Abstract
Roof, pillar, and floor instability have long influenced mine safety, ventilation, productivity, and resource recovery. Based on decades of meansurements in ten U.S. mines, suitable measurement techniques and preliminary stability evaluation criteria are proposed for prudent structural stability assessments. Three methods that use the changes in rock deformation, fracturing, and stress conditions are shown to be useful and effective for routine stability evaluations and show potential for improving safety in underground excavations.
