AbstractSoil encountered in mining operations on the Precambrian Shield are almost all glacial in origin, ranging from well drained sand and gravel deposits to the silts and clays of glacial lakes. The character of typical glacial clays is described and the reason for their unusual properties, an artificially high natural moisture content, is explained. Failures of soils of this type at the Josephine and Beattie mines are summarized, followed by outlines of successful engineering operations involving the same soil types, including the draining of Steep Rock Lake for iron mining purposes. A table lists soil problems in relation to mining, correlated with principal soil groups. A short bibliography on Soil Mechanics is included, the purpose of the paper being to introduce mining engineers to the aid that can be given to their mining operations by the application of Soil Mechanics.
