What are the advantages and disadvantages of mining ores. The advantages of surface mining are: . It is cheaper to extract the ore or metal than underground.
Transcript of Subsurface Mining and its Environmental Impacts. Advantages : Safer than surface mining, faster than 60% of other mining in the, less disruptive to the environment, leads to more minerals. Disadvantages : Costs more, harder to do than surface mining, takes a lot of time. A form of coal mining where a long wall...
The advantages of surface mining include higher production rate (some 2050 Mt per annum), safety working conditions, higher recovery rate of the mineral deposit (generally more than 90% of coal), lower operating cost, and higher productivity.
Cut costs; improve product quality – the advantages of selective mining. Cutting, crushing and loading in a single step additionally enables the production costs per tonne of iron ore mined to be reduced by around forty percent. The use of surface miners cuts the overall investment costs in opencast mining equipment required for iron ore mining by nearly fifty percent.
For those who are unfamiliar, strip mining is a form of surface mining that focuses on the collection of tar sand and coal, which both rest somewhat close to Earth's surface. Those who support strip mining point to the increased ease of access and all of its attendant benefits.
Although still more costly than surface mining due to the inherent difficulty of underground operations, block caving is the only underground mining technique that achieves production rates equivalent to surface mining. However, it is only suitable for ore bodies with large horizontal and vertical extents.
Advantages: . Surface mining is safer . disadvantages of mining is that the chemicals used to extract the minerals will go down lakes which well put a big impact on the environment UPDATE This answer needs a. slight correction. Chemicals are NOT used to extract minerals during mining in the United States.

Surface mining is a highlyregulated, highlysophistied mining method used to mine coal that is near the surface of the earth. Environmental Risks of Mining Unregulated mining has the ... advantages over conventional mining in that the ore body is dissolved and then pumped out, leaving minimal surface ...
Surface mining entails removing the topsoil and material under the surface to access a coal seam. This process is performed by using earthmoving equipment, including crawler tractors, mining haul trucks, wheel loaders and drag lines.
Surface mining is generally considered to provide better recovery, grade control, flexibility, safety, and working environmen ts than underground mining. Figure 3 shows a comparison of the total injury rates in US coal mines. The injury rates have declined both in surface and underground mines.
surface mining as an entirely selective mining method A direct comparison between the three methods used in Estonia has shown that the surface mining technology offers clear advantages in terms of the runofmine (ROM) material quality.

Efficient Operations. One of the major benefits to open pit mining is the increase in efficiency over deepshaft mining techniques. Because mining occurs at the surface, no space restrictions from narrow tunnels and shafts affect the rate at which ore can be extracted. Sampling each "bench" or level in an open pit before mining deeper makes it...

Strip mining (also known as open cast, mountaintop or surface mining) involves scraping away earth and rocks to get to coal buried near the surface. In many cases, mountains are literally blasted apart to reach thin coal seams within, leaving permanent scars on the landscape as a result.
Mar 16, 2015· Environmental impacts of coal. Mountaintop removal mining and other forms of surface mining can lead to the drastic alteration of landscapes, destruction of habitat, damages to water supplies, and air pollution. Not all of these effects can be adequately addressed through coal mine reclamation.
