Underground mining is used when the copper ore is not near the earth''s surface. Miners dig a shaft into the ore deposit vertically or a horizontal tunnel (or adit) in order to do this. Mining then follows the vein of ore and the underground mine develops.
Another option is the perchunk branch mine. This is a 2 space branch mine, but is constructed over the space of a single chunk, and is capable of ensuring that every ore deposit is found, while still only mining around 45% of the chunk''s stone. For the initial shaft to bedrock for this mine, a 1ࡨ shaft will fit lengthwise in the central
high stress, and with material flowing in an ore pass, a design circular shape is not maintained for long (in unlined ore passes).

In the case where the crosssection varies along the length of an ore pass section the smaller dimension, being
Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and reseparate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the

May 24, 2014 · An ore pass is a vertical or nearvertical opening, which is created during underground mining operations to transfer materials. It is designed based on the gravitational force between different ground levels, in order to provide a convenient material handling system and reduce haulage distances.
The latter was employed at the Ahmeek mine in Michigan, where the ore was mined in flatdipping open stopes and the back stands well, requiring little support along haulageways. The form shown at E is one developed after long experience at the Hollinger mine in Ontario, where the ore breaks in various sizes from fines to coarse lumps.
note that a review of ore pass surveys reveals that under high stress, and with material flowing in an ore pass, a design circular shape is not maintained for long (in unlined ore passes).

Jun 14, 2013 · Mining techniques can be divided into two broad egories: 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.
The results of a pit design will determine the tons of waste and ore that the pit con tains. When speaking of an open pit mine, the term strip ra tio is used.
If it is practical to obtain representative ore samples, it is prudent to have testwork conducted to establish ore flow properties, which will influence design parameters. At virtually all mines, ore characteristics change over time, and it can be costly to "design in" the optimal flexibility required to

Mar 14, 2014 · Mining techniques. Mining techniques usually consist of two types based on excavation methods. These are surface mining and underground mining (sub surface mining). Iron ore is almost exclusively mined by surface operations. The most predominant surface mining methods used for mining of iron ores are open pit mining methods and open cut mining
By using this data and complex computer programs to more accurately define the orebody, mine engineers can determine mining methods, design blast patterns, design dig patterns, and maximize the safety and efficiency of production – as well as determine how the ore should be processed.

Other articles where Stope is discussed: mining: Underground mining: of extracting ore are called stopes or rooms. There are two steps involved in stoping. The first is development—that is, preparing the ore blocks for mining—and the second is production, or stoping, itself. Ore development is generally much more expensive on a perton basis than stoping, so that every effort

The least common method in hardrock mining, block caving, is typically saved for lowgrade ore. It involves drilling a section of ore at the very bottom of the deposit and then blasting to make the roof collapse. Gravity then takes over, as the ore above the blast site fractures and collapses in succession as support is withdrawn.

Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the
