AQ RSM Rock Quality – Report Data Sheet (Version 1.3 new English – Data for Commerce) (TPD1911048)

REPORT OF THE BENCH IMPACT : Measured Waves with Spectrum and Computation of RMS and AQ


1)   Meaning of data

Reported quantities:

Formula Placeholder

RSM: is the Rock Strength Measure, referred with earth dynamics to the Laboratory Test for 1 Sample of Sector 1 and its asymmetric speed record in Z and X directions composed as v1-v2to give the Shear Strength Q.

Average Quality: is the Percentage Quantity of the Bench surely better then 1 Bench previously commercialized of Sector 1 with measured v1 and v2 in Z and X directions. Reference:
