Bolter Miner Series

Integration: Integrating excavation, loading, transportation, support, drilling, and bolting functions into one, with a high degree of mechanization.
Safety: Triple-mode interlock for cutting, supporting, and bolting; onboard temporary support protects operators.
High efficiency: Multiple onboard bolting drills with multi-degree-of-freedom movement enable full roadway drilling and bolting operations without repositioning the equipment.
Labor reduction: Replacing manual drilling, bolt/cable anchoring, and temporary front crossbeam support operations to reduce worker numbers and labor intensity.
Convenience: Simple and compact structure, easy and intelligent operation; drills equipped with holders for quick rod removal.
Environmental improvement: Operators work under the protection of support systems, ensuring construction safety and improving the working environment.
