The environmental toll of underground mining is significant. It includes air pollution, changes in waterflow patterns, chemical and gas seepage into water supplies and soil, inaccessible fires in abandoned mines, and dramatic changes in land composition that can make the area unusable after the mining operation is done [source: Saxena]. Then there is the human toll.
Topic Progress: ← Back to Lesson How do you scale the right way?

Case Study #8, Part 1: Underground Mine Mapping Procedure Application. Underground mine mapping requires the entry of traverse notes (for the placement of spads), entry of left and right offsets for locating mine pillars and perimeters, connecting the pillars and perimeters, the placing of special mine symbols and strata thickness measurements, and the drafting of projections for future mining.
Text mining is similar to data mining, except that data mining tools [2] are designed to handle structured data from databases, but text mining can also work with unstructured or semistructured data sets such as emails, text documents and HTML files etc. As a result, text mining is a far better solution.

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.
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.
1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately.
