Roof Bolt Installation and Integrity

Inspect primary roof support per 30 CFR 75.202 and approved ground control plan.

Are roof bolts installed at spacing and pattern specified in approved ground control plan?
Are mechanically anchored bolts torque-tested to minimum 100 ft-lb per 30 CFR 75.202 requirements?
Are bearing plates fully seated against roof with no gap indicating inadequate anchorage?
Are resin-grouted bolts installed with correct resin type and rotation time per manufacturer specification?
Are there any missing or un-tensioned roof bolts from previous shift that require immediate attention?
Have pull-out tests been conducted per frequency in approved ground control plan?

Secondary and Standing Support

Inspect supplemental support in high-stress or poor ground areas.

Are all cribs, props, and standing support installed per ground control plan requirements?
Are timber sets, steel arches, or shotcrete liners in good condition with no cracking or buckling?
Are ribs in adequately supported condition with rib bolts or mesh preventing rib sloughage?
Is unsupported span in any location within approved maximum unsupported span from plan?
Has loose or hazardous roof and rib material been scaled prior to start of work?

Roof Movement Monitoring

Monitor ground control indicators per approved plan.

Are roof monitoring telltales or extensometers installed and readings within alert levels?
Is pillar and entry convergence within acceptable range per monitoring plan?
Is geotechnical mapping of roof conditions current with geological hazards identified?
Have geologically incompetent zones (faults, slickensides, dykes) been identified and marked on mine map?
Is microseismic monitoring system operational and data reviewed daily in seismically active mines?

Pillar Design and Highwall Stability

Verify pillar safety factors and highwall conditions per approved mining plan.

Do pillar dimensions conform to approved mining plan providing minimum safety factor of 1.5?
Are pillars free of excessive spalling, slabbing, or hourglass conditions indicating overstress?
Are surface highwalls maintained at stable slope angles per geotechnical design?
Are safety berms at crest of all highwalls at least wheel-height of largest equipment per 30 CFR 56.3401?
Has a competent person inspected the highwall at beginning of each shift before work begins?
