Backfilling/pastefilling represents more than just an efficient disposal method for waste tailings, in fact backfill is recognized as the most effective rock support system for mined-out large underground openings. However, the mechanical behavior of backfill once placed is relatively poorly understood. YieldPoint provides and is developing innovative solutions that can monitor the following processes:
Delivery
system diagnostics: pressure in lines, flow rates etc
Monitoring
cure process using low cost Thermostrings
Mechanical
deformation and pressure profiles in fill using proprietary
“distributed” YieldPoint pressure sensor technology
Monitoring
sag and angular rotations of fill in situations involving mining under
fill
Innovative solutions for fill mat monitoring designed to accurately
measure flexural and rotational failures
