The more and more expressive need for metal ores, especially for lead and zinc, bring to an increase in productivity in current mines. However, as for economic parameters even though there are prerequisites for a rentable exploitation, the application of widespread breaking methods is not always possible for technical, safety and ecological reason. Therefore methods of back-filling the cavities are more and more frequent. For that purpose, in considerable number of cases, the existing tailings (mining and flotation) in the proximity of the mine is used. This Paper presents parameters of preparation and transport of the tailings in the form of paste to the face, on the example of the lead and zinc mine SASA. |
