Score influence of water saturation conditions on highly clay sands of noble metals for subsequent disintegration

The results of studies of highly clayey sands alluvial deposits of the Khabarovsk region. Identifi ed the nature of changes of elastic characteristics of sands, their monotony and marginal impact by water saturation. Found, the sands of gold Placer are complex enough to disintegration due to its high content of iron oxides, clay minerals kaolinite and montmorillonite. Proposed to address the problem effectively weakening the sands with high clay content use of the systems, including pulse and wave effects.
