What are advantages of surface mining of coal compared to underground mining?
Advantages of surface mining of coal compared to underground mining include lower operating costs, higher productivity due to larger equipment and easier access to coal deposits. Surface mining also results in less environmental impact compared to underground mining in terms of land disturbance and waste production.
Why is surface mining cheaper?
Surface mining is generally cheaper than underground mining because it involves removing material from the surface rather than having to dig deep underground. This makes it more accessible and requires less equipment and labor. Additionally, surface mining usually has higher production rates and allows for larger equipment to be used, further reducing costs per unit of material extracted.
Compare and contrast surface mining and subsurface mining on the basis of cost safety land disturbance and energy use?
Surface mining is generally cheaper than subsurface mining, as it involves fewer machinery and labor costs. However, surface mining can cause more land disturbance and environmental damage due to the removal of topsoil and vegetation. Subsurface mining, while more expensive, is often considered safer as mining activities are conducted underground. Both methods require significant energy use, but subsurface mining may consume more energy for ventilation and transportation.
What are some surface mining methods?
Some surface mining methods include open-pit mining, strip mining, mountaintop removal mining, and placer mining. These methods involve removing the overlying material to access the desired mineral deposits near the surface. Surface mining is often used for coal, metals, and other minerals that are located close to the Earth's surface.
What are different types of surface mining?
Types of surface mining include open-pit mining, quarrying, strip mining, and mountaintop removal mining. These methods involve removing overlying vegetation, soil, and rock to access ore or minerals near the surface. Each type of mining has various environmental impacts that should be considered.

What has the author E A Nephew written?
E. A. Nephew has written: 'Costs of coal surface mining and reclamation in Appalachia' -- subject(s): Costs, Environmental aspects, Environmental aspects of Reclamation of land, Reclamation of land, Strip mining
Why opencast mining is cheaper for companies?
because opencast mining doesnt require shafts and tunnels to be built unlike other approaches such as deep mining. it is on the surface so transportation costs from underground to ground level do not exist. insurance costs for miners may be lower as there is no risk of the mine 'caving in'.
How do surface mining and underground mining differ?
Surface mining occurs close to the surface (less than a mile deep), while underground mining is underground.

what are the 5 different mining?
the 5 types of mining are "sub-surface mining, surface mining, open-pit mining, dredging, and strip mining" please like :)
Two types of mining?
Underground mining surface mining
When was Office of Surface Mining created?
Office of Surface Mining was created in 1977.
A mining process in which rock is stripped away to expose mineral deposits near the surface is?
Strip, surface or open cast mining.
