Methods that allow the knowledge extraction from data, while preserving privacy, are known as privacy-preserving data mining (PPDM) techniques. This stone surveys the most relevant PPDM techniques from the literature and the metrics used to evaluate such techniques and presents typical applications of PPDM methods in relevant fields.
Coal Mining Methods - Colorado School of Mines
Longwall mining and room-and-pillar mining are the two basic methods of mining coal underground, with room-and-pillar being the traditional method in the United States. Both methods are well suited to extracting the relatively flat coalbeds (or coal seams) typical of the United States. Although widely used in other countries, longwall mining ...
