Introduction of EBZ135 EBZ135L Mining Machinery Tunnel Boring Machine
EBZ135 EBZ135L Mining Machinery Tunnel Boring Machine is a sort of tunneling road header equipment integrated with continuous cutting, conveying and moving. It can achieve the drivage in coal roadway, coal-rock roadway, and also in other mines or civial tunnels. Our road headers were tested in complicated mining and geological conditions and they are capable of woring on the rock with up to 60 Mpa hardness.
