AO-H02 — DRILLING WITNESS HOLD & MINE RETURN-TO-SERVICE GATE
AO-H02 is the source-original five-gate witnessed hold and mine return-to-service form for service drilling, anchor drilling and small non-production penetrations. Its first gate is rock-engineer approval of exact bore geometry, followed by service detection and geological risk checks.
WHERE AND WHEN TO USE THIS MINE RECORD
Use it before the mine accepts a critical drilling phase or returns an opened zone to operation. Complete MINE / AREA / LEVEL, WORK ORDER / MINE ZONE, DATE / SHIFT / PERMIT and CONTRACTOR SUPERVISOR, citing the current rock-engineering instruction and affected work area.
FIVE ACTUAL OPERATOR-OWNED WITNESS HOLD GATES
1. Rock engineering authorises exact location, depth and orientation
2. Service drawings and available scans checked for buried and overhead services
3. Old workings, unexpected voids and groundwater pressure examined before penetration
4. Ground support, shotcrete, mesh and pillar loads protected
5. Dust/water/gas suppression and respiratory controls appropriate to geology
HOW TO COMPLETE THE REAL WORD SOURCE
In five genuine HOLD TRIGGER / EVIDENCE GATE, REQUIRED EVIDENCE / VERIFICATION and RESULT / REFERENCE / WITNESS cells, capture engineer-authorised position/depth/orientation, scans for services, old working/void/groundwater reviews, preserved mesh/shotcrete/pillars and geology-appropriate dust, gas and respiratory protection.
IMPORTANT SAFETY AND AUTHORISATION RESTRICTIONS
All applicable holds must PASS, evidence must trace to the approved mine work order and defect corrections must be witnessed. Operator-owned release is by named mine authority only; the contractor's signed record is not work or occupancy permission.
SOURCE EVIDENCE AND RESPONSIBLE REVIEW
The source provides operator-owned RELEASE CONDITION, witnessed correction and mine supervisor/host signatures where required and Date / release reference.
