types of subsurface mining The 3 main types of sub-surface mining are quarrying, solution mining, and long wall mining. All use different equipment and techniques. All …
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. Get Price Ch 15.
The difference between surface run-off and subsurface run -off is that surface run-off is that when it is precipitation the water goes on the ground like a river and lake.
Subsurface mining is actually less disruptive to the earth and produces less waste than surface mining, but it's also much less effective and more dangerous. Many workers die in mine collapses ...
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.
There is a lots of difference between surface mining and subsurface mining,here 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 of ...
Distinguish between surface mining and subsurface mining. SURFACE MINING is the extraction of mineral and energy resources near Earth's surface by first …
Surface mining is used where the ore or material to be extracted is located fairly close to the surface.
Mining techniques can be divided into two common excavation types: surface mining and sub-surface (underground) mining. Today, surface mining is much more common, and produces, for example, 85% of minerals (excluding petroleum and natural gas) in the United States, including 98% of metallic ores.

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 …
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 E) Subsurface mining has the …
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 ...

Distinguish between surface mining and subsurface mining. Define overburden, spoils, and open-pit mining. Define strip mining and distinguish among area strip mining, contour strip mining, and mountaintop removal.
Surface mining is generally a much preferred approach to mining because it is less expensive and safer than subsurface mining. In fact, about 90 percent of the rock and mineral resources mined in the United States and more than 60 percent of the nation's coal is produced by surface mining techniques.
1) What is the difference between surface and subsurface mining? Open-pit and strip mines? Shaft and slope? When is each most likely to be used?

Yes there is a difference between surface mining and open pit mining. Open pit mining is a technique of extracting rock or minerals from the earth by their removal from a open pit.Commonly used methods in surface mining are "Strip mining", "Terrace mining" etc.,
Surface mining is used where the ore or material to be extracted is located fairly close to the surface. The overlying ground cover is removed, the material is mined, and the ground cover is ordinarily replaced.
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.

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.
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.

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 ...
Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.
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.
