238 / AO-C01 — PRODUCTION DRILL PRE-START AND MINE INTERFACE CHECKLIST
AO-C01 is the original editable seven-point Word pre-start and mine operating-interface checklist for surface-mine production rigs, survey drill patterns and charged-hole exclusion boundaries. It begins with the authorised survey pattern and geotechnical pad release before checking equipment and exposure safeguards.
WHY THIS DRILL WORKFACE CONTROL MATTERS
A contractor can mobilise a drill rig before confirming its pad or hole map matches the current mine-approved pattern. Mast stability, crest setbacks, silica extraction, protected collars and mine-owned charged-hole buffers require documented pre-start checks; lightning and misfire suspicion override a completed production plan.
SEVEN SOURCE-DEFINED WORKFACE VERIFICATIONS
1. Approved survey pattern/geotechnical pad release show authorised hole locations, burden and edge limits. 2. Drill-rig levelling, isolation, mast stability and manufacturer setup validated. 3. Highwall crest setback and mine flyrock/explosives exclusion briefed to drill crew. 4. Dust extraction and silica respiratory protection maintained at production rig.
5. Hole collar protection, depth, deviation and water ingress documented for blast team. 6. Charged holes and exclusion buffers marked under mine blasting authority control. 7. Storm/lightning, misfire suspicion and blast notification included in STOP criteria.
REAL SOURCE FIELDS, DEFECTS AND MINE RELEASE
Seven actual source questions use Y, N, N/A and EVIDENCE / DEFECT / ACTION, with MINE / PIT / WORK AREA and WORK ORDER / MINE ZONE fields. The first row is approved survey/pad release, the last storm and misfire STOP triggers. This is not an autonomous drilling permit.
Any NO, N/A or changed condition requires evidence and justified action. The printed HOLD stops work for missing clearance, isolation, protection or critical evidence.
Complete MINE / PIT / WORK AREA, WORK ORDER / MINE ZONE, DATE / SHIFT / PERMIT and CONTRACTOR SUPERVISOR. Contractor and MINE RELEASE AUTHORITY / SIGNATURE with DATE / RELEASE REF are separate; no self-approved drilling or blasting permission.
