Item Investigation of deportment of chalcophilic heavy metals in the waste rock of central coal enrichment plant “Chervonohradska” for the purposes of environmental safety of Lviv-Volyn coal basin(Видавництво Львівської політехніки, 2022-03-01) Kochmar, Iryna; Karabyn, Vasyl; Lviv State University of Life SafetyMining areas are centres of increased environmental danger. This is due to the development and operation of mines and subsequent beneficiation of coal, as well as the storage of significant volumes of empty waste rock in landfills. An important component of ensuring environmental safety is the investigation of the factors and ways of the impact of rock dumps on the state of the environment. In this regard, the article examines the forms of heavy metals found in the rock of the waste heap of the central coal enrichment plant “Chervonohradska” of the Lviv-Volyn coal basin. The environmental hazard factors caused by the distribution of various forms of lead, cadmium, zinc, and copper, based on establishing the migration capabilities of these elements in the technogenesis zone, are analyzed. It was determined that the gross content of lead reaches 16.32 mg/kg, cadmium – 5.84 mg/kg (exceeding clarke up to 29.2 times in siliceous siltstone and siltstone), zinc – 421 mg/kg (exceeding clarke up to 5.26 times in sandstone, siltstone and siliceous siltstone), copper – 112.89 mg/kg (exceeding clarke by 2 times in siltstone). The concentration coefficients of heavy metals in the samples were determined in relation to the gross form. The results of the research give a reason to evaluate the rocks of the waste dump in terms of the distribution of various forms of Pb, Cd, Zn and Cu as dangerous for the environment and unsuitable for use because in all the samples an excess content was observed in one form or another.Item Strategic Environmental Assessment – Underestimated Tool for Sustainable Subsoil Use(Видавництво Львівської політехніки, 2022-03-01) Karabyn, Vasyl; Shuryhin, Vladyslav; Shutiak, Sofia; Chmiel, Marek; Kulhánek, Rastislav; Lviv State University of Life Safety; Ukrainian National Bar Association; Politechnika Częstochowska; Comenius University BratislavaStrategic environmental assessment is an effective tool for improving the level of environmental safety in various areas. The purpose of the article is to identify and classify the main tasks of strategic environmental assessment in subsoil use, taking into account its role and functions in the subsoil management system, and to suggest ways to improve environmental safety in subsoil use by means of strategic environmental assessment. The materials for the article were the results of many years of authors' research on various aspects of the methodology for assessing the environmental safety of subsoil use and scientific source analysis. The main research methods were comparison, deduction, analysis, synthesis, and classification. The authors grouped the tools of the strategic environmental assessment into five main groups: analytical, organisational, scientific and technical, control and procedural, and media. Analysis of the legal framework determines the need to finalise the draft of the Subsoil Code to take into account the requirements of the Law of Ukraine “On Strategic Environmental Assessment” in the context of carrying out state examination and assessment of reserves and resources of minerals and establishing conditions for mineral raw materials, drafting industrial development (technological scheme) of the deposit. The classification of the tools of strategic environmental assessment in subsoil use is carried out. Analysis of draft legislation in the field of subsoil use shows positive changes in achieving sustainable development goals. Simultaneously, the authors identified some inconsistencies between different legislative acts and projects.
