Extracting narrow underground veins (<3m wide) faces equipment limitations: Traditional tracked excavators are bulky (turning radius >3m) with slow hydraulics, causing "tunnel jams." Drill jumbos lack flexibility despite high power, costing >$1M and requiring specialized operators. When tunnel roof supports are <1.8m apart, traditional equipment fails entirely, forcing segmented blasting that slashes efficiency by 50%.
Revolutionary Breakthrough of Narrow Vein Mining Excavator:
Ultimate Space Adaptability: Models like HWL75S narrow vein mining excavator (1.75m width, ≤6.8m turning radius) pivot 360° in 2.2m tunnels via articulated chassis.
Multi-Condition Handling: Standard side-dump bucket/gooseneck boom enables 90° vertical digging without repositioning.
All-Terrain Mobility: 4-wheel suspension + 180mm ground clearance crosses rubble/water obstacles.
Field Test: Peru Copper Mine Tunnel Project
With 2.2m tunnel width and 1.7m roof supports, traditional equipment was unusable. After deploying HWL75S narrow vein mining excavator:
lDaily output surged from 80 to 180 tons (+125%)
lFuel consumption: 3.2L/hour (40% less than traditional gear)
lDiesel/electric dual-mode avoided ventilation limits
Project lead: "Like custom-made for narrow tunnels—zero jams, 10-minute attachment swaps (breaker/drill)."
Global mining’s "narrow-tunnel efficiency revolution" is here. The narrow vein mining excavator dominates corner-ore recovery and residual mining with its mobility, adaptability, and quick-change efficiency.
