What are examples of unsupported mining methods?
One example of an unsupported mining method is Room-and-Pillar mining. This method involves timber beam supports to hold up the cave in which the mining is taking place. Another example involves using the mineral, such as coal, to hold up the walls. Pillars of the mineral are left in the mine as supports. This method allows for less of the mineral to be collected, because it is being used for the actual support of the mine. Correction Simply put, unsupported mining refers to the use of the grounds natural rock strength and the principals of ground control techniques to extract ore (with some waste) from the ground. There are two types of mining, surface and underground. The term support generally refers to the application of timbers, concrete, shotcrete, rock bolts, rock cables, screens, etc and a combination of these. Unsupported mining on surface is carried out successfully by designing pits with slopes that are at such an angle that the walls will not collapse during the extraction process. The ideal slopes have safety factors that are greater than 1.0. The ideal open pit mine would be one that would stand in place until all the economic material was removed, after which failing or slumping. Unsupported mining under the ground (u/g) is carried out successfully by designing openings either drifts, cross cuts, stopes, raises and other that are of the size and shape that they do not fail or "cave". Generally hard, competent rock that is not highly fractured, faulted, or jointed will lend itself to unsupported mining techniques u/g. Rocks that can be mined with the use of ground controlling tools or devices can generally be mined by a few different methods, room and pillar, longwall stoping, sublevel stoping, and block caving.

What is overhand and underhand mining?
Overhand cut and fill mining involves excavating a horizontal slice of an orebody, then filling the void with a backfill material - typically mine waste or rejects from the processing plant . After backfilling, another slide is taken on top of the previous one, with the process proceeding until the orebody extraction is complete. Underhand cut and fill mining also starts with a single horizontal slice, but subsequent slices are removed from below the initial one. In underhand mining, the backfill material usually has cement added to make a low grade concrete roof that is sufficiently strong to safely work under.

What is artisanal gold mining?
An artisanal or small-scale miner is, in effect, a subsistence miner, who often undertakes the activity of mining gold seasonally - for example crops are planted in the rainy season, and mining is pursued in the dry season. They are not officially employed by a mining company, but rather work independently, mining or panning for gold using their own resources. They tend to use primitive methods of mining, including the use of very toxic mercury to extact gold.
