FIELD: mining.SUBSTANCE: device for formation of tunnels contains cutting head provided with electric or hydraulic motor, mechanism for cutting head actuation, hydraulic mechanism connected to cutting head and designed with possibility of pushing of cutting heads towards the end of tunnel during material removal and supporting structure for support of previously formed part of tunnel. Supporting structure is designed so that to provide support on the tunnel surface both during stop and movement along the tunnel. Cutting head is designed with possibility to move independent of supporting structure. Besides the device has a conveyor for transportation of removed material from cutting head to the place distant from the cutting head during formation of part of tunnel. Also the method of tunnel formation using this device is proposed.EFFECT: reducing time for tunnel driving.31 cl, 4 dwg |
