Abstract
Steep Rock Lake, in north-western Ontario, Canada, had to be dammed and drained in order to gain access to large deposits of high-grade iron ore beneath its surface. Lake bottom deposits proved to be varved clays with natural water contents higher than their liquid limits, thus proving to be unstable when disturbed. Ultimately, almost 300,000,000 cu. yd of such material will have been removed from the lake bed in the development of the several major ore bodies. Dredging has been used for this major excavation operation, using suction and cutter-suction dredges. Stable slopes adjacent to the two open pits were successfully designed using the principles of soil mechanics.
