摘要
FIELD: mining.;SUBSTANCE: development method comprises opening-up of developed field reserves, ditch driving along the whole length of the production block, water flooding of the production block for disintegration of clay sand and their subsequent improvement by the production complex with installation of pressure of head hydraulic transportation and concentration plant. Before grooving of slits by cross-cut and longitudinal passes of slit-cutting unit, and also water flooding of the production block for disintegration of clay sand and their subsequent improvement, using experimental and analytical methods the bending compression and tension characteristics of high clayey sands in various locations of placer deposits are determined. The dynamics of change of elastic characteristics in these sections is determined, the correlation of response curve of resiliency of sand at water saturation of separate sections of the field with the relative wave resistance of sand in these sections is studied, and grooving of cracks at the distance from each other depending on the change of response curve of sand resiliency of at water saturation is performed.;EFFECT: achievement of high level of disintegration of clay sands difficult for wash-out, minimising of process losses of valuable component and decrease of mining expenses.;3 dwg
