Engineering Physics Annotation << Back PHYSICAL MODEL OF THE PROCESSES OF SECONDARY TECHNOGENIC DAMAGE OF THE BIOTA DURING THE FORMATION OF ROCK DUMPS OF MINING ENTERPRISES YU.P. GALCHENKO, A.N. PROSHLYAKOV The infl uence of the movement of the rock mass, at which it will be located behind the outer contour of the dump, is considered. The mechanism of formation of a dynamic ecotone and a calculation scheme for determining its width are shown. A mechanism for the formation of a dynamic ecotone is proposed, and a scheme for determining its size is proposed. When distributing pieces of rock over the entire area of a dynamic ecotone, a method is proposed for calculating the geometric parameters of a technogenic new formation. To determine the degree of technogenic damage to biota within the dynamic ecotone, an indicator of the projective coverage of biota by the breed is proposed. The change in the zone of secondary damage to biota during the formation of the final contour of the dump is shown. The distribution of the general indicator of technogenic damage to biota as the volume of the dump increases. Keywords: waste dump, dynamic ecotone, projective cover, technogenic neoplasm, zone of secondary damage. DOI: 10.25791/infizik.11.2021.1238 Pp. 39-45.
