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 of overlying soil and rock and then removing coal deposits. open-pit mining utilizes blasting and mineral removing digger deeper into the earth causing a crater-like result.

how do surface and subsurface mining differ and how … there is a lots of difference between surface mining and subsurface mininghere i am starting with the basic definition below:-surface mining-when the ore or mineral is present on near surface or shallow depth then excavation is carried out on the surface and the process to get a mineral known as surface m ining.in this method the deposit
as mining progressed the ore deposits began running out making it necessary to seek them deeper inside the ground. this historical event highlights the difference between two techniques of mining which are used even today - surface and subsurface mining. let us compare and contrast them further.
mining is merely defined as digging in the ground to find something of use. the process has been a part of life since antiquity and is still the backbone of the world’s commerce and production. mining could be classified in two forms: mining at the earth’s surface surface mining and mining underground subsurface mining .
mining activities can be broadly divided in two types 1. underground mining 2. surface mining now let's talk about surface mining depending on the topography nature of the strata working conditions depth of the deposit and future use of the lan
what is a critical difference between surface and subsurface mining? a surface mining is more expensive than subsurface mining b surface mining is above ground; subsurface mining is below ground c surface mining causes less environmental damage than subsurface mining d subsurface mining creates acid mine drainage; surface mining does not
the difference between underground mining and surface mining 1. the difference between underground mining and surface mining the process of removal of essential mineral ores or geological substances from soil or sand is called mining. these minerals are of great value and are abundantly available in rocks and earth’s surface.
distinguish between surface mining and subsurface mining. distinguish between surface mining and subsurface mining prompt : caesar is a famous mining equipment manufacturer well-known both at home and abroad major in producing stone crushing equipment mineral separation equipment limestone grinding equipment etc.
surface mining is safer and easier than subsurface mining. surface mining does more damage to the environment than subsurface. surface mining creates more of a mess then subsurface or open cut mining.
strip mining. strip mining is a kind of surface mining. the ore is very near to the surface of the land but has one or more layers of rock and filth on top of it. to mine the ore these layers have to be removed. the steps in strip mining are similar to open-pit mining.
a the difference between surface and subsurface mining is that surface mining is on the earth’s surface and moves the un-needed materials out of the way in order to obtain the desired minerals and energy. subsurface mining doesn’t remove the un-needed soils or rock out of the way instead it uses big machines to dig deep underground into
difference between open cast mining and . differences between open pit and underground mining main difference in surface mining the ore is accessed directly from the earth s surface and contact is maintained with the surface throughout the operation underground or subsurface mining is accomplished with the help of tunnels going into the earth and does not occur on the surface
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 …
distinguish between surface mining and subsurface mining. surface mining is the extraction of mineral and energy resources near earth's surface by first removing the soil subsoil and overlying rock strata.
strip mining and subsurface mining strip mining or surface mining is performed when surface soil and rock are stripped off to reach the mineral of concern. when such operations are done surface water bodies lakes streams etc gets acidity. acid mine drainage occurs when water molecules infiltrates the spoil banks. the water reacts with sulfide minerals to produce sulfuric acid.
