Ebz230m 4 Integrated Roadheader Bolter - China

The EBZ230M-4 is an integrated roadheader-bolter developed for underground roadway excavation, temporary roof support and multi-zone bolting.

It is a specially developed integrated system for tunneling, anchoring, and temporary support.

It directly addresses the safety and efficiency pain points of traditional separate tunneling and support operations, such as large unsupported roof distances, numerous personnel, and disjointed processes.

It is suitable for small-section semi-coal/full-rock roadways with a diameter of 3.1-4.8m and a pressure of ≤85MPa.

The machine is equipped with a 362kW powertrain and features four zoned anchor drilling rigs, allowing four people to simultaneously perform anchoring operations.

Dual hydraulic and electrical interlocks for tunneling and anchor drilling eliminate the danger of overlapping operations, enabling parallel tunneling, supporting, and anchoring operations.

This significantly reduces unsupported roof time, decreases on-site personnel, and simultaneously improves the efficiency of both tunneling and support.

Cutting power: 230 kW

Number of bolting rigs: 4

Maximum cutting area: 26.4 m²

Specified rock strength: ≤85 MPa

Machine weight: 95 t

Maximum drilling depth: 18 m Key Product Highlights:

● 230 kW Hard-Rock Cutting System: The EBZ230M-4 is equipped with a 230 kW cutter motor and a low-speed cutting head designed for full-rock and mixed coal-rock roadways.

● Four Independently Operated Bolting Rigs: Equipped with four symmetrically arranged anchor drilling rigs, one machine can replace a standalone tunneling machine plus multiple individual anchor drilling rigs, reducing the number of equipment required.

The four symmetrically arranged anchor drilling rigs can be operated independently, allowing four workers to drill and anchor simultaneously in designated areas, doubling anchoring efficiency.

● Hydraulic and Electrical Safety Interlocks: The tunneling and anchor drilling processes are equipped with hydraulic and electrical double interlocks.

During tunneling operations, the anchor drilling mechanism locks, and the cutting system stops during the anchoring stage, eliminating the risk of collisions during overlapping construction.

Combined with onboard advanced temporary support, support is provided as tunneling progresses, effectively reducing the risk of roof collapse and perfectly solving the safety problem of excessively long unsupported roofs in traditional tunneling and support systems.

● Onboard Temporary Roof Support: The temporary roof-support system is used after excavation and before or during permanent bolt installation.

It helps reduce the unsupported roof exposure at the working face and provides protection while operators carry out drilling and anchoring operations.

● The drilling rig uses adjustable cylindrical guide rails with built-in lubrication circuits, preventing jamming and wear during long-term operation.

Drilling depth can reach 18m, adaptable to various support techniques.
