Abstract

Piezoresistive transducers, piezoelectric sensors and seismographs were used in conjunction to determine pressure values at different distances from the point of detonation of a series of charged boreholes. The experimental data were processed and correlated. By a semigraphical solution, the borehole pressure was determined indirectly. Based on this solution, formulas for approximating detonation pressure of several investigators were evaluated and verified, which indicated that one of them is the best suited for the South Florida region. The results indicated that the borehole pressure was approximately 1/8 of the specified detonation pressure of the explosive.
