Rock Tunnel Multi-function Bolt Miner
EBH Series Rock-Tunnel Multi-Function Bolt Miner
The EBH-series rock-tunnel multi-function bolt miner combines cutting, bolting, conveying and dust suppression for fast development of rock and rock-and-coal tunnels in ground up to a Protodyakonov hardness coefficient of f12.
Features
Synchronous excavation and bolting: parallel, non-interfering cutting and primary support; the sliding-arm structure adapts to a range of bolt and cable spacings.
Digital cutting: automated cutting cycle, real-time drum-position and feed display, single-button start for raise, feed, cut and lower.
Safety shielding: temporary roof shield supports the back during cutting, bolting and machine maintenance.
Foam and water-spray dust suppression provides comprehensive at-source dust control.
Automatic shift logs transmitted via CAN/Ethernet to the shared terminal for production management.
Wireless remote operation and remote-room visualisation enable a path toward reduced face crewing.
