The role of adaptation as an interdisciplinary phenomenon and the necessity of its evolvement in engineering sciences, including mining, is stated. The notion of “open pit transportation system adaptation” is defined. The research was aimed to justify the choice of a methodology for adapting transportation systems in open pit mines, as well as to demonstrate possibility of the transportation system behavior determination and forecasting. In accordance with the definition, the state of a transportation system in the course of adaptation is described. It is shown that the theory of transportation systems for open pits and the theoretical principles are the mainframe. The theory features flexibility, is continuously developed and upgraded, meets the recent methodological standards and can serve the basis of structural and parametric adaptation. The case-studies of the efficient problem solution in mining using the universal simulation model of transportation system functioning in open pit mines developed at the Institute of Mining, Ural Branch RAS are presented. The scope of the applied research embraced: validation of parameters for loading-and-rehandling points in the dump truck- belt-rail transport flowcharts; determination of carrying capacity of rail tracks in open pits; justification of transportation system parameters for open pit mines based on the interactive modeling. The theoretical methodology framework for transportation system adaptation in open pit mines is presented, which is the joint application of the theory of transportation systems in deep open pit mines in structural and structural-and-parametric adaptation and the universal interactive simulation model of transportation system functioning in open pits in parametric adaptation.

Electric Energy Consumption

Belt conveyor (BC) transportation systems are considered to be the most effective for handling large volumes of bulk material. With regards to the rules of sustainable development, the improvement of belt conveyor technology is, in many cases, focused on environmental issues, which include the idea of energy usage optimization. The key issue in an energy-efficient transportation system is reducing the value of specific energy consumption (SEC) by increasing conveyor capacity whilst decreasing belt conveyor motion resistance. The main idea of this paper is to conduct an analysis of the modernization of existing belt conveyor transportation systems operated in open-pit lignite mines, in order to achieve relatively small electric energy consumption for a considered transportation task. The first part of the paper investigates the relationship between a conveyor’s SEC and material flow rate for various conveyor design parameters. Then, based on multi-parameter simulations, an analysis of electric energy consumption for a belt conveyor transportation system is carried out. Finally, an energy-saving, environmentally friendly solution is presented.

The Way

Until now and further in future the transportation problems of Vilnius will be caused by the mobility of inhabitants and their chosen communication means as well as the way of living in an urban structure or other type of environment. Regulation (management) of such a complex of factors is just a key to solving the problems. In today’s discussions no mention is made of the functional environment of tram or metro. Efforts to find proper development proportions for public and personal transportation systems are one of measures for a real problem solution. With this purpose in view actual social, political and financial environment as precondition for proper development of a transportation system, is indentified in the paper. Suggestions and arguments for implementing a tram system in Vilnius are given. Santrauka Vilniaus susisiekimo problemas kūrė ir toliau kurs gyventojų mobilumas ir pasirenkamos susisiekimo priemonės, gyvenimo būdas urbanistinės struktūros ir kitokio tipo aplinkoje. Tokios visumos reguliavimas (valdymas) ir yra problemų sprendimo raktas. Dabartinėse diskusijose apie tokią visumą kaip apie tramvajaus, metropoliteno funkcionavimo aplinką neužsimenama. Šio straipsnio tikslas – identifikuoti susiklosčiusią socialinę, politinę ir finansinę aplinką kaip prielaidų lygį kokybiškai susisiekimo sistemai vystyti.

Muruntau open pit mine has been in operation since 1967 and is one of the largest open pit mines in the world. As per the project of mining phase V effective since 2020, it is among the world’s three largest open pit mines. The distribution of ore reserves per horizons is analyzed with regard to nature-and-process zones delineated in Muruntau–Myutenbai joint open pit mine. The project parameters of the pit and the scope of mining operations were determined from the geological and mathematical modeling including the detailed survey data and borehole assay results. The open pit mining scenarios within the project limits of mining phase V up to 2030 are considered. The open pit mining scheduling is performed with regard to operational specifics of the deposit, number of nature-and-process zones and duration of the scheduling period. It is concluded that maintenance of the required gold content of ore to be processed needs stimulation of the annual mining output up to 50–60 Mm3 in the easterly direction of the pit at the preserved production output in all nature-and-process zones. To this effect, it is required to formulate a sustainable action plan, with the assigned performance indicators, with regard to the Extra Activity Progr am to Improve Production of Precious Metals at Navoi Mining and Metallurgical Combinat over the period to 2026 and further on to 2040. The authors appreciate participation of Head of a Department at VNIPIpromtekhnologii, Candidate of Engineering Sciences A. V. Seleznev in this study.

Comparison Of Equipment

Chernogosky open pit mine integrates truck-and-shovel system of mining with overburden rehandling to internal dump with a set of walking excavators for rehandling of overburden to mined-out area of the pit. It is possible to improve efficiency of stripping in the conditions of Chernogorsky OPM by reducing percentage of stripping with more expensive handling system. The relevant research and solutions to this effect are presented in this article. Comparative characterization of mining conditions and parameters of mining systems applied is given for open pit mines Chernogorsky, Turnui, Nazarovsky, Vostochno-Beisky and Izykh. The comparative analysis points at the need to account for difficulty of mining and process sites in comparison of equipment productivity. High concentration of mining machines, which is conditioned by narrow mining front and simultaneous operation of five faces, as well as blasting operation implemented every 1-2 days, are recognized as the main constraints of excavator capacity in mining with direct dumping in Chernogorsky open pit mine. The management and engineering solutions implemented in the mine and resulted in higher efficiency of draglines are described.
