VeryBoring Tunneling System
Very Boring is a proposed new tunneling technology and the suggested name of any resulting tunneling company. Just consider the inestimable advantage of the recruiting poster: “Are you a VeryBoring person?” Or the incomparable pride bestowed by the company T-shirt: “I’m a VeryBoring person”
Rock Disassembly is a tunneling system based on an array of armored robotic arms using tools that break rock by pushing outward from behind the advancing face.
Instead of frontally grinding the rock to shards as done by today’s tunnel boring machines, we propose an array of robotic arms that drill into the rock face and push the rock out from behind. Sensors would continually observe the changing rock structure and AI would continuously control the tool array to optimize the rock removal process. Large chunks of rock would be broken out from the center and smaller pieces around the periphery. AI would guide each arms movement, coordinate the entire tool array, and supervise the overall tunneling system.
So far, most of the improvements in tunneling have been incremental, but “Rock Disassembly” has the potential to increase progress rates manyfold, even eventually achieving the Elon Musk touted “order of magnitude” increased in advance rate. This would result in a similar “order of magnitude” reduction in cost. And with that, many previously prohibitive or merely imagined tunnel projects would become possible. To interest others in the tunneling future that Very Boring’s technology might provide, we devote a note here to just a few interesting possibilities. (We invite any other enthusiasts to please chime in.)
Roadless Cities: Where cities are situated on rock all the roads and transport could be easily built underground, exclusively for electric vehicles. On the surface, buildings would be connected by walking and bike paths. Heavy and bulky items like pianos or rooftop air conditioners would be delivered at night by slow moving equipment on wide rubber tracks.
Other Tunneling Applications:
Water supply, high speed rail, highways, mining, drainage.
Pumped Storage - useful to store intermittent solar and wind energy.
Augmenting existing pumped storage sites.

ROCK DISASSEMBLY FRAMEWORK SYSTEM - PATENT WRITEUP
BACKGROUND The embodiments herein relate generally to systems and methods for disassembling rock structures for the purpose of constructing tunnels or other structures. More specifically, embodiments of the invention are directed to a rock disassembly framework system for storing a plurality of tools that disassemble a rock structure.
Igneous and metamorphic rock, due to distortions from tectonic activity, are usually cracked. Often, there are three orthogonal sets of joints. Such rock can be viewed as a very tightly packed assemblage of separate pieces. Sedimentary rock, due to its origin, is generally layered.
Breaking rock in tension is more energy efficient than grinding it into shards. But a single tension inducing device ranging over a tunnel face is slow and expensive. The two main methods of tunneling today are drill and blast and tunnel boring machines (TBMs). Drill and blast is cyclic. A lot of time is lost to changing machines at the face. TBMs stay at the face, but their full frontal grinding of the face is not energy efficient. Also, TBMs are very heavy and slow to mobilize.
Many energy efficient rock breaking technologies have been invented over the years. Among them are the CERAC Breaker, a mechanical drill/split device that was studied extensively by the U.S. Bureau of Mines. Micro blasting, which involves detonating squibs in water filled drilled holes has been demonstrated to be energy effective. Spiral Drill and Blast was studied at MIT through four phases and found promising.
Many other rock breaking mechanisms have been brought forward. The most efficient are designed to reach below the rock surface and push outward toward the free face. Controlled Foam Injection (CFI) is very promising. That method drills a hole and pressurizes existing joints inside the rock face, pushing the rock out in large pieces. However,none of these technologies have reached widespread commercial usage.
This can be understood by examining the following scenario. Imagine a tractor parked in front of a tunnel face employing any one of the aforementioned tools. As the hydraulic arm holding the tool ranges over the tunnel face, the rock breaking action may be wonderfully energy efficient. But overall advancement of the tunnel is still agonizingly slow. For fast progress, there is a need for many tools working in concert.
As such, there is a need in the industry for a rock disassembly framework system that addresses the limitations of the prior art. This would permit a plurality of tools to be secured therein so that they can work in concert to disassemble a rock structure with enhanced efficiency.

DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS
In certain embodiments, the rock disassembly framework system allows efficient rock breaking machines to operate together and continuously. As a result, the use of the framework system will increase the advance rate of the tunnel and the cost per foot will decrease proportionately.
