Abstract: A Tunnel Boring Machine (TBM) with a circular cutting profile includes secondary cutterhead components that produce a semicircular-arched tunnel profile for use in underground mining and/or civil construction operations, e.g., for boring in material containing rocks with
Unconfined Compressive Strength (UCS) of up to 200 MPA or stronger. The machine is particularly suited to excavate long access tunnels, mine development drifts, road tunnels, and other types of tunnels that require flat bottom, semicircular-arched profiles. The substantially flat tunnel floor allows immediate and effective use of standard vehicles for material and crew transport as well as other construction and mining activities.

Abstract: Systems for forming or extending a tunnel or shaft within a working surface may include a ram accelerator assembly for accelerating a projectile into geologic material to weaken a region of the geologic material. A cutting tool may then be used to remove the weakened material. A collection assembly may be used to move debris away from the working surface while the projectile and cutting operations are performed to enable generally continuous use of the system. The number of projectiles that are accelerated and the rate at which projectiles are used may be controlled based on characteristics of the geologic material and the rate at which created debris may be removed.

Abstract: A propulsion control device of a 3D printing-based tunnel boring machine, includes two propulsion control modules, and each of which includes tunnel support assemblies, a propulsion control assembly and a barrel body, where a propulsion sliding sleeve is arranged on an outer surface, and several tunnel support assemblies are arranged on an outer side of each propulsion sliding sleeve. Support plates on the two propulsion control modules alternately rise to support a 3D printed tunnel pipe. In the propulsion control module with the support plates in a closed state, a propulsion hydraulic cylinder controls a propulsion hydraulic cylinder extending end to contract, so as to pull the propulsion sliding sleeve to a front section of the barrel body; and in the propulsion control module with the support plates in a support state, the barrel body continuously advances relative to the propulsion sliding sleeve.

Abstract: A boring machine comprises a forward section, a rear section, a parallel link mechanism, stroke sensors, pressure sensors, and a controller. The parallel link mechanism includes eight thrust jacks that change the position and attitude of the forward section with respect to the rear section. The controller computes a target allocation force to be allocated to eight thrust jacks on the basis of the sensing result from the stroke sensors and the pressure sensors, and controls the thrust jacks to perform stroke control on six of the thrust jacks and perform force control on two of the thrust jacks.

Abstract: A drill bit exchange device for a shield tunneling machine includes: a housing with an aperture; a valve body housed in a chamber of the housing, the valve body being pivotable about a pivot axis (Ob) inclined at a predetermined angle with respect to an axis perpendicular to the front of a cutter head; a bit-housing hole formed in the valve body to detachably accommodate a bit; and an exchange seal recess located at the front of the chamber and at a symmetrical position from the aperture with respect to the pivot axis (Ob). The valve body is pivoted about the pivot axis (Ob) to move the bit, which faces the aperture, to the exchange seal recess, allowing the bit to be removed from the bit-housing hole and exchanged.

Abstract: An auxiliary tunneling apparatus includes a reaction force receiver and first and second split components. In the excavation of a second tunnel by a boring machine, the reaction force receiver forms a replacement face of a side wall of the second tunnel on a first tunnel side where the first and second tunnels intersect each other, and a gripper of the boring machine pushes against the replacement face. The first and second split components are installed to push against the side wall of the first tunnel, support the reaction force receiver within the first tunnel, and move back and forth with respect to the side wall of the first tunnel.
