The essence and expediency in the use of partial indicators of economic efficiency evaluation and selection of environmental activities in the development of iron ore deposits in different mining conditions of its exploitation is identified. Methodical approach to economic evaluation of the effectiveness of environmental measures during developing of iron ore deposits by using of index environmental and economic changes level of the environment, specific costs for environmental protection and economic intensity of violations of the environment was improved. The generalized indicator of economic efficiency of production ecologization at enterprises of mining and processing of ore raw materials is grounded. Levels of this indicator by the character of environmental activities of the enterprise, the stability of its interaction with nature and level on environmental-safety, are allocated. The methodical substantiation of evaluation criteria and methods for measuring the cost-effectiveness of environmental measures during exploitation of iron ore deposits and practical aspects of assessing the level of ecologization of open-pit and underground mining in relation to the economy of mining enterprises are given.

Purpose.Substantiation of the managerial decisions to minimize the risks of mining the Bilanivske ferruginous quartzite quarry on its northeastern margin. Methods. The legislative, methodological, cartographic and literary materials on the topic, as well as the area of survey have been analyzed. The necessary cartographic plotting and calculations have been performed. An abstract-logical method is used to formulate conclusions and theoretical generalizations. Findings. The ecological risks of the Bilanivske quarry northeastern margin have been substantiated: presence of uranium ore deposits and a radioactive anomaly; geochemical pollution of groundwater; a depression cone, large in area and in depth, can be formed in the region; a probability of using explosives when mining the field; use of the Bilanivske quarry eastern side for laying mine shafts and adits. The question is raised about the expected expansion of the Bilanivske quarry boundaries to the east during its mining, as well as falling into the sanitary protection zone boundaries of the northwestern residential community of the Nova Haleshchyna urban-type settlement. It is recommended, when mining the Bilanivske and Kremenchuk (Haleshchynske) iron ore deposits, to develop for them a unified draft Environmental Impact Assessment (EIA) and a unified draft of sanitary protection zone, taking into account the fact of their mutual influence on the environment. Originality.For the first time, based on a combination of geological, mining, technological and spatial factors, a site (zone) of mutual risks has been identified in the Bilanivske and Kremenchuk (Haleshchynske) iron ore deposits development. The site has an area of 165 ha, bounded by the northeastern side of the Bilanivske quarry and the southern boundary of the planned Haleshchynske mine. Practical implications.The research results can substantiate the need to resettle the residents from the northwestern residential community of the Nova Haleshchyna urban-type settlement, taking into account the Bilanivske field development by the open-pit method. In addition, they also can serve as a basis for resolving disputes between these residents and the administration of Ferrexpo Belanovo Mining LLC (Bilanivske Mining Plant).

The article deals with the problematic issues and features of further development of iron ore deposits at great depths (over 400 m). The necessity of wide application of innovative competitive technologies for ore mining by open method and an increase in the efficiency of mineral processing in the conditions of modern trends of sustainable development is substantiated. To solve this problem, a systematic approach is applied based on the consideration of all technological processes, taking into account the impact of mining operations on the environment as a single organizational and technological complex. It is proposed to use the Neumann-Gale model as an economic and mathematical model for assessing the investment activity of mining enterprises, which takes into account the influence of the environmental factor on the efficiency of their functioning. Approbation of the model was performed at the PJSC “Southern Mining Factory” as an example of production and economic activity. The priority measures are presented for the implementation of ecologically balanced strategies in terms of environmental protection for sustainable development at modern mining enterprises in difficult economic conditions and uncertainty of price characteristics in the markets of iron ore raw materials.

Purpose is to develop efficient scheduling to excavate steep-grade iron-ore deposits using near-vertical layers relying upon production practices by an open pit of Poltava Mining-and-Processing Integrated Works (MPIW). Methods. The goal achievement involved system analysis of openwork scheduling for steep-grade iron-ore deposits by means of near-vertical layers in an open pit of Poltava MPIW; the scheduling process was structured from the viewpoint of decision-making under uncertainty. Findings. New scheduling methods to excavate steep-grade iron-ore deposits by means of near-vertical layers have been developed. The methods have been represented in the informal (descriptive) structure being mandatory for further transition to formalization of certain stages of technological decision-making during scheduling. To improve the scheduling efficiency, it is recommended to prepare initial process data using K-MINE software; Deswik software is recommended to determine economic indices as well as pit outlines. Originality.For the first time ever, a new mechanism of expedient spatiotemporal control of the specific excavation volumes while varying both “starting” time and intensity of a layer mining has been identified for the traditional openwork. The mechanism makes it possible to implement piecewise stable dynamics of annual output. Moreover, it also helps solve inverse problem, i.e. determine target values of spatiotemporal controlled parameters (i.e. “starting” time and intensity of the layer mining) for the required dynamics of ore and overburden excavation amounts. Practical implications. The proposed methods concerning scheduling steep-grade iron-ore deposit mining using near-vertical layers relying upon production practices by an open pit of Poltava MPIW have been tested successfully. Their efficiency has been proved. Currently, they are the key procedures being applied to schedule extraction using near-vertical layers in the context of the considered open pit. Keywords: iron-ore deposits, openwork, steep-grade layers, scheduling

Specific characteristics of iron ore deposits in Ljubija ore region are given by pelitoid iron ores (,,brand“) which occupy a substantial part of iron mineral resources, on which industrial production of natural iron oxide – pigments depends. This particular technology type of iron ore deposits, until recently was waste from mining production, and now when it is possible to implement new technological processes, that waste became an important commercial product. This paper presents the results of detailed geological research which lasted for a few years, as well as laboratory and tehnological tests. It presents the new data on the metallogenetic characteristics of the environment where iron oxides originate as a raw material for mineral pigments. In this paper, we answered and resolved dilemma about brand identity in adequate genetic iron types in Ljubija mining regions, about their specificity as well as the ore formations and geohistorical development. Through the technological characterization of the ore and its domain of application, we provide the basis for economic evaluation of the deposits of this very important mineral resource.

The article discusses the use of laser scanning technology for observing the deformations of an open pit walls in iron ore deposits. To carry out observations and analysis of the results obtained, an iron ore quarry was selected. The task of the study is to summarize methods and technical means used at mining enterprises for observing and measuring deformations in mountain ranges. The safety and efficiency of iron ore quarries is largely determined by the methods used to monitor the deformation process and calculate the stability of the pit walls and dumps. Based on the analysis of existing approaches to solving this problem, a conclusion was drawn on the advisability of using a laser scanning system for assessing sustainability. As a result, an analysis of the measurement results obtained in a digital model of the quarry near-surface arrays was obtained, which allows creating an electronic database for further use in surveying and geomechanical tasks.
