Ore Pass

Ore Pass

 · Ore pass is a vertical or nearvertical opening created during underground mining operation to transfer materials. It is designed based on the gravitational force between different ground levels to provide convenient material handling system and reduce haulage distances.

Sampling practice and theory

 · Sampling is defined as taking a small portion of a whole mass that accurately represents the whole mass. Very simple to define, however obtaining a representative sample is anything but simple. Mathematicians will say sampling is expressible as a series of mathematical equations. Such as, for sampling "X" pounds of material, one would take "y ...

Underground Ramp Design Parameters

Underground Ramp Design Parameters

When establishing a mine plant design, of which ramps are a vital component, it is important to consider how equipment and ore will be able to move throughout the mine efficiently. Some large mines with multiple orebodies may need more than one surface production ramp.

Mining is the process of extracting useful materials from the earth. Some examples of substances that are mined include coal, gold, or iron ore is the material from which the metal iron is produced. The process of mining dates back to prehistoric times. Prehistoric people first mined flint, which was ideal for tools and weapons since it breaks into shards with sharp edges.

Underground hardrock mining

Underground hardrock mining

Underground hardrock mining refers to various underground mining techniques used to excavate "hard" minerals, usually those containing metals, such as ore containing gold, silver, iron, copper, zinc, nickel, tin, and also involves the same techniques used to excavate ores of gems, such as diamonds and rubies. Softrock mining refers to the excavation of softer minerals, such as salt ...

Stoping

Stoping

Stoping is the process of extracting the desired ore or other mineral from an underground mine, leaving behind an open space known as a stope. Stoping is used when the country rock is sufficiently strong not to collapse into the stope, although in most cases artificial support is also provided.. The earliest forms of stoping were conducted with hand tools or by firesetting; later gunpowder ...
