Mine backfill – an overview - tu-freiberg.de

equipment (mixer, pumps, pipelines) are necessary. A potential other drawback might be, that hydraulic backfill brings additional water into the mine and construction of dams may be necessary to isolate the backfilled excavations and to avoid outflow. The properties of backfill are determined by the following parameters (Moser, 2016):
