EBZ160M-2H Bolter Miner
The EBZ160M-2H bolter miner is a medium-duty integrated machine for tunneling and anchoring operations. It integrates roadway cutting, material conveying and bolt support in one unit, eliminating repeated equipment relocation on site for medium-sized coal mine construction. Equipped with a 550 mm telescopic cutting unit and dual bolting units, it realizes parallel excavation and support.

Integrated Tunneling & Bolting for Higher Efficiency
Two bolt drills are mounted on one machine to complete excavation and anchoring simultaneously. The support height ranges 3.0–4.45 m, support width 4.0–5.5 m with a supported area of 4.2 ㎡. It cuts idle waiting time caused by separate tunneling and bolting equipment, greatly shortening roadway forming cycles.
Dual-gear Power for Versatile Geological Adaptation
The dual-setting cutting motor (160 kW /100 kW) works with two rotating speeds (48 r/min, 24 r/min) and a 550 mm telescopic stroke. It cuts rock up to 70 MPa uniaxial compressive strength and delivers cost-effective performance at 50 MPa, adapting well to both soft and medium-hard strata.
Reliable Mobility on Complex Underground Terrain
With total weight of 61 t and 2.52 m track width, the 0.16 MPa ground pressure reduces sinking risk. ±18° climbing capacity handles undulating tunnels. The 3.2 m wide shovel plate efficiently collects muck and prevents material accumulation.
Professional Bolting Performance for Safer Roadways
Each rock bolt drill provides 300 N·m torque at 500 rpm and 30 KN supporting force per anchoring point. Firm reinforcement stabilizes surrounding rock and lowers collapse hazards to meet strict mine safety requirements.
Convenient Delivery & Global Power Compatibility
The heaviest single non-detachable component weighs only 5.8 tons for easy split transportation and underground assembly. Dual-voltage input (AC1140 V / 660 V) matches worldwide mine power standards. The 110 kW oil pump motor coordinates perfectly with the cutting system for stable long-shift continuous operation.
