distinguish between surface mining and subsurface mining

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. SUBSURFACE MINING is the extraction of mineral and energy resources from deep underground deposits. Just so, why is subsurface mining dangerous? Subsurface mining is actually less disruptive …

the actual difference between surface and underground mining

Main Difference In surface mining, theore 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 is above ground; subsurface mining is below ground. Negative environmental impacts from oil and natural gas production may occur due to. accidental spills at extraction sites and during transport. All of the following are harmful environmental impacts that are the result of emissions from burning coal except

ecological effects of subsurface mining dummies

Thegroundwater from the mines is more acidic than surface waters and disrupts ecosystems by changing the pH conditions of soil and water sources. Subsurface mining operations don’t create the visible changes in the landscape that surface mining operations do, but the conditions of subsurface mines are extremely hazardous for the working miners

ecological effects of subsurface mining dummies

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 where they can retrieve the valuable …
