  • Determination of the granulometric composition of the result of drilling and blasting operations in a quarry using neural networks

    The drilling and blasting method is currently the most widely used for mining rocks. An indicator of the high–quality drilling and blasting operations is the uniform granulometric composition of the exploded rock mass - the percentage of oversized ore pieces should be minimal. The percentage of oversized and its increase have a significant impact on the technical processes of transporting rock mass, leading to an increase in the costs of loading and transportation operations and secondary crushing of oversized ore masses. The paper describes the results of a study of methods for determining the granulometric composition of drilling and blasting operations using neural networks of segmentation Unet and FPN. Images taken from UAVs are used for analysis. A method of classifying ore by size has also been developed, which ensures the accuracy of the proportion of correct answers of more than 0.91. The expected result of the introduction of the system for automatic determination of the granulometric composition of drilling and blasting operations is the possibility of more accurate control over the quality of their performance.

  • Study of the features of the layout of the territory of a residential complex of increased comfort

    In this paper, we consider the aspects of identifying criteria for increased comfort of the territory of residential facilities. The concept of increased comfort is influenced by a variety of heterogeneous factors. However, a clear method for classifying these criteria has not been defined.The purpose of this work is to identify the criteria for increased comfort of a residential complex and study the features of the layout of these objects. This article discusses the qualitative and quantitative indicators that make up the concept of ""increased comfort"". The authors have studied the stages of organization of the territory of a high-comfort residential complex and their components. Parameters and environmental factors that influence decision-making in construction are identified. Functional zones of the territory of the residential complex of increased comfort are defined. In this paper, we propose a scheme that allows us to classify the criteria of increased comfort for a residential complex based on indicators of technical principles of organization and architectural and planning structure.

  • Calculation of savings in operating costs by increasing the weight of trains on the railway section

    Abstract: the results of the analysis of existing and projected volumes of export cargo transportation in the freight-stressed areas of the Russian railway network to the ports of Azov-the black sea basin are Presented. It is established that the growth of traffic ahead of the development of the transport capacity of the studied railway directions. In this regard, foreign and Russian experience in the development of growing volumes of cargo transportation in terms of infrastructure constraints due to the organization of heavy train traffic has been studied. The measures of development of heavy traffic of trains are offered. The method of calculation of efficiency of the organization of heavy traffic on one of sites of the North Caucasian railroad is given.

    Keywords: Key words: export transportation, perspective volumes, infrastructure restrictions, ways of elimination, efficiency of heavy traffic

  • Development of a conceptual problem-oriented metamodel of figurative representation of complex system on the basis of a geographic information system

    This paper presents use metasystem approach to creation of complex system model. An opportunity to synthesize quantitative and qualitative models of separate subsystems in the form of a metamodel of complex system is distinctive feature of metasystem approach. Such approach gives the chance to develop and correct both the purposes of functioning of system, and a way of their achievement. The model of a geographic information system (GIS) acts as a metamodel basis. The GIS model integrates, processes and traces existential and coordinate information. The model of a geographic information system is in turn described as set of model of measurement of a condition of system and model of measurement of state of environment, including sets of rules, procedures and measuring means are considered. Separately in article the question of redundancy of data for which solution it is offered to use the National Instruments PXI platform which is turning on the reconfigurable input-output module (R-series module) is considered.
