A method for driving tunnels, galleries, shafts or the like with a driving device (1; 2; 15), including: that a cutting head (4) rotating around a general axis of rotation (R) and having cutting elements directed essentially radially outwardly is applied against a rock surface to be worked. The rock cutting elements (13), are formed on cutting rolls (7) are brought to roll against the rock side during pressing against the rock and rotation of the cutting head (4), and the rock cutting elements during rolling are brought to cut sidewardly arranged grooves in the rock surface at a distance from each other. The invention also concerns a rotatable cutting head and a device and a rig for driving tunnels, galleries, shafts or the like. |

The invention relates to a method for introducing a vertical shaft underground and to a shaft driving machine set up particularly for performing the method, wherein a cutting wheel is rotated solely about a horizontal axis until a penetration trough having a predetermined penetration depth is formed, and the cutting wheel is then also rotated about a central vertical axis until a shaft foot is dug out to the penetration depth. A relatively high sinking rate is thereby achieved for the shaft. |

A tunnel excavator includes a pair of cutters arranged side by side at a front portion of a tunnel excavator main body. These cutters rotate in opposite directions for excavating the earth to form excavation and for causing the excavated earth to move toward a center area between the pair of cutters. The tunnel excavator further includes a screw cutter extending horizontally in a width direction of the tunnel excavator behind the pair of cutters at a lower level. The screw cutter has a pair of flights spiraling in opposite directions toward the center from opposite ends of the screw cutter for gathering the excavated earth to the center of the screw cutter. A soil plate generally extends along and behind the screw cutter and pushes the excavated earth as the tunnel excavator advances, but the soil plate has an outlet at a lower center area thereof for allowing the excavated earth to pass therethrough. A conveyor is provided behind the soil plate outlet. |

A system for inspecting a forward end portion in a tunneling machine including cutter bits and a chamber such as a tunnel boring machine or a shield tunneling machine. The system includes an apparatus for inspecting a forward end portion comprising at least one through hole provided on the partition wall for defining a chamber, an elongate member slidably and rotatably inserted into the through hole, an image sensor positioned at a forward end of the elongate member for observing a cutter bit or the inside of the chamber, an image display provided in the main body for displaying an image from the image sensor, and a connection for connecting the image sensor and the image display. The system also includes a method for inspecting a forward end portion comprising the steps of defining a cavity in the chamber or in the vicinity of the cutter bits by supplying compressed air, inserting an image sensor into the cavity, and observing the inside of the chamber or the cutter bits using the image sensor. |

A first mobile mining machine for cutting mining tunnels in hard rock, which includes a horizontally swinging wheel-like cutterhead assembly mounted on a crawler and base frame assembly. The cutterhead assembly consists of a transverse horizontal axis wheel-like drum on which are multiple peripherally mounted rolling cutter units.A second mobile mining machine for cutting mining tunnels in hard rock, which includes a horizontally swinging and vertically ranging wheel-like cutterhead assembly mounted on a crawler and base frame assembly. The cutterhead assembly consists of a transverse horizontal axis wheel-like drum on which are multiple peripherally mounted rolling cutter units.A method of cutting mining tunnels in hard rock which includes the steps of providing a wheel-like cutterhead assembly for cutting the hard rock, rotating the cutterhead assembly about its horizontal axis, plunging the rotating cutterhead forward into the hard rock, sweeping the rotating cutterhead assembly sideward in a first horizontal direction through the hard rock, plunging the rotating cutterhead forward into the hard rock, then sweeping the rotating cutterhead sideward in the other horizontal direction, and then repeating the last four steps. |

A tunnel driving installation has an advanceable support shield and cutting means co-operating at the front end of the tunnel and a continuous tunnel lining disposed rearwardly of the support shield and constructed from individual lining sections. In order to store and transport the tunnel lining sections within the tunnel lining apparatus is provided which comprises storage stations respectively located at the front and rear regions of the tunnel and a trolley vehicle for moving back and forth between the stations. The trolley vehicle has a container which serves to receive debris removed by the cutting means, and beneath the container the vehicle has shaped plates which serve to locate and support a series of lining sections. Both storage stations are composed of T-shaped rails laid on the tunnel floor so that the vehicle can pass over the rails. The rails of the rear station can be raised and lowered to effect transfer of the sections thereon to the plates of the vehicle whereas a lever or the like is provided at the front storage station to selectively cause the sections to slide along the plates of the vehicle onto the rails as the vehicle is moved. The front storage station moves up to follow the tunnelling progress and additional equipment is provided to take the lining sections from the front storage station and to place the sections in position to increase the length of the lining as the tunnelling progresses. |

A tunneling machine is disclosed which includes a cutter head rotatable in a first direction and in a second direction opposite the first direction. Inside roller cutters and gage (or outside) roller cutters are mounted on the head for cutting or crushing the end face of the tunnel. Each gage cutter is provided with a novel gage scraper means for clearing materials from the path of the gage cutter whether the head is rotated in the first or in the second direction.

Disc cutters are mounted at the forward end of support arms which are connected at their rear ends to a rotor which extends transversely of the tunnel. The rotor is driven to swing the support arms. As the arms move the disc cutters roll along arcuate paths across the tunnel face, each with its cutting edge penetrating into the tunnel face and cutting an arcuate kerf. The support arms are adjustable in position to establish new paths of travel for the disc cutters. Each disc cutter has a generally Vshaped cutting portion adapted to exert a lateral force on the material between a kerf being cut by such cutter and a previously cut adjacent kerf, to in that manner fracture such material and dislodge it from the tunnel face.

An apparatus and method for excavating tunnels with electrically generated shock waves. The tunneling apparatus is comprised of a rotatable barrel for cutting a peripheral ring about a core and a bit which simultaneously bores a hole in the center of the core. The drive for the rock bit also contains electrodes which are pulsed to produce shock waves in the core to peel off a desired thickness of rock layer.
