| 520 | 3 |a"Sampling is influenced by geology and geography of a mine site, and by the requirements of design. Rock samples are usually obtained by coring with diamond drills or occasionally by removing surface blocks. Soil can be sampled by auger or, if undisturbed samples are required, by tube sampler. Undisturbed samples of cohesive soil can also be obtained by cutting blocks of soil from the side or bottom of a trench. Rock specimens for triaxial testing must be carefully ground to produce parallel, flat ends to a close tolerance. Shear box specimens are carefully aligned and then grouted into the shear box. "Undisturbed" soil specimens can be cut from field samples with special tools; however some disturbance is inevitable. Clay specimens must be protected from drying"--Abstract. |
