ABSTRACT: The available
measurements of the geo-mechanical properties of rocks in Southern Ontario and
the neighbouring regions (New York, Ohio, Michigan, Indiana, Illinois,
Wisconsin, and Minnesota) are summarized and presented. These measurements were
compiled from available published data in the relevant literature and also from
data that were collected from major underground projects in these regions. The
compiled data are presented in three categories: measured in-situ stresses in different rock formations; calculated
strength, stiffness and deformation including time-dependent deformation
properties; and the measured dynamic properties of intact rock specimens from
different rock formations in Southern Ontario and the neighbouring regions. The
data presented in this paper can be used as a resource for preliminary
evaluation of the geomechanical properties of the rocks in these regions. The
presented geo-mechanical properties were generally obtained from in-situ measurements and from laboratory tests that were conducted
on intact rock specimens from freshly excavated rock samples. Moreover, the
time-dependent deformation properties of rocks in these regions were obtained
from laboratory tests that were performed on intact rock specimens submerged in
water. However, the influence of drilling fluids such as bentonite slurry and
synthetic polymers solution, on the geo-mechanical properties of rocks is not
evident and needs to be investigated.
