Field Evaluation of Hydraulic Backfill Compaction at the Lucky Friday Mine, Mullan, Idaho
The Bureau of Mines instrumented two similarly backfilled stopes--one filled in the normal manner and the other with the fill densified using vibratory compactors--to evaluate the effect of fill compaction on subsequent vein-wall closure proposed as a adjunct porcess for strengthening cemented fill. Hydraulic pressure cells to monitor pressures within the fill and mechanical closure devices to measure vein-wall movement and the procedure for their installation are described. The field compaction work was generally performed manually by utilizing small commercial concrete vibrators. A prototype immersible vibrator using slusher cables to propel the vibrator in the stope was used on several lifts of fill. (Author)
