Impact
Tracked support loads during excavation and documented the unloading and removal of accessible monitoring equipment.
Challenge
The development excavation required strain tracking and load calculations for raker supports R9–R12.
STRAAM approach
STRAAM tracked strain in four rakers and applied a thermal correction of 1 microstrain per °C.
Result
At closeout, monitored supports were unloaded and accessible equipment was removed as excavation advanced.
