Engineering Physics Annotation << Back PHYSICAL JUSTIFICATION OF THE PROSPECT OF USING THE DEVELOPED SPACE IN THE UNDERGROUND TAILINGS STORAGE MODE YU.P. GALCHENKO In the phase separation zone, each particle moves along a trajectory determined by the combined action of the horizontal component, due to the continuity of the tailings storage process, and the vertical – gravitational one. Within the framework of the general concept of the created geotechnology, a general approach to the choice of design solutions is also determined based on the principle of creating conditions for the smooth operation of the laws of natural phase separation. In general, for the accepted structural model of the technology, the classical solid-liquid phase separation curve takes on a step-like shape and, in the approximated form, significantly flattens out in relation to the classical Stokes curve. At the actual size of the chambers and the amount of pulp (~1 m / sec) to lighten it, two consecutive cameras are quite enough. Increasing the flow width quickly reduces the value of the deposition path. As a physical model of the process, the model of the constrained joint fall of groups of particles in a liquid is accepted. In this case, the hydrodynamic conditions of fluid flow around each particle change dramatically (in comparison with free fall). The magnitude of the gradient of the relative velocity of the oncoming flows between the particles increases and, as a result, the tangential forces acting on each of them increase.
