavate from the surface, making it a more efficient and cost-effective method of extraction.
Why is surface mining important?
Surface mining is important because it allows for the extraction of valuable minerals, ores, and other resources that are located near the Earth's surface. This method is more cost-effective and efficient compared to underground mining in certain cases. Additionally, surface mining creates job opportunities and stimulates economic growth in the regions where it is carried out.
Why is underground mining is more dangerous than open-cut mining?
Underground mining is more dangerous than open-cut mining because it involves working in confined spaces with poor ventilation, as well as risks of cave-ins, fires, and explosions. The lack of natural light, unstable ground conditions, and the presence of toxic gases also contribute to the higher level of danger in underground mining compared to open-cut mining.
What is the process and machinery required to extract coal from the lithosphere?
Coal extraction involves using machinery such as excavators, draglines, or continuous miners to remove the coal from the lithosphere. The process typically involves drilling into the ground to access the coal seam, then using heavy equipment to remove the overlying rock and expose the coal. Finally, the coal is extracted and transported to the surface for processing.
Are the minerals mined in northern cape renewable?
No, minerals extracted from mining in the Northern Cape are not considered renewable resources. Once minerals like iron ore, manganese, and diamonds are extracted and consumed, they cannot be naturally replenished within a human time scale.
Why would mining company choose to do surface mine?
A mining company might choose to conduct surface mining if the ore deposit is close to the surface, making it more cost-effective and efficient to extract the minerals. Surface mining also has a lower environmental impact compared to underground mining, as it creates less disturbance to the surrounding ecosystems and requires fewer resources for operation.
Why was placer mining the most widely used method for mining for gold?
It was an easy method to find gold. All a man needed was a gold pan, and find a spot on the river to pan. Some got a bit more fancy with a sluice box or rocker to seek gold.
Where do you use drilling method of mining?
Drilling is used in almost every type of mining to sample and determine the extent of a the deposit.
Drilling is used for actual extraction of salt (by solution mining), petroleum, and natural gas.
Lead ore can be found in various countries around the world, including Australia, China, USA, Peru, and Russia. It is commonly associated with other metal ores such as zinc, silver, and copper. Additionally, lead ore can be found in sedimentary rocks and hydrothermal veins.
What is one way miners can mine for resources responsibly?
One way miners can mine for resources responsibly is by implementing sustainable mining practices, such as reducing energy consumption, minimizing water usage, and implementing proper waste management techniques. Additionally, engaging with local communities and obtaining their consent and involvement in the mining process can help ensure the protection of the environment and community well-being.
Why was mining bad for the environment?
Mining can be harmful to the environment due to issues such as habitat destruction, water and soil pollution, deforestation, and air pollution from dust and emissions. These activities can disrupt ecosystems, contaminate water sources, and contribute to climate change, leading to long-term negative impacts on the environment and biodiversity.
What the difference between placer mining and lode mining?
Placer mining involves extracting minerals like gold from loose, unconsolidated materials, such as alluvial deposits or sandbars. On the other hand, lode mining involves extracting minerals from hard rock deposits, typically by following veins or deposits of valuable minerals embedded within the rock.
What are tools used in surface mining?
Some common tools used in surface mining include excavators, bulldozers, haul trucks, draglines, wheel loaders, and blasthole drills. These tools are used to extract minerals and other materials from the earth's surface efficiently and safely.
Why is open pit mining is used?
like strip mining open-pit mining involves removing the surface layer of soil. Miners then use explosives to break up the underlying rock and recover the ore. As they dig a deep hole or pit to mine the ore they build roads up on the sides of the pit. Trucks carry the ore to the surface. Ores of copper and iron are obtained by open-pit mining. (read in earth science book by Mcdougal Littell.)
What are the pros and cons of sand mining?
Pros of sand mining include economic benefits such as job creation and revenue generation from sand sales. However, cons include environmental degradation, habitat destruction, and potential negative impacts on local communities and ecosystems. Overexploitation of sand can also lead to erosion and changes in river flow patterns.
Which type mining be used to extract a vein of ore form deep underground?
The type of mining used to extract a vein of ore from deep underground is known as underground mining. This method involves creating tunnels and shafts to access and extract mineral deposits located deep within the earth. The two main types of underground mining are called shaft mining and drift mining.
What is the name of the ore that tin comes from?
Tin is primarily extracted from the mineral cassiterite, which is a tin oxide ore.
True. Reclamation involves restoring land affected by mining to a condition where it can support a functioning ecosystem. This process involves activities such as soil remediation, replanting vegetation, and ensuring water quality, with the aim of returning the land to a state of ecological health.
Which action would most likely reduce concerns about how strip mining can harm the environment?
Implementing strict regulations and monitoring of mining practices to minimize environmental damage, promoting reclamation efforts to restore the land post-mining, and investing in research for more sustainable mining techniques would help reduce concerns about how strip mining harms the environment.
Which action would most likely reduce concerns about how strip mining can be harm the environment?
Implementing strict reclamation and restoration plans that require companies to restore mined areas back to their natural state after mining is completed. This helps minimize the long-term environmental impact of strip mining and promotes ecosystem restoration.
Why are nodules not mined for ores such as maganese and iron?
Nodules containing manganese and iron are found deep on the ocean floor, which makes mining them technically challenging and expensive. There are also concerns about the environmental impacts of deep-sea mining on fragile ecosystems and biodiversity. As a result, mining companies typically focus on more accessible and economically viable sources of these ores on land.
