AO-TT03 — DRILLING SHIFT CHANGE & WORKFACE LESSONS TOOLBOX TALK
The source-original AO-TT03 shift-change and workface lessons toolbox talk for mine drilling, coring and non-production openings starts with rock-engineer approval of exact drilling position, depth and orientation. It prevents new crews from relying on outdated permits or assumed safe openings.
WHERE THIS SPECIFIC UNDERGROUND RECORD APPLIES
Use it at handover between service-drilling crews or after an unexpected support, service or geological condition. Record MINE / AREA / DATE / SHIFT and PERMIT / PRESENTER and reference the real mine rock-engineering instruction, service plan and underground zone.
SIX ORIGINAL WORKFACE BRIEFING CONTROLS
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
6. Drilling machine anchorage, guarding and rotating steel risks controlled
HOW TO COMPLETE THE GENUINE SOURCE WORD FORM
Discuss six actual source controls: engineer-approved bore geometry, available service drawings/scans, old workings and groundwater pressure, protection of support/mesh/pillars, geology-appropriate dust/water/gas protection, and machine anchorage/rotating steel safeguards. Fill in the genuine 16 attendance lines.
DRILLING STOP RULE AND MINE AUTHORITY
The source says STOP / WITHDRAW / NOTIFY MINE CONTROL when water or gas appears unexpectedly, support is intersected or a penetration lacks approval. Restart only on the mine-appointed official's release; a shift change does not reset the hazard.
REAL-LIFE EVIDENCE AND COMPETENT APPROVAL
Keep the mine risk assessment, permit and support drawings with the talk; a signature does not authorise work.
