Properties of hydraulic backfills and preliminary vibratory compaction tests
In-place density of hydraulic backfills affects properties of strength, consolidation, and water percolation; dense fills give better support than loose fills; in-place density properties themselves are affected by grain size, grain size distribution, and particular conditions of sedimentation in stope; field sampling of in-place densities of fills used in 4 different mines and laboratory and underground compaction tests using standard concrete vibrator show that initial in-place density of cohesionless fill material tested can be significantly increased by vibratory compaction.
