EBZ200 Boom-Type Roadheader
The EBZ200 boom‑type roadheader is a heavy‑duty high‑efficiency tunneling equipment integrating rock cutting, material loading and crawler conveying. It adopts a dual‑power cutting motor (200 kW/110 kW) and a cutting head with 700 mm telescopic stroke, cutting rock with uniaxial compressive strength up to 85 MPa and delivering cost‑effective performance at 60 MPa. With moderate total weight and compact layout, its main frame can be split for segmented underground transportation to suit roadways of various cross‑section sizes. Designed for pure high‑efficiency excavation without onboard anchoring modules, it can be replaced by our same‑power bolter miner series for scenarios requiring simultaneous excavation and support.

Dual‑power Dual‑speed Cutting Head with Long Telescopic Stroke for Excellent Hard‑rock Performance
The two‑setting cutting motor runs at 46 r/min and 23 r/min; the 700 mm telescopic stroke enables flexible roadway profiling and maximum rock strength capacity of 85 MPa. At typical 60 MPa strata, it keeps stable power consumption and fast advance speed. The cutting area ranges from 9 ㎡ to 33 ㎡ for neat roadway forming.
Wide Cross‑section Coverage for Flexible Roadway Adaptation
Positioned cutting height: 2.5–5.1 m; positioned cutting width: 3.6–6.5 m, fitting small‑to‑large roadway sections. The 10.5 m machine length and 1.72 m cover height create a compact outline for easy transfer in normal‑clearance roadways.
Low Ground Pressure for Stable Travel on Complex Terrain
The 58‑ton unit with 2.54 m track width achieves a low 0.14 MPa ground pressure for outstanding anti‑sinking performance. ±18° climbing capability handles undulating underground slopes reliably. The 250 mm cutting head sumping depth and 356 mm shovel plate sumping depth clear floor gangue to guarantee smooth movement.
Wide Shovel Plate for Efficient Collection and Continuous Discharge
The 3.2 m full‑width shovel plate gathers scattered gangue effectively and avoids blockages even under thick gangue conditions, sustaining steady material conveying to match heavy‑duty tunneling rhythm.
Split Transportation Design and Mine‑compatible Power Supply for Easy Maintenance
The split‑type main frame allows segmented haulage; the heaviest single non‑detachable part weighs only 6.1 tons to pass narrow underground passages. The dual‑setting oil pump motor (90 kW/110 kW) pairs with AC1140 V‑50 Hz power input complying with mainstream domestic coal mine standards, ensuring low failure rates and convenient routine maintenance during long‑shift operation.
