A simulation system [200] models and optimizes parameters for a pulsed liquid slug boring system employing an energetic fluid [7]. The simulation system [200] employs a fluid flow energy unit [251], an exhaust and retention energy unit [253] and a comminuting energy unit [255] to calculate energies of the system. Total energy unit [257] combines these energies. Fluid flow energy unit 251 receives fluid volume and calculates the fluid flow energy. Exhaust and retention energy unit 253 receives input from the exhaust energy volume unit [243] and mission duration unit [211] to determine the exhaust and retention energy. Comminuting energy unit 255 receives hole depth and hole diameter and specific energy of rock to determine the require comminuting energy. The simulation system [200] operates to determine optimum values of design parameters by searching for the minimum energy solution.
