Engineering Analysis with Boundary Elements | Year: 2013

Fluid-structure interaction phenomenon, by its nature, is three-dimensional and consequently dependant on the shape of a dam and canyon that in-fact defines the spatial domain where the generated acoustic waves are spread. The complex topography of the terrain in general requires sufficiently large extent of reservoir to be included in the model, which is undoubtedly feasible if BEM technique is used. This paper shows that the irregular canyon shape dictates the most adequate location of the truncation surface that gives the smallest negative impact on calculation accuracy. The derived conclusions are based on various 3D analyses of a rigid dam-reservoir system with different shapes and lengths of the fluid domain, where the fluid is treated as incompressible and inviscid. The presented work contributes towards disclosure of the topographic site effects and towards promotion of simple and effective procedure for generation of BE mesh, which is quite accurate in following the topology of the terrain. © 2013 Elsevier Ltd.

The magnitudes of the hydrodynamic pressures at the dam-fluid interface depend on the amount of energy transmitted to the fluid by the vibration of the reservoir boundaries. Although the reservoir topology can have a considerable impact on the amount of generated energy, it has still not been adequately addressed. This article treats an arch dam-fluid interaction considering a compound wave field of compressive and dilatational waves in a reservoir with a complex topology. A truncation surface was located at a distance beyond which the simulated wave field has only negligible effects. © Copyright © IZIIS Institute of Earthquake Engineering.

The geochemical features of typical representatives of ferromanganese deposits are studied in the eastern Bureya and Khanka massifs (Russian Far East). Based on the major-, trace-, and rare-earth element distribution, the hydrothermal–sedimentary (with hydrogenic component) nature of their mineralization is established and the geodynamic setting and depth of ore formation are estimated. The differences in the depth and redox conditions of ore formation resulted in the metallogenic zonation of the Khingan block (Bureya Massif), which is expressed in a westward change in ore composition from the magnetite ores of the Kosten’ga–Kimkan zone to the hematite–magnetite and iron–manganese ores of the South Khingan zone. The conclusions about the participation of hydrothermal sources in the formation of ore mineralization of the studied deposits and the specifics of their localization require revision of the strategy of exploration and evaluation of ferromanganese ores in the southern Far East. © 2016, Pleiades Publishing, Ltd.

The article presents the sequence of computational simulation of stress-strain state of shovel's rotary support. Computation results are analyzed, the kingpin is specified as the most loaded element, maximum stress zones are identified. Kingpin design modification such as enhancement of fillet curvature radius to 25 mm and displacement of eyebolt holes on the diameter of 165 mm are proposed, thus diminishing impact of stress concentrators and improving reliability of the rotary support. © Published under licence by IOP Publishing Ltd.

The conception of the hidden information about sources of gravitational anomalies as joint fragment of the true model and disturbing objects has been introduced. It is shown, that in the presence of uncertainty inherent to inverse problems, the limit of possibilities of algorithms for constructing the best estimates of model parameters of sources is to maximize the guaranteed volume of hidden information. It is proved that optimal solutions of inverse problems, which realized the known conception of the minimax, have the maximum of the informativity (in this sense). Technologies of building of sufficiently representative subsets of feasible solutions, already tested on another class of inverse problems, have been offered. They have been fixed in the basis of minimax algorithms for solving inverse problems of the ore type. The examples of application of minimax algorithms of the solution of gravity inverse problems are given in the article.

Results of seasonal experimental investigations of natural draft in the potash mines after main fan stoppage are presented and analyzed. Underground mines with equal top elevations are considered. Three modes of natural ventilation depending on the season are determined: flow-through, local and convective ventilation modes. The mathematical model of unsteady heat exchange between mine air, shaft support and rock mass is proposed. This model allows prediction of natural draft intensity for flow-through ventilation mode. Also using system of linear convection equations we formulate natural ventilation stability criterion in case of convective natural ventilation mode for mine shafts after main fan stoppage. Formulated criterion based on Rayleigh number allows prediction of convective ventilation mode formation in shafts. © 2015 Elsevier Ltd. All rights reserved.

The Novaya Zemlya archipelago in Arctic Russia contains an Early Mesozoic fold-and-thrust belt that exposes a predominantly Palaeozoic succession. At a number of localities in northern Novaya Zemlya, Devonian carbonates within this succession contain solid bitumen.The Devonian succession was examined in two areas in northern Novaya Zemlya, one on the Barents Sea coast and one on the Kara Sea coast. On the Barents Sea coast, the Early Devonian succession comprises non-marine and near-shore marine siliciclastics which grade upward into shallow-marine platform carbonates. These facies are succeeded by Middle Devonian deeper-water mid-outer shelf black mudstones and shales. The Late Devonian succession consists of early Frasnian continental conglomerates and sandstones, and middle-Frasnian to Famennian shallow-marine platform carbonates.On the Kara Sea coast, the entire Devonian succession is dominated by shallow-marine carbonates, with deeper-water carbonate turbidites and shales in the late Lochkovian, marine siliciclastics in the Eifelian and non-marine sandstones in the early Frasnian.The Devonian palaeogeography of Novaya Zemlya is characterised by a deepwater slope-basin in the centre and east, and a shallow-marine carbonate platform in the south, west and north. Extensional tectonism influenced deposition of the Devonian succession, particularly during the late Givetian to early Frasnian.Solid bitumen is confined to carbonate facies and is most abundant in Early Devonian strata, occurring mainly within syn-tectonic fractures and associated secondary pore systems. In the mature Timan-Pechora Basin to the south of Novaya Zemlya, Devonian strata are an important element in the petroleum system; however, in the less-explored deep basins of the eastern Barents Shelf to the west of Novaya Zemlya, equivalent Palaeozoic strata are generally deeply buried beneath younger successions. Information from Novaya Zemlya therefore provides an important insight into the likely nature of successions and petroleum systems offshore. © 2010 The Authors.
