AH-H02 — DEWATERING WITNESS HOLD & MINE RETURN-TO-SERVICE GATE
Five genuine independent mine water-system witness holds covering critical dewatering isolation, emergency flood routes, contamination, cross-connections/backflow and trapped-pressure check valves.
ORIGINAL MINE WATER SYSTEM WORK SCOPE
Use at formal mine-owned release points before or after pump, sump and pipeline works. Complete MINE / AREA / LEVEL, WORK ORDER / MINE ZONE, DATE / SHIFT / PERMIT and CONTRACTOR SUPERVISOR; name the mine water official.
FIVE INDEPENDENT MINE OWNER WITNESS GATES
1. Approved pump and line isolation maintains critical mine dewatering capacity
2. Emergency flood route, escape levels and water-rise trigger agreed with operator
3. Potential contamination, sediment and acid water exposure assessed
4. Uncontrolled cross-connections and backflow prevented in temporary hose arrangements
5. Pressure release and non-return valves inspected before line-breaking
FILLING THE REAL PRINTED WORD SOURCE FIELDS
Fill original HOLD TRIGGER / EVIDENCE GATE, REQUIRED EVIDENCE / VERIFICATION and RESULT / REFERENCE / WITNESS columns. Include true duty/standby pumping data, water-rise/escape plans, contamination control and pressure release.
MINE DEWATERING STOP-WORK AND RELEASE
The printed RELEASE CONDITION requires all applicable holds PASS with work-order traceability, corrected defects and witness acceptance. Only authorised mine officials approve plant and working-area release.
TECHNICAL EVIDENCE AND MINE SAFETY RESPONSIBILITY
Maintain current upstream inflow measurements, water level logs, accepted standby pumping, witnessed pressure/pipe tests, electrical immersion controls, flood refuge and evacuation information. This genuine editable Word is a contractor evidence form; it cannot replace mine water engineering, isolation or plant restart permission.
