Surface mines offer advantages and disadvantages when compared to underground mining. Amongst the advantages are that it is cheaper, can recover more of the resource (usually up to within the mining excavation), is safer and can use largerscale mining equipment offering higher production rates.
5 Pros and Cons of Strip Mining Materials such as coal and tar sand are located relatively near the surface of the earth. The method to recover such materials is called strip mining, a form of surface mining where surface vegetation, soil and rocks are removed in strips and often times together with controlled explosions in order to make the ...
Jan 14, 2020· Strip mining is a form of surface mining that is usually employed for the recovery of materials such as coal and tar sand, which are relatively near the surface of the earth.

These mining categories are: strip mining, openpit mining, mountaintop removal, dredging and high wall mining. All methods of surface mining will remove the waste material, or overburden, above the desired resource. Surface mining is often preferred to subsurface (underground mining) by mining companies for several reasons.
Surface mining techniques don''t work for extracting all valuable geologic resources. Diamonds and most metal ores, including gold, require extensive subsurface mines to access the rocks with these resources in them. Subsurface mines are probably what you envision when you think of mining: systems of tunnels and vertical shafts with elevators to take miners underground .
Although both methods have their benefits and drawbacks, underground drilling may just be the cost worthy selection for you Mining for coal depends on many variables. The geology and environmental aspects play a vital role, but depth and quality of the seam is what brings home the bacon. Depending on where the seam (profitable bed of coal) is located, extracting this black gold can require a ...
