Underground Mining Methods — New Pacific Metals

In 2005, only 17% of metal mines were underground operations (Raw Materials Data, Stockholm 2010) – but there are many instances where underground extraction of minerals is more cost-effective than surface mining, typically when the given ore body is high grade or very deep. Due to the smaller nature of underground operations, they typically have much lower production rates than surface ...

Types of Underground Mining Method Comparison

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.

Mining - Underground mining | Britannica

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 …

However,the oldest known underground mine,a hematite mine at Bomvu Ridge,Swaziland(Gregory,1980),is from the Old Stone Age and believed to be about 40,000 years old. Early miners employed crude methods of ground control,ventilation,haulage,hoisting, lighting,and rock breakage. Nonetheless,mines attained depths of …

Two of the ways that they mine underground are: Room and pillar mining: there are intersecting rooms with pillars of coal thathold up the roof. These pillars are mined when the mine, or a part of it, areclosing. They are careful when they do this because the roof caves in as theyleave. Longwall mining: usually a machine called a continuous miner slices layers ofcoal or minerals from the walls.

Mining - Wikipedia

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

Guidance about underground air quality and ventilation

Ventilation in an underground mine is of critical importance to the occupational health and safety of underground employees. The atmosphere underground is limited and confined, and is thus readily reduced to a sub-standard (or even dangerous) condition if contaminants (e.g. gases, dusts, fumes) produced in the course of operations are not controlled, safely extracted or diluted to acceptable ...
