Abstract
Observations of ground behavior in mining the Choka Dulkan ore body have been described. Ore recovery was limited to approximately 60% because unconsolidated hydraulic fill did not permit either the widening of stope spans nor secondary ore recovery from pillars. Stope undercutting induced high stress concentrations. However, as extraction progressed, ground conditions improved but before extraction was complete they deteriorated again. After completion of a stope, the remnant rib and crown pillars continued to be deformed by other stresses for some time.
