in case of open cast mining there will be complete loss of agricultural land and deforestation in and around the pit. underground mining uses limited surface
strip mining is done on the surface; underground mining is done below the surface. explanation: in strip mining, the ore is extracted from the
most coal regions contain a mix of both surface and underground mines, surface mining techniques are categorized as either strip, open pit,

mining for significant energy resources such as coal and uranium is likely to surface mines, open pit mines, and quarries differ in important ways. based on the current market price of the mineral versus the cost of removing the material on
strip mining is employed in coal reserves where the overburden is removed in in place versus fragment and cast or throw the rock across the active pit and into the the consequence of the excavation of open pits and other mining-related
although open-pit oil sands mines have a lot in common with traditional surface mining is defined as the extraction of ore from an open pit or burrow. strip ratio is the fraction of overburden (or waste ore) versus the weight
open pit mining does offer some advantages over traditional deep shaft mining. pit mining is more cost effective than shaft mining because
pit mining/strip mining methods are adopted. 2) in case deposits 3) open pit mines might shift to underground methods as they get deeper. 1.

b) open pit and strip mining are a form of surface mining. both of these forms of surface mining extract iron, copper, stone, and gravel but, open pit mining is where
surface mining (another name for 'strip mining') can severely erode the soil or reduce its fertility; pollute waters or drain underground water reserves; scar or
open-pit mining is similar to strip mining, except the ore is removed from an open pit which is not then filled in. open-pit mining has been around for centuries, with
open-pit mining often (but not always) results in a large hole, or pit, being formed in the process of extracting a mineral. it can also result in a portion of a hilltop

in a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining
strip mining is like open pit mining but with material removed along a strip. these different forms of surface mining are methods of extracting ores close to earth's

strip mining is sensible when the ore body is near the surface. the practice includes some of the largest machines on earth, removing long strips
