Heavy Tunneling Drill Equipment (for 7 × 6 m tunnel)
Hydraulic Underground Drilling Jumbo Rig
A full-size underground drilling jumbo with diesel/hydraulic power - this type is appropriate for tunnel rock drilling (blast holes, bolt holes) in large sections. Typical characteristics of jumbo rigs for tunnel drilling:
Designed for underground tunnel cross-sections like yours (≈42 m²)
Hydraulic rock drilling systems for high drilling speed
Multi-boom options possible (1–3 booms)
Used for drilling face holes prior to blasting in hard rock If you want, I can help you estimate power/size specifications (like boom length, engine kW, drill diameter) based on your geological conditions and production goals - just let me know your rock type and tunneling method (drill-&-blast vs continuous).
