Tool for identifying project energy interdependencies

A method of optimizing parameters of an energetic pulsejet boring system constrained by project requirements and a maximum total energy restriction, comprising the steps of:

• a) receiving defined system inputs [503];
• b) receiving a maximum allowable energy, “Emax” [505];
• c) receiving said project requirements defining acceptable ranges of a plurality of system parameters [507];
• d) determining an integrated set of parametric equations modeling the total energy of the system in terms of said system parameters;
• e) using a computing device, calculating a solution set of entries each having system parameter values for each total energy value of the system, over a plurality of system parameter values, using the defined system inputs;
• f) locating minimum energy points (“MEP”) [513] in the solution set;
• g) if the values of parameters at an MEP are not within the acceptable ranges [515], then selecting the parameters values to move away [517] from the MEPs until parameters are encountered which meet said project requirements;
• h) if no entries are encountered before the energy of the system reaches Emax [523], then indicating that there is no acceptable design solution based upon the given inputs [525].

A method of determining the system parameters values of a pulsejet boring system having a defined mission duration, hole depth, hole diameter, rock density, fluid energy density, fluid density, for a particular drilling methodology creating a specific particle size, comprising:

• a. receiving an acceptable ranges [507] of hole size, penetration rates, and total energy of the system;
• b. creating a integrated set of parametric equations [509] in which:
• i. comminuting energy is a function of hole depth, hole diameter and specific energy of rock;
• ii. exhaust & retention energy is a function of exhaust gas volume and mission duration;
• iii. fluid flow energy is a function of fluid volume and mission duration,
• iv. total energy as the sum of comminuting energy, exhaust and retention energy, and fluid flow energy;
• c. using a computing device, calculating total energy entries [513] for various hole sizes and penetration rates as a solution set;
• d. determining [515] if the solution set has entries with a hole size, penetration rate and total energy within the acceptable ranges received in step “a” above;
• and
• e. using parameter values of the solution set entries within the acceptable ranges as the system parameter values for optimizing the system.
