EBZ200M‑2H (Low‑Profile) Bolter Miner
The EBZ200M‑2H (low‑profile) bolter miner is a heavy‑duty low‑height integrated tunneling‑and‑anchoring machine customized for low‑seam roadway conditions. It integrates rock cutting, muck conveying and synchronous bolt support in one unit. The dual‑power cutting system with a 500 mm telescopic cutting head breaks rock up to 85 MPa uniaxial compressive strength and delivers cost‑effective performance at 60 MPa.

It integrates rock cutting, muck conveying and synchronous bolt support in one unit. The dual‑power cutting system with a 500 mm telescopic cutting head breaks rock up to 85 MPa uniaxial compressive strength and delivers cost‑effective performance at 60 MPa. Its low‑profile structure fits confined underground spaces with limited clearance; the modular split design enables segmented underground transportation. Dual bolters realize parallel excavation and anchoring. With abundant power reserve and firm support, it excels at efficient construction in low‑height hard‑rock roadways. For conventional high‑clearance extra‑large sections, customers may choose our standard‑height heavy‑duty bolter miner series.

Low‑profile Design for Superior Adaptability in Low Seams
Standing only 1.7 m tall with a maximum working height of 2.3 m, it accesses low coal‑seam roadways inaccessible to ordinary models. The 11.87 m body length and 2.98 m track width distribute the 92‑ton total weight at 0.17 MPa ground pressure for strong anti‑sinking performance, while ±18° climbing capability handles undulating terrain reliably.
Dual‑power High‑power Cutting for Outstanding Hard‑rock Penetration
The dual‑setting cutting motor (200 kW /110 kW) runs at two speeds (46 r/min, 23 r/min) with a 500 mm telescopic stroke to cut rock up to 85 MPa. At the common 60 MPa strata condition, it maintains steady advance speed with controllable power consumption; the telescopic head shapes roadway profiles flexibly for better forming quality.
Parallel Tunneling & Anchoring Boost Efficiency and Safety
Two bolt drills output 350 N·m torque at 500 rpm with 30 KN supporting force per anchoring point. The support height ranges 3.0–4.75 m, support width 4.3–5.8 m with a supported area of 4.2 ㎡. Anchoring proceeds alongside excavation to eliminate downtime for equipment relocation and stabilize surrounding rock promptly to reduce collapse risks.
Wide Shovel Plate for Efficient Muck Collection and Discharge
The 3.6 m extra‑wide shovel plate with 410 mm sumping depth thoroughly gathers low‑position muck and avoids blockages even in thick gangue conditions, matching heavy‑duty tunneling rhythm for uninterrupted discharge.
Safe Split Transportation and Mine‑friendly Power Supply
The heaviest single non‑detachable component weighs only 8.85 tons; four segmented assemblies pass low‑seam haulage routes after splitting. The 132 kW oil pump motor coordinates perfectly with the cutting system. AC1140 V‑50 Hz power input complies with mainstream domestic coal mine standards for stable long‑shift operation and convenient routine maintenance.
