Technical and economic assessment of existing and projected enterprises for the development of placer mines
Authors: Kostromin M V , Panina T Y 
Published: November 2019

Abstract
The development of placer mines is a significant source of replenishment of Russian reserves with precious stones and precious metals. Currently, the development of placers is carried out in the vast territory of the Far East, Transbaikal, Eastern and Western Siberia, Altai, Ural. The efficiency of mining operations is significantly influenced by geological, mine engineering, climatic factors, the physical and mechanical properties of rocks, the physical state of placers (frozen, thawed), location (distance from settlements and communication routes), the percentage of clay material, etc. Based on these factors, the technical and economic indicators of the same-type mining machines (for example, drag diggers) often differ significantly (sometimes several times). In this regard, the method of complex technical and economic assessment of operating and projected mining enterprises for the development of placer mines has been developed. The method includes the evaluation of the mines according to the following technical and economic indicators. 1. Indicators characterizing operating conditions. 2. Indicators characterizing the potential of an enterprise. 3. Indicators characterizing the enterprise work results. Mathematical processing of all groups of factors in natural units of measurement is not possible due to the difference in units of measurement and a large amount of variation. Therefore, it is necessary to bring all the indicators in the appropriate form. These requirements coincide with the system of indexing (coding) of the source data, in compliance with the necessary principles. The article provides an example of coding. Further, the classification of the enterprises using the Euclidean metric is carried out. The proposed criteria are the basis for a comprehensive assessment of mines, as well as for obtaining linear regression techniques, a simple regulatory function that establishes the reciprocity between the calculated values of the economic results from the conditions and capabilities of the enterprises. The deviation of the calculated value from the actual value allows to judge how effectively (or not effectively) an enterprise operates under the appropriate conditions and opportunities. The article provides examples of determining the results of the activities of particular Transbaikal enterprises by this method.

Published: November 2019

Abstract
Often uncontrolled construction with insufficient consideration of the geotechnical and hydrogeological conditions of the territory, the increased man-made impact on the slope in the conditions of growing urbanization are leads to serious problems: landslide deformations and emergencies on the coast of the Cheboksary Reservoir, on the territory of the Cheboksary urban district and in the adjacent territories of Chuvash Republic. The increase in recreational load on coastal geomorphic systems also contributed to the activation of landslide, erosion, deflation and other dangerous relief-forming processes, and also affected the quality of water resources. The problem of assessing the stability of hazardous landslide slopes and slopes for civil, transport construction and recreational development of the coast of the Cheboksary reservoir is analyzed in this article. Minimizing the risk and damage from hazardous slope processes, including landslide, depends on the knowledge of the structure of the landslide geomorphic system and the slope array, harmonization of the interaction of the components of the designed object with the components of the geological environment (GE). On the basis of a professional analysis of engineering and geological factors, correct design models are proposed, with exact values of the slope stability coefficient (Cs) and rational design solutions leading to a reduction in natural and man-made risks.

Abstract
The wide possibilities of modern interval metering devices installed at substations of distribution grid companies are not fully used today. In the process of measuring the electrical parameters of the network meters, there may be abnormal modes of electricity metering substations, resulting from intentional or negligent actions of staff, failure of existing equipment or parts thereof. The considered circumstances lead to large economic losses of electric power enterprises, expressed in the underestimation of electricity. One of the effective ways to solve this problem is the use of intelligent techniques to identify incorrectly operating metering stations of the substation network, as well as the development of an optimal model of an automated multifunctional information and measuring system for industrial use and software implementation. The purpose of the study – the development of methods of control and diagnosis of normal operation of the substation electricity metering system, determined by compliance with the reliability of electricity metering substation information and measurement systems. On the basis of the offered method the algorithm of control and diagnostics of modes of operation of the information-measuring equipment of system of the account of the electric power of substations is offered. The software for a two-level multifunctional measurement system combining the functionality of an automated electricity metering system, a system for monitoring and diagnosing the modes of operation of the information and measuring complex of substations, and a system for monitoring the quality of electricity has been developed. The results of the research were used in the development of recommendations for the construction of automated information and measurement systems based on existing power metering systems of substations for distribution grid companies. The developed technique and the corresponding algorithm of control and diagnostics of abnormal operating modes of information-measuring complex of substations allow to quickly determine the technical condition of the metering system of substations, to plan corrective measures to eliminate violations.

