Ground Control Stability Assessment Checklist [FREE PDF]

Ground control stability assessments are mandated under MSHA 30 CFR Part 57.3200-57.3461 for underground metal and nonmetal mines, requiring systematic evaluation of roof, ribs, and floor conditions before each shift. Failure to conduct thorough ground control inspections is among the leading causes of fatalities in underground mining operations. This checklist provides a structured framework for identifying hazardous ground conditions, scaling requirements, and support system integrity in compl

  • Frequency: Daily
  • Estimated Time: 30-45 minutes
  • Role: Mine Safety Manager
  • Total Items: 33
  • Compliance: MSHA 30 CFR Part 57.3200 - Ground Support, MSHA 30 CFR Part 57.3360 - Examination of Ground Conditions, MSHA 30 CFR Part 57.3461 - Working in Unsupported Areas, MSHA 30 CFR Part 56.3200 - Surface Mine Ground Control, State Mining Regulations - Ground Control Plan Requirements

Pre-Entry Ground Condition Assessment

Evaluate overall ground stability and hazard indicators before allowing worker entry into the area.

  • Has a competent person examined the area for ground hazards within 8 hours prior to entry?
  • Are visible indicators of ground movement (cracks, spalling, or deformation) absent from roof and ribs?
  • Has the area been sounded (barred down) for loose material prior to worker entry?
  • Are all identified ground hazards from previous inspections recorded and addressed?
  • Has the current ground control plan been reviewed and is it accessible on site?

Roof and Back Condition Inspection

Systematically inspect overhead ground conditions including rock quality, support integrity, and hazardous features.

  • Is the roof or back free from loose rock, slabs, or overhanging material?
  • Are rock bolt installations within the inspection area meeting the approved ground control plan specifications?
  • Are visible roof cracks or joints oriented in a direction that could cause falls?
  • What is the estimated span of unsupported roof in the widest section (in feet)?
  • Are wire mesh, screen, or shotcrete panels intact and free of tears, buckling, or separation?

Rib and Pillar Condition Assessment

Inspect side walls, ribs, and pillars for signs of stress, failure, or instability.

  • Are mine ribs free from loose or sloughing material that could injure workers?
  • Are pillars showing signs of excessive cracking, spalling, or hour-glass deformation?
  • Are rib bolts or rib support systems installed per the ground control plan and in good condition?
  • Is the minimum rib-to-rib clearance maintained per the approved mine plan?
  • Are any rib control measures (shotcrete, bolting, scaling) required based on current observations?

Floor Conditions and Drainage

Assess floor stability, heave potential, water accumulation, and sump conditions.

  • Is the floor free from heave, swelling, or uplift that could indicate stress redistribution?
  • Is accumulated water present on the mine floor in the inspection area?
  • Are drainage channels and sumps clear of debris and functioning properly?
  • Are soft or unstable floor areas marked and barricaded to prevent worker exposure?

Ground Support Systems Integrity

Evaluate installed ground support hardware including bolts, cables, sets, and monitoring devices.

  • Are all installed rock bolts torque-tested and confirmed to meet minimum load specifications?
  • Are cable bolts, split sets, or other secondary support systems free from visible damage or excessive deflection?
  • Are ground movement monitoring instruments (extensometers, tape extensometers, prisms) in place and recording?
  • Have monitoring readings been compared to trigger action response levels (TARLs) and found within acceptable limits?
  • Are timber sets, steel arches, or structural supports free from rot, corrosion, or mechanical damage?

Post-Blast Ground Disturbance Assessment

Assess the impact of recent blasting operations on surrounding ground stability.

  • Has the area been re-examined for ground hazards following any blasting operations in the last 24 hours?
  • Are new cracks or fractures observed in the roof, ribs, or pillars following blasting activities?
  • Has all loose material dislodged by blast concussion been scaled from overhead and ribs?
  • Are previously installed support systems undamaged and unaffected by blast vibration in the inspection zone?

Hazard Communication and Corrective Actions

Document identified hazards, corrective actions taken, and communication to affected personnel.

  • Have all ground hazards identified during this inspection been communicated to the shift foreman and affected miners?
  • Have areas with uncontrolled ground hazards been barricaded and posted to prevent unauthorized entry?
  • Have all corrective actions initiated during this inspection been documented with responsible parties and target completion times?
  • Describe any ground hazards identified and corrective actions taken or scheduled:
  • Is this inspection record being retained on site for the required minimum period?
