Hydraulic Drilling Jumbo

Product Introduction

This fully‑hydraulic underground drilling jumbo is engineered for blasting hole drilling, rock‑bolt anchor hole drilling and cross‑cut opening work in underground metal mines, hydropower, highway and railway tunnels.

Available in compact single‑boom, standard single‑boom and heavy‑duty double‑boom configurations. The equipment features high‑performance rock drill unit, articulated wheel chassis and premium electrical components. Built‑in anti‑jamming drilling protection reduces drill‑rod and bit damage. Flexible multi‑angle boom movement achieves full‑face drilling coverage without blind zones in confined underground drifts.

It adapts rock hardness f=6‑16 and above. Multiple engine emission options support different regional import standards. Certification documents like CE, ISO, SGS are available. Customization for boom stroke, chassis and power package is supported for global mining and tunneling projects. Drilling speed reaches 0.8‑2 m/min, ideal for mid‑size underground working faces.

Application Scenarios

Underground Mining: Metal & non‑metal underground mines, blast hole drilling, rock‑bolt anchoring holes for mine support.
Tunnel Engineering: Hydropower diversion tunnels, highway tunnels, railway tunnels, cross‑cut opening operation.
Working‑face condition: Small‑medium cross‑section underground drifts with limited space.
Global market fit: Well‑suited for mining contractors in Africa, Latin America, Southeast Asia. For Australia and Canada, local safety & emission certifications must be completed before deployment, mainly targeting small‑scale private underground mining projects.
