Abstract
Abstract There is disclosed a mobile sludge handling apparatus which comprises first, second and third vehicles (2, 3, 4) which are coupled together to form a composite mobile unit. The first vehicle (2) carries a sludge-pump unit (5), and the second vehicle (3) carries a filter unit (6) which is arranged to receive sludge pumped thereto from the first vehicle (2) and to separate-out solid material from the sludge. The third vehicle (4) carries a conveyor unit (7) which is arranged to receive separated-out solid material from the second vehicle (3) and to convey such material to a discharge point for the apparatus. The apparatus is particularly suitable for use as an underground device for draining mining sludge, in which sludges or slurries of liquid and solid material underground can be processed on the first and second vehicles (2, 3), and only the solid residue is conveyed by the conveyor unit (7) on the third vehicle (4) to be collected in tubs (38) which are then transported to the surface for subsequent discharge of the solid material.
