hydraulic filling
Washing waste material, such as mill tailings and ground waste rock, into stopes with water to prevent failure of rock walls and subsidence. Problems involved in its use are stope preparation, choice and mixing of material, its particle size distribution, wear on 1553 pipe, and removal of water that transports the material into the mine. Compressed air may be used to force the filling through pipes.
