Conclusion
The inference is that work produced by an explosive tends to be a result of explosive generated gas pressure rather than the more constant shock energy.
The breakage and adiabatic work respond to calculated borehole pressure relationships with a very high correlation. This indicates that the primary mechanism for rock breakage is explosive generated gas pressure.
