The voids created by the projectile impacts may also control the material that is removed and the shape of a resulting section of the tunnel or shaft.

Projectile drilling system

A hole in geologic material, such as a wellbore, may be extended by impacting the working face of the hole with high velocity projectiles. A tube may be placed within the hole, and the lower end of the tube may be sealed to prevent ingress of material from the hole into the tube. A projectile may be accelerated through the tube, such as by igniting a combustible gas mixture to impart a force to the projectile. The impact of the projectile may extend the hole. In some cases, accelerated projectiles may be used in conjunction with a drill bit to drill a wellbore or other type of hole.

Projectile augmented boring system

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 more rapidly, with lower energy use and less wear on the cutting tool than use of the cutting tool independently. 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, allowing an operation to be optimized for speed, cost, stability, or other factors.

Tunneling and mining method using pre-conditioned hole pattern

Systems for forming or extending a tunnel or shaft within geologic material may include a ram accelerator assembly for accelerating one or more projectiles into geologic material to weaken a region of the geologic material. The projectile(s) pre-condition the geologic material, such as by forming one or more holes in a central region of the material or to define a perimeter of the region to be displaced. A cutting tool or subsequent projectile impacts may then be used to remove the weakened material. The voids formed by the first projectile(s) cause compressive forces from subsequent impacts or cutting operations to be converted to tension forces that more efficiently break geologic material, which may fall into the voids created by the first projectile(s). The voids created by the projectile impacts may also control the material that is removed and the shape of a resulting section of the tunnel or shaft.

Projectile drilling system

Systems for drilling or tunneling include an assembly for accelerating a projectile through a first conduit into a region of geologic material, which generates debris. The debris may be reduced in size by moving the debris to a crushing device located in a second conduit using a conveying device, such as an auger. The reduced-size debris is then moved toward the surface using fluid movement. A third conduit may be used to provide and remove material from the bottom of the first conduit to control pressure at the end of the conduit to prevent ingress of material into the first conduit. Water jets or other types of devices may be used to cut or deform a perimeter of a region of geologic material before the projectile is accelerated to control the shape of the borehole and the manner in which debris is broken from the geologic material.

Method for cooperative transport of parcels

The system and methods disclosed allow cooperative transport of parcels by aggregating excess carrying capacity of participating individual transport agents planning on or actually engaging in travels. Parcels are accepted at a sorter where a transport agent, who is traveling generally in the direction the parcel needs to go, picks it up and carries it along to the next sorter. This process continues until the parcel arrives at the sorter closest to the final destination. This aggregation increases utilization efficiency of available modes of transport and results in many benefits including: saving energy by reducing overall fuel usage, decreasing overall vehicular pollution generation and congestion, and reducing wear and tear on transportation infrastructure.

System for acoustic navigation of boreholes

Methods for generating boreholes used for generating geothermal energy or other purposes include forming the borehole by accelerating a projectile into contact with geologic material. Interaction between the projectile and the geologic material generates an acoustic signal, such as vibrations within the formation, that is detected using acoustic sensors along a drilling conduit, at the surface, or within a separate borehole. Characteristics of the geologic material, such as hardness, porosity, or the presence of fractures, may be determined based on characteristics of the acoustic signal. The direction in which the borehole is extended may be modified based on the characteristics of the geologic material, such as to create a borehole that intersects one or more fractures for generation of geothermal energy.

Ram accelerator system with baffles

One or more ram accelerator devices may be used to form one or more holes in geologic or other material. These holes may be used for drilling, tunnel boring, excavation, and so forth. The ram accelerator includes one or more baffles that are downhole. The ram accelerator devices propel projectiles which are accelerated by combustion of one or more combustible gasses in a ram effect to reach velocities exceeding 500 meters per second. An endcap may be deployed within a tube of the ram accelerator device to prevent incursion of formation pressure products such as oil, water, mud, gas, and so forth into a guide tube of the ram accelerator. The endcap may be maintained in place within the hole at least in part by the one or more baffles. During operation the projectile penetrates the endcap and at least a portion thereof impact a working face.

In another example, gasses may be delivered by the rails.
