Effect of the Explosive Type on Rock Damage/Fracturing and Seismic Radiation
Abstract
In 2016, we conducted a series of chemical explosions using aluminized and non-aluminized explosives in the same location to quantify the effects of the gaseous products on the radiated seismic energy. Even though the experiment produced important results, the data analysis posed additional questions including: (a) the individual effects of the velocity of detonation, chemistry, and the temperature of the gaseous products on the seismic amplitudes and spectra, (b) the effect of the oxygen balance of the explosives on their performance and the seismic wave amplitudes, and (c) the effect of the borehole and other man-made features on the non-isotropic seismic radiation. The current project is an extension of the previous experimental study (Contract No FA9453-16-C-0021) intended to isolate and quantify the effects of the individual explosive properties on seismic amplitudes and spectra. The new experiment included 4 additional explosions (two COMP B shots, one HBX-1 shot and one Octol shot) in hard rock. The combination of the explosives is designed to address the unresolved issues of explosion coupling and energy partitioning between the thermal and mechanical explosive components.
