Underground mining – block caving, bore hole, drift fill,

Everything You Need To Know About Underground MiningUnderground mining (hard rock) - Wikipedia,Underground hard rock 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 lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies. Soft rock mining refers to excavation of softer minerals such as salt, coal, or oil sands. SUPPORT IN UNDERGROUND HARD ROCK MINES,The choice of the type of support installed in a particular underground excavation depends upon the extent of the zone of loosened or fractured rock surrounding that excavation. A very crude guide to support selection is given in Table 1. Active rock reinforcement Underground mines use two principal types of rock reinforcement - tensioned

Underground mining - SlideShare

10.04.2013· Underground mining is done when the rocks, minerals,or gemstones are too far underground to get out with surfacemining.Some kinds of underground mining are: Borehole Mining Drift Mining Hard Rock Mining Shaft Mining Slope Mining 3. Borehole MiningIt can be used in open pit mining which is a kind of surface mining.With borehole mining: a hole is drilled deep enough into theMining - Underground mining | Britannica,Once a decision has been made to go underground, the specific mining method selected depends on the size, shape, and orientation of the ore body, the grade of mineralization, the strength of the rock materials, and the depths involved. For example, if the ore is very high grade or carries a high price, then a higher cost method can be used. In order to minimize the mixing of ore and waste, highly selectiveUnderground Mining Transportation & Haulage Systems,01.04.2017· At 19 open-stope mines, transportation averaged 26.3 percent of the total underground cost; at 19 mines employing shrinkage stoping, 22.65 percent; at 3 mines employing block caving, 21.03 percent; at 8 mines employing square-set stoping, 12.77 percent; and at 4 mines employing cut-and-fill stoping, 12.9 percent.

Types of Underground Mining Method Comparison

16.03.2017· In any discussion of Methods of Underground Mining Comparison, one is repeatedly confronted with the difficulty of dealing with so many variable conditions. It is not an exact science and in the choice of a method each varying factor has a certain weight, which, in many cases, experience alone can determine. In mathematical terms, it is a function of many variables.

Differences between underground mining and open pit

What is underground mining. When the minerals are found in rich veins but in large volumes of sterile rocks, the only way to mine them is the underground mining method.
