Recommended packages
Air compressor match
Underground jumbos run on the mine's electric/hydraulic supply — confirm voltage and water/air services at the heading. Where air is needed, match a KSDY electric compressor to the site power.
DTH hammer & bits
Kaishan underground rigs use premium hydraulic rock drills (Montabert HC50/HC95/HC109) for face and production drilling; the KSQ31 DTH model runs K-class hammers. Confirm rock drill model against your tunnel section.
