We are going to conduct a unique experiment to quantify the effects of fractures on chemical explosion decoupling. We will conduct a series of four explosions (shots) ranging from 500 to 2000 lbs in order to extensively fracture granitic emplacement media. Seismic signals from the explosions will be recorded on temporary near-source and local stations as well as permanent stations. We will then re-drill the same blast holes, use borehole cameras to estimate fracture densities, and then reload the holes for a second series of equivalent yield shots.
