STATIC AND DYNAMIC ELASTIC PROPERTIES OF ROCKS FROM THE CANADIAN SHIELD

As part of a number of research studies in the Canadian shield associated with the stability of underground mine openings, seismic reflection surveys, and the proposed use of a tunnel-boring machine (tbm) for developing mine headings, a long-term laboratory rock mechanics program has been conducted to determine the static and dynamic elastic properties of samples of igneous and metamorphic rocks from the Canadian shield. This paper reports the results of 174 measurements of static elastic modulus and 152 measurements of uniaxial compressive strength for these rocks as a function of dynamic elastic modulus. There is a good correlation between static and dynamic elastic moduli, with the two values converging as the moduli increase in magnitude. The correlation between compressive strength and dynamic elastic modulus is not as good as that of the static elastic modulus. It is clear that if valid correlations are to be established, the environment in which the rocks specimens are stored and the experimental tests are performed must be carefully controlled. This is particularly true if a correlation between strength and an elastic property is to be established. (TRRL)
