Safe Handling Procedure for Overburden (O.B.) Dump

Essential safety guidelines for dumping overburden in opencast mining operations to prevent accidents, dump failures, and ensure compliance with safety standards.

1. The overburden (O.B.) shall be dumped at a distance of 3.5 m from the edge of the O.B. dump and the dozer shall push the same O.B.
2. Operators shall not drive their vehicles into the non-operational area designated by a berm of minimum height 1.5 m.
3. Operators shall not drive on unstable surfaces or near marked danger zones.
4. The operator shall visually inspect the area before reversing the dumper/tipper.
5. Where no berm exists, dumping shall be done before the edge and monitored by Mining Sirdar.
6. A safety berm of minimum 1.5 m height and 2 m width shall be prepared by dozer.
7. Dumper/tipper shall stand straight behind the berm.
8. Operators must maintain visual contact during reversing.
9. Hoist operation only when stationary and remain inside cabin.
10. Unsafe situations must be reported immediately.
11. Speed limits: 10 km/hr forward and 5 km/hr reversing.
12. Use AVA (Audio Visual Alarm) while reversing.
13. Dump should slope upward for drainage.
14. No unauthorized entry allowed.
15. Post-rain joint inspection mandatory.

Key Safety Reminders (DGMS & Best Practices Alignment):

Always maintain safety berms, inspect dump edges for cracks/soft areas after rain, follow designated dumping procedures, and ensure no dumping over edges without supervision. These steps help prevent tip-over incidents, slope failures, and ensure safe overburden management in opencast mines.

Follow these procedures strictly for zero-harm operations.
