THE ACTUAL MINE ELECTRICAL HAZARD
An undocumented UPS or PV backfeed, inhibited trip or lost protection could leave an apparently isolated mine control circuit dangerous to touch and cause loss of dewatering, collision avoidance or fire detection. This original teaches crews to recognise failure and insist on a documented mine technical release.
ORIGINAL DOCUMENT CONTROLS — PRINTED SOURCE ORDER
1. Include generator, UPS, capacitor, PV and automatic-restart or backfeed sources in the isolation schedule.
2. Assess mine dispatch, collision avoidance, dewatering and fire-detection dependencies before intervention.
3. Authorise instrument ranges, trip setpoints and alarm inhibits with restoration time and named custodian.
4. Record calibration standard identity, as-found and as-left values and test uncertainty.
5. Verify dust ingress, lightning, earthing continuity, cable routes and IP protection before energisation.
6. Have mine technical owner witness protection proof and authorise return to service.
EVIDENCE AND TRUE WORD DOCUMENT FIELDS
This is original AVC AD-TT04, a six-point electrical mine toolbox talk within Electrical, Instrumentation & Control Systems. Mine/area/date/shift and permit/presenter identifiers, six numbered briefing subjects, and precisely 16 NAME/EMPLOYEE OR ACCESS NO. and SIGNATURE attendance lines.
STOP-WORK, HOLD AND AUTHORITY
STOP, WITHDRAW, NOTIFY MINE CONTROL for unknown supply/backfeed, defeated trip or uncontrolled impairment of critical mine plant. The mine-authorised official, not the presenter, releases the zone/system.
PRACTICAL APPLICATION ON MINE WORKFACES
Use after a protection fault, unproven isolation, altered alarm bypass or change to a critical mine control system. Fill the editable Word DOCX with real equipment tags, permit IDs, test measurements and appropriate mine sign-off. An unanswered technical gate or blank result must remain open, not be converted into an accepted record.
