A ground control inspection is a documented, in-person examination of on-site terrain formations and locations that slope into working areas at a mine. As part of an ongoing ground control plan, these inspections help establish and reinforce prudent engineering design, reduce ground instability, and contribute to safer working conditions for miners and others on-site. This course covers the definition and purpose of a ground control inspection and includes examples of ground instability hazards, the definition of “angle of repose,” descriptions and examples of slope failures, and common ground control corrective actions.
