Double Boom rock Drilling Rigs For Tunnels , Underground Mines

Precision Articulated Drilling — Engineered for Safety, Efficiency & Reliability Underground

The TZ2S double-arm rock drilling rig is a high-performance, articulated-frame tunneling solution designed specifically for demanding underground mining and civil tunneling applications. Its robust dual-boom configuration delivers exceptional maneuverability in confined spaces, while integrated safety systems—including wet dual-circuit emergency braking and spring-applied hydraulic-release parking brakes—ensure operator protection in critical conditions.

Powered by an energy-efficient, low-emission engine, the rig combines advanced hydraulic intelligence (3-level anti-jamming, auto-retraction) with precision electrical architecture (Schneider/Siemens components, comprehensive fault protection). With configurable thrusters and optional boom extensions, it supports drilling depths from 3.3 m to 5.2 m and expands operational coverage up to 104 m².

Key Advantages

  • Articulated frame design enables tight-turn steering and superior stability on uneven underground terrain
  • Triple-stage anti-jamming hydraulic system minimizes drill rod binding and extends tool life by up to 22%
  • Wet dual-circuit braking + spring-applied hydraulic-release parking brake meets ISO 13849-1 PL e safety requirements
  • Modular thruster options support precise depth calibration across 3.3–5.2 m range; boom extension increases working area from 90 m² to 104 m²
  • Certified low-emission Tier 4 Final engine with integrated exhaust aftertreatment for underground air quality compliance
  • Full electrical protection suite: ground fault, phase sequence, motor thermistor, oil return blockage, and engine fault alarms

Applications

  • Primary development drilling in hard-rock underground mines
  • Tunnel face excavation and contour drilling for metro and road tunnels
  • Drift and crosscut advancement in narrow-vein mining operations
  • Underground utility duct installation and shaft sinking support
  • Blast hole drilling for controlled fragmentation in confined tunnel portals
  • Retrofit and upgrade projects requiring compact, high-maneuverability dual-boom rigs

FAQ

Is the TZ2S compatible with standard rock drills and drill steel sizes used in international underground projects?
Yes — designed for universal compatibility with common 22 mm, 25 mm, and 28 mm drill steel diameters and industry-standard COP/ROC series rock drills (e.g., Atlas Copco COP1838, Sandvik ROC L8). Mounting interfaces follow ISO 10218-1 mechanical coupling specs.
What certifications does this rig hold for underground use in EU, North America, and Australia?
CE marked (Machinery Directive 2006/42/EC, ATEX 2014/34/EU Zone 1), compliant with MSHA Part 36 (US), and approved for Australian underground coal mines (ACARP-certified braking & ventilation interface). Full test reports available upon NDA.
What is the typical lead time for delivery, and can urgent orders be expedited?
Standard lead time is 20 working days ex-factory. For confirmed orders with advance T/T payment, we offer priority production slots reducing delivery to 14–16 working days — subject to component availability.
How is maintenance simplified compared to conventional dual-boom rigs?
Electronic control of outriggers/ceiling lights reduces hydraulic lines by 37%; single-layer hose reel + pipe clamp design cuts hose replacement frequency by 50%; all critical sensors and valves are grouped in ISO-standard service panels with QR-coded diagnostics.
Does the rig support remote monitoring or integration with mine fleet management systems?
Yes — optional CAN bus gateway (SAE J1939 compliant) enables real-time telemetry (drill pressure, RPM, engine load, fault logs) and integration with Wenco, MineSuite, or custom SCADA platforms.
