Реферат

The findings of studies on high-clay placer sands in the Kolchan floodplain are presented. A new technology and a geotechnological complex of intense disintegration are recommended as an effective means of improving the development of high-clay natural and industrial gold placers with fine gold.

Ключевые слова High-clay gold placers, sand and gravel disintegration, water saturation, shear modulus,elastic modulus (Lamé’s first parameter), strength, elastic properties, technology of intensive disintegration, rippers, and control automation
