Backfill material or building materials for use underground
During the extraction of raw materials, cavities are created underground. Depending on the use, these must be stabilized if the route is still used for access to the mining area. For this purpose, mixing plants and pumps are used underground to produce and pump concrete. The plants are supplied with the required materials by pneumatic conveyance and are delivered through a pipeline laid in the shaft or in a borehole. Tailings can also be pneumatically conveyed underground as backfill material. Depending on the type of backfill, this dry material is either placed directly or processed further underground for flushing backfill.
