Why ergonomics matters in mining
- Cuts musculoskeletal injuries (low-back pain, tendonitis, carpal tunnel).
- Boosts productivity and slashes absenteeism.
- Meets LOPCYMAT and Mining Safety Regulation requirements.
Top ergonomic risk factors
- Manual load handling without mechanical aids.
- Awkward postures in narrow drifts or drilling fronts.
- Whole-body vibration from drills and articulated trucks.
- Repetitive tasks in mineral sorting and bagging.
- Extreme heat & humidity that speed up muscle fatigue.
Recommended ergonomic practices
1. Work-station engineering
- Adjust conveyor height and sampling tables.
- Add swivel seats and adjustable platforms in cabs.
- Fit handles and lifting lugs on sacks and bins.
2. Mechanical aids & automation
- Hydraulic arms for loading heavy reagents and spares.
- Roller conveyors for tailings instead of manual carry.
- Pneumatic bolting systems that slash grip force.
3. Task rotation & active breaks
- Rotate crews every 2 h across crushing, lab and maintenance.
- Schedule micro-stretch pauses via video or company app.
4. Ergonomic PPE
- Certified lumbar support belts.
- Anti-vibration gloves with gel pads.
- Torsion-resistant boots for uneven ground.
5. Continuous training
- Workshops on proper lifting techniques.
- Hand‐signal training for hoisting.
- Monthly talks on fatigue management for night shifts.
Measured benefits
| Metric | 2022 | 2024 | Improvement |
|---|---|---|---|
| MS injuries/100 workers | 12.8 | 6.1 | -52 % |
| Lost-time days | 1 480 | 690 | -53 % |
| Productivity index (t/worker) | 1.95 | 2.40 | +23 % |
Mines running the ergonomic plan posted a 280 % ROI within 18 months.
Conclusion
Embedding ergonomics in Venezuelan mining protects workers, lifts morale and fattens profit margins. Investment in workstation redesign, mechanical aids and nonstop training is a win-win for companies and crews alike.
