EBZ200M-2H Bolter Miner
The EBZ200M‑2H bolter miner is a heavy‑duty standard integrated tunneling‑and‑anchoring unit that combines rock cutting, gangue conveying and synchronous bolt support. Equipped with a dual‑power cutting motor and a cutting head with 700 mm telescopic stroke, it breaks rock with uniaxial compressive strength up to 85 MPa and delivers cost‑effective operation at 60 MPa.
The EBZ200M‑2H bolter miner is a heavy‑duty standard integrated tunneling‑and‑anchoring unit that combines rock cutting, gangue conveying and synchronous bolt support. Equipped with a dual‑power cutting motor and a cutting head with 700 mm telescopic stroke, it breaks rock with uniaxial compressive strength up to 85 MPa and delivers cost‑effective operation at 60 MPa. Its standard body height suits roadways with normal clearance. The modular split design facilitates segmented underground transportation. Dual bolters enable parallel excavation and anchoring. With sufficient power reserve and reliable surrounding‑rock reinforcement, it performs efficiently in medium‑hard strata with regular roadway cross‑sections. For low‑seam working conditions, customers may select our low‑profile EBZ200M‑2H bolter miner variant.

Dual‑power Dual‑speed Cutting Head with Extra‑long Telescopic Stroke for Superior Hard‑rock Performance
The two‑setting cutting motor (200 kW /110 kW) runs at 46 r/min and 23 r/min. The 700 mm telescopic stroke enhances profile shaping capability and maximum rock strength capacity of 85 MPa. At the typical 60 MPa strata condition, it maintains stable power consumption and high advance speed; the long telescopic travel shapes roadway contours flexibly for smoother finished surfaces.
Standard Body Dimensions for Regular Roadways and Stable Terrain Adaptability
Weighing 87 t with a total length of 12.28 m, the machine stands 2.2 m tall with a maximum working height of 2.6 m. The 2.86 m wide tracks distribute weight at 0.17 MPa ground pressure for excellent anti‑sinking performance, while ±18° climbing capacity reliably negotiates undulating underground terrain.
Parallel Excavation & Anchoring with Wide Support Coverage for Higher Safety
Two bolt drills deliver 350 N·m torque at 500 rpm with 30 KN anchoring force per point. Support height ranges 3.5–5.1 m, support width 4.5–6.1 m with a supported area of 4.2 ㎡. Anchoring proceeds simultaneously with tunneling to eliminate relocation downtime and stabilize surrounding rock promptly against collapse risks.
Wide Shovel Plate for Efficient Material Collection and Uninterrupted Discharge
The 3.6 m full‑width shovel plate with 350 mm sumping depth thoroughly gathers low‑lying gangue and prevents blockages even under thick gangue conditions, matching heavy‑duty tunneling rhythm for continuous muck removal.
Convenient Split Transportation and Mine‑compatible Power Supply for Long‑shift Operation
The heaviest single non‑detachable component weighs only 5.2 tons; four segmented assemblies pass standard underground haulage routes easily after splitting. The 132 kW oil pump motor pairs perfectly with the cutting system. AC1140 V‑50 Hz power input conforms to mainstream domestic coal mine standards, ensuring low failure rates and easy maintenance during long continuous shifts.
