Top Tasks Performed by WPE-7.5/24
Flitching Operations
Definition: Flitching is the removal of loose rock or coal layers from roadway walls and floors.
Why It Matters:
- Prevents roof or wall collapses by removing unstable rock.
- Creates safer pathways for workers and machinery.
- Prepares tunnels for subsequent mining or maintenance operations.
Best Practices:
- Inspect the target area for hidden cracks before flitching.
- Adjust hydraulic pressure for controlled debris removal.
Floor Dinting
Definition: Floor dinting involves leveling the mine floor for safe equipment and personnel movement.
Advantages:
- Reduces wear and tear on mining machinery.
- Improves operational efficiency by providing smooth travel paths.
- Minimizes tripping hazards and promotes safe underground access.
Operational Tips:
- Use the machine’s 360° arm rotation for comprehensive coverage.
- Maintain consistent pressure and bucket angle to ensure even floor leveling.
Anchor Cable and Bolt Cutting
Definition: Precision cutting of anchor cables or bolts used for mine reinforcement.
Why It Matters:
- Enables quick adjustments to support systems.
- Reduces downtime compared to manual cutting methods.
- Prevents over-stressing surrounding rock or support structures.
Technical Insight:
- The WPE-7.5/24’s attachments are designed for precise alignment with bolts.
- Cushioning on hydraulic cylinders ensures smooth cutting without shock loads.
