Jan 27, 2014· Undergrounds mining is still, even after hundreds of years of safety improvements, a dangerous and expensive business. It''s wise for an investor to understand both the basic workings for an underground mine and the risks associated with underground mining.
There are four main mining methods: underground, open surface (pit), placer, and insitu mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments. Insitu mining ...
Gold mining is the process of mining of gold or gold ores from the ground. There are several techniques and processes by which gold may be extracted from the earth. Placer mining Placer mining is the technique by which gold that has accumulated in a placer deposit is extracted.
The method to be used for underground mining depends on the concentration of ore, strength of the surrounding rock, and the various risks involved. ScienceStruck explains what these methods are, with the applications of each one.
There are hardrock underground mines, and there are softrock underground mines. Coal deposits, for instance, live in relatively soft sedimentary rock. Gold deposits live in igneous or metamorphic rock, which is relatively hard, as do diamonds, copper, silver, nickel and zinc [source: Great Mining].
"Everything in underground mining is a compromise between what looks good on paper and what an orebody will allow one to do" Transverse Longhole Stoping is a popular large scale underground mining method known for its ability to simplify stope sequencing.

The once primitive, cumbersome mining methods used during that time has developed into compact, efficient modernday equipment that makes gold mining a more costeffective, efficient process. Likewise, the mining equipment used today helps reduce waste and chemical exposure throughout the various phases of gold mining. The Basics of Gold Mining ...
Underground mining (hard rock) Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals such as those containing metals like gold, copper, zinc, nickel and lead or gems such as diamonds. In contrast soft rock mining refers to excavation of softer minerals such as coal, or oil sands. Mine Access
Other gold mines use underground mining, where the ore is extracted through tunnels or shafts. South Africa has the world''s deepest hard rock gold mine up to 3,900 metres (12,800 ft) underground. At such depths, the heat is unbearable for humans, and air conditioning is required for the safety of the workers.
Open pit mining is conducted by the contractor Gounkoto Mining Services (GMS), a local subsidiary of DTP Terrassement, using either freedig or conventional drill, blast, load, and haul methods. The Yalea and Gara underground mines are currently operating .
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.
