"This supplement describes soil testing methods relevant to open pit mining. For grain size analysis particles are sized by sieving and sedimentation. Consistency limits - shrinkage, plastic and liquid limits - are arbitrary measures of soil behaviour determined by standard soil mechanics procedures. Moisture density relationships when sample material is limited are determined using the Harvard miniature compaction apparatus. Triaxial tests with pore pressure measurement allow the effective stress parameters of soils to be determined; a triaxial cell with pressure monitoring instruments is used. The field vane shear test allows the undrained strength of saturated clay to be determined in situ"--Abstract. Slopes (Soil mechanics) Strip mining Gyenge, M. Ladanyi, B., 1922- Canada.
