shaft mining or shaft sinking is excavating a vertical or near-vertical tunnel from the top down where there is initially no access to the bottom. when the top of the excavation is the ground surface it is referred to as a shaft; when the top of

the difference between underground mining and surface mining

underground mining hard rock

underground hard rock mining refers to various underground mining techniques used to excavate hard minerals usually those containing metals such as ore containing gold silver iron copper zinc nickel tin and lead but also involves using the same techniques for excavating ores of gems such as diamonds or rubies.

open-pit mining

open-pit mining causes changes to vegetation soil and bedrock which ultimately contributes to changes in surface hydrology groundwater levels and flow paths. additionally open-pit produces harmful pollutants depending on the type of mineral being mined and the type of mining process being used.

the actual difference between surface and underground mining

the actual difference between surface and underground mining there are two ways to extract a mineral - by digging it up or accessing it by tunnels. this pretty much sums up the comparison of surface vs. underground mining.

open-pit mining also known as opencast mining open-cut mining and strip mining means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. the word is used to distinguish this type of mining from extractive methods that need tunneling into the earth.

what is the difference between open-cast mining and

an open cast mine is a generic term for the open-cut type of mine employed to extract almost all types of minerals and coal. but mining is such a vast and diverse sector that the terms are misused at times.

open cut and underground mining iminco

underground mining is generally used for areas where the mineral seam is too far underground for open cut mining to be of use. a tunnel called a decline is created to allow workers and machinery to reach the location of the minerals. stope mining is used for most hard rock mining of minerals such as copper silver lead and zinc.

the actual difference between surface and underground mining

surface mining can be accomplished by the following main methods: open-pit mining: removing ore to leave a crater. quarrying: an open-pit mine for construction materials. strip mining: ore is removed in parallel strips. mountaintop removal: top of a mountain is blasted to remove deep ore. dredging: ore is removed from a river bottom.

underground v.s. surface coal mines: is deep drilling

open-pit mining utilizes blasting and mineral removing digger deeper into the earth causing a crater-like result. mountaintop removal requires explosives to blast debris off mountain tops in order to reach coal seams deep inside the earth sometimes 400 feet below the surface.