In certain embodiments, the rock disassembly framework would allow many tools to attack the tunnel face simultaneously. The use of tool holding arms in the framework would allow for the change of tools rapidly. In one embodiment, an array of very sturdy armored robotic manipulators is applied to the tunnel face via the framework. Each manipulator arm is computer controlled. The many arms are coordinated by a supervisory computer program. A person, or AI, observes and modifies the guiding parameters to both optimize the tunnel advance and minimize maintenance.
The many arms, working together, make rock removal rapid and energy efficient. Chunks of rock rain down, but the armored arms can take it. If a tool does get broken it is rapidly exchanged. The entire framework and its backup system is designed for quick tool exchange. Tunnel progress will then be the product of the number of tools, their effectiveness, and the continuity of operation. In certain embodiments, the rock disassembly framework system catalyzes the potential in the many previous rock removal tools that have been long awaiting successful application.
In certain embodiments, a modular rock disassembly framework system can be configured into many sizes and shapes. Within each module many different rock disassembly tools could be interchanged to effectively "disassemble" any rock formation. The method of attack of the various rock disassembly tools could be varied as the framework is advanced through varying geological conditions. The operating system would flexibly vary the operating strategy of the whole equipment ensemble for minimum energy usage and maximum rate of advance.
In various embodiments, three lines of modules, Small, Medium, and Large could cover a very broad range of tunnel sizes, everything from perhaps 10 feet to 50+ feet. For example, see FIGS. 1-2. Here is a 25' diameter framework built from 10 same size, bolted-together modules. These could be the Standard Medium module. They would be 7.72 feet wide and thus would fit handily on a regular highway truck - no permits required.
The section at the bottom would contain a large chain conveyor. Broken rock would be swept onto the conveyor by the raker. In the central area of the tunnel face the rock would be "disassembled" by 9 "breakers" that run in the inner slots. Around them there would be 14 "trimmers" installed in the outer prismatic chambers. They would be breaking the periphery of the opening to the required size. Four of the chambers could hold probe drilling and grouting equipment as indicated.
For each tunnel project, the rock disassembly framework system would be configured from standard framework modules. A framework of any size would consist of a maximum number of modules and a similar number of wedge-shaped steel spacers. Because the framework is modular it can be configured over a wide range of sizes and shapes. By varying the number of modules and the spacers, most any desired tunnel size and shape could be excavated.
Varying the number of modules and the dimensions of the steel spacers could form any diameter in-between. Very often today the desired tunnel shape is horseshoe, but to accommodate TBM technology, the tunnel must be made round. However, a VeryBoring arrangement of modules would allow the rock disassembly framework system to build horseshoe-shaped tunnels. For example, see FIG. 8.
In certain embodiments, the modules for Large tunnels might be based on a 40·foot diameter, 16 module base framework. The framework would be built up from modules with three layers of tools: 14 inner "mega-breakers", 14 more breakers in the large prismatic chambers, and 24 trimmers, with, optionally, 4 probe/grout cells. As in the medium line, the width of the module is just 7.8 feet as before, readily truckable. Many of the tools would fit both the large and medium modules. Twelve large sections could make a framework 34.75 feet in diameter. More than 16 segments would make frameworks larger than 40 feet in diameter.
The small series of modules could also cover a range of tunnel sizes. The basic small module might be standardized on a 14-foot tunnel built up from eight 5.36 foot wide modules. Six of the same medium modules in a configuration can make a framework 11.8 feet in diameter. Fewer or more modules with appropriate steel wedge spacers could then build up frameworks through a range of sizes, up to around 31 feet. Many types of machine guides could be installed in the modules as shown in FIG. 4.
The basic function of the rock disassembly framework system is to hold the tools that "disassemble" the rock. The framework is modular and so can be assembled rapidly for any tunneling project and disassembled without loss at the end. Upon demobilization, everything would be reusable. The standard framework modules and all the rock disassembly tools that work within them could be trucked directly to the next job.
Worldwide, tunnels are required in many sizes and shapes, and must proceed through widely varying geologies. With the modular rock disassembly framework system, project mobilization by assembling modules and spacers would be rapid. Tools will be selected from an ever-growing library. The ruling criteria for the chosen tools for any instance of the rock disassembly framework system will be energy efficiency, speed, and hardiness. The many tools interchanged within the system will be the subject of many future inventions.
