Abstract:
Optimised geomechanical design of cemented paste backfill systems requires feedback on the actual field performance of paste fills and their barricades during filling, subsequent curing, and exposure to ongoing mining activities. A comprehensive monitoring strategy is described and its application is demonstrated for five stopes at three different mining operations. Important information is revealed about several poorly understood phenomena including stress arching within the fill mass, barricade pressure reduction with increasing setback from the stope, temperature induced stresses, and liquefaction potential of paste fill due to production blasting and rockbursts. Consideration is given to optimised monitoring procedures that other engineers could use to investigate similar phenomena at their mines.