Abstract
For many years fuel and energy and ore-dressing industries have been the sources of industrial waste which, if treated correctly, can be reused as secondary raw material resources accumulating earlier wasted investments and power costs. The article introduces possible ways of recycling both in our country and abroad. Basing on this, ways of reusing man-produced wastes in Grozny as bottom ash waste and chippings from rock crushing into spalls have been described. Study results showed that secondary man-produced raw material can compete with and substitute non-renewable natural resources as their chemical composition and quality parameters prove their unique nature, also it is possible to take into account solution of ecological problems. Developed formulas of multi-component bindings based on finely dispersed fly-ash and concretes with the use of enriched artificial aggregates promoted recycling of secondary raw materials and improving ecological situation in the region.

Abstract
Oil crisis and sharp increase of oil and petroleum market prices, resource limitation fastened the search for alternative energy sources. Among alternative energy sources renewable and especially received from vegetable biomass (fuel alcohol, vegetable oils) are of the greatest interest. With the account of this the article gives the results of studying the peculiarities of the bio-Diesel operational cycle and possibilities to adapt existing Diesels to biofuel. It has been determined that substitution of the Diesel fuel (DF) with rape-seed oil (RSO) and biofuel increases maximal and intermediate injection pressure, earlier start and greater injection duration, loss in frequency and oscillatory amplitude in the pressure pipeline after completing the injection. When RSO is used there appear increased inside lacquer film on the blowgun; which results in the needle valve immobility down to hanging up; needle valve immobility leads to the time lag of inlet and lengthening of the injection, increase in maximal injection pressure. There is quality loss of spraying the fuel, increase in non-uniformity and medium volume diameter of fuel drops, as well as penetration of the fuel jet into the air medium. Higher viscosity of the biofuel increases the injection rate due to leakage decrease in plunger pairs of diesel fuel injection pumps (DFIP).

Published: November 2019

AbstractThe paper deals with the problem of residential housing renovation projects for benefit of builders, citizens and state. The numerous interpretations of the “renovation” term we understand here as a complete renovation of the housing stock, i.e. demolition of old buildings and construction of new ones in contrast to their reconstruction and modernization. In other words, the renovation is considered as an urgent city-planning challenge involving changes in the field of territorial planning. On the example of the classic “Khrushchev” quarter of Irkutsk city, the authors propose a pilot renovation project with the distribution of roles and expenditures of all participants. The analysis conducted allows drawing a conclusion that renovation will be beneficial to the builder only if budget funds are invested in these projects in order to compensate the costs related to temporary resettlement of citizens from demolished dwellings. Another prerequisite is the governmental repurchase of apartments intended for resettlement of citizens from demolished housing at the prices not lower than those set by the authorities in the region. Citizens are ready to support renovation projects in case of their returning to their former place of residence in conditions improved from the point of view of the living environment comfort. To ensure the profit of the builder, the living area of the newly commissioned housing should exceed the area of the demolished housing by no less than one and a half times, provided that cheap technologies of modern prefabricated housing are used.

Published: November 2019

Abstract
The most important attribute of the existence of the totalitarian regime in the USSR was the repressive policy that influenced almost all spheres of life of Soviet society. The GULAG and GUPVI CAMPS, which spread throughout the country and absorbed millions of innocent human victims, became an integral part of the Soviet repressions. Siberia, which became a place of hard labor and exile in tsarist times, became in Soviet times a huge concentration camp for both Soviet citizens and foreigners. Why Siberia? There are several explanations for this: the extremely harsh climate of the region, which together with hard work had to «re-educate» the lost; huge deserted spaces that had to be mastered; large construction sites, for example, BAM, which is very profitable to use slave, almost free labor of prisoners or prisoners of war.
