conditions, e.g. drained or undrained, flexible or rigid (Pépin et
al. 2012).
The cyclic simple shear testing and shaking table testing
were modeled numerically to verify and calibrate a constitutive
numerical model used to simulate the dynamic behavior of
tailings (James 2009).
Large-scale laboratory testing of the interaction between
tailings and waste rock inclusions with respect to infiltration
and drainage capacity and the potential for clogging is in
progress.
An actual impoundment with WRI is being monitored to
assess its response following tailings deposition.
9 CLOSURE
Waste rock inclusions can provide a number of environmental
and geotechnical benefits and are a viable option in the
sustainable development and operation of mining facilities.
Ongoing work is underway to further validate the concept and
the results presented here.
