STRAIN DISTRIBUTION AROUND UNDERGROUND OPENINGS: STATISTICAL RELATIONSHIPS FOR CERTAIN ROCK PROPERTIES
A COMPARISON IS MADE BETWEEN ALL POSSIBLE PAIRS OF 19 DIFFERENT PHYSICOMECHANICAL PROPERTIES OF ROCKS. USEFUL CORRELATION COEFFICIENTS FOR SEVERAL PAIRS OF PROPERTIES WERE IDENTIFIED. THE ANALYSIS WAS BASED UPON SOME 1,000 SETS OF DATA ON 25 DIFFERENT ROCK TYPES AND INCLUDED 5 DIFFERENT FIELD TESTS AND 14 DIFFERENT LABORATORY TESTS. THE ONLY FIELD TESTS USEFUL FOR PREDICTING A LABORATORY TEST VALUE WERE THE PROPAGATION VELOCITY OF A LONGITUDINAL WAVE, WHICH GAVE AN R TO THE 2ND POWER OF 0.63 WHEN COMPARED TO UNCONFINED COMPRESSIVE STRENGTH, AND THE SCHMIDT HAMMER VALUES, WHICH APPEARED TO HAVE REASONABLE CORRELATIONS WITH WAVE VELOCITIES, STATIC SHEAR MODULUS, AND STATISTICALLY AND DYNAMICALLY DERIVED MODULI ON LABORATORY SPECIMENS. /AUTHOR/
