Advance and Relieve Mining: A Method to Mitigate the Affects of High Horizontal Stress on the Mine Roof

摘要

Evaluation of the 'Advance and Relieve' mining method is described to determine effectiveness for conditions where high horizontal stresses caused long running roof falls resulting in hazardous conditions and the premature abandonment of panels. 'Advance and Relieve' mining involves the removal of a pillar of a portion of a pillar during development, creating a cave along one side of the panel.
