Mining Techniques | Geology for Investors

Jun 14, 2013 . Mining techniques can be divided into two broad categories: surface mining and subsurface mining (See Figure 1). Surface mining consists of stripping soil and vegetation away and possibly a limited amount of rock and then removing ore in large quantities. Conversely, subsurface mining involves sinking.

This article will give a brief overview of the different types of surface mining techniques, what they can be used for and.

Mining - examples, body, used, water, process, Earth, life, methods

When an ore bed has been located relatively close to Earth's surface, it can be mined by surface techniques. 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.

Surface Mining - RitchieWiki

Sep 28, 2010 . Subsurface mining is a variation of surface mining in which the ore or minerals are extracted from a deeper, underground deposit. . Other common types of equipment used in surface mining include wheel loaders, wheel dozers, crawler tractors, motor graders, and heavy-duty dump trucks such as rock.

Mining - Wikipedia

Processing of ore from a lode mine, whether it is a surface or subsurface mine, requires that the rock ore be crushed and pulverized before extraction of the valuable minerals begins. After lode ore is crushed, recovery of the valuable minerals is done by one, or a combination of several, mechanical and chemical techniques.

Ecological Effects of Subsurface Mining - dummies

By Alecia M. Spooner. 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:.

Coal Mining Technologies - TEEIC

What Are the Different Types of Surface Mines? Strip and auger mining are the two most common surface methods of extracting coal in the United States. Open-pit mining is sometimes used in thick shallow-lying western coal seams.

Underground v.s. Surface Coal Mines: Is Deep Drilling Worth the .

May 2, 2014 . Coal mining typically requires two methods of operations: underground and surface mining. The method is differentiated by whether the seam is relatively close to the surface area or buried deep below. An array of underground and surface mining techniques exist, however, technical and economic.

What is Mine Subsidence? - About Mine Subsidence - Illinois Mine .

In simpler terms, when the roof of a subsurface mine collapses, it causes the ground above to sink or subside. Most experts agree that room and pillar mines will eventually experience some degree of collapse, but currently there is no way to know when or exactly where mine subsidence will occur. IMSIF Mining.

What are the main methods of mining? | American Geosciences .

In-situ mining, which is primarily used in mining uranium, involves dissolving the mineral resource in place then processing it at the surface without moving rock from the ground. The method used depends on the type of mineral resource that is mined, its location at or beneath the surface, and whether the resource is worth.
