“…Під час складання відповідних звітів ОВД основна увага приділяється питанням поводження з відходами І-ІІІ класів небезпеки. Основним впливом, після земельного відводу земель, вважається дефляція з поверхні техногенних нетоксичних насипів [5,6]. Відвалам розкривних порід характерне інтенсивне самозаростання рослинністю, що обумовлює швидке зменшення пилового навантаження на оточуюче середовище.…”

“…Зміна якості ґрунтів на прилеглих до відвалів розкривних порід територіях обумовлює зміни видового складу рослин та біорізноманіття. Про актуальність дослідження впливу відвалів гранітних кар'єрів на стан прилеглих ґрунтів свідчить зацікавленість науковців цією проблемою [7,8]. Додатковим ускладненням дослідження техногенного навантаження на ґрунти є природна мінливість показників покриву в межах навіть незначних за площею територій.…”

The results of theoretical, field and laboratory studies on the assessment of the impact of the storage of low-hazardous waste from the extractive industry on the quality parameters of the soil cover of the adjacent territories, in particular agricultural land, were analyzed. For this, the granulometric composition, the content of organic substances, mineral nitrogen, and the hydrogen index of salt extraction were determined in soil samples that were taken from the body of the dump, at its foot, and on agricultural land. The analysis of the overburden dump site and adjacent territories showed the feasibility of determining the dust load indicators at the stage of forming environmental impact assessment reports of the planned activity, taking into account the duration of the impact. During the preparation of relevant reports on the assessment of the impact on the environment from the implementation of the planned economic activity, the main attention is paid to the issues of handling waste of I-III hazard classes. The long-term impact of surface deflation of overburden dumps is not sufficiently considered. This is due to their intensive self-healing, and the possibility of the development of suffusion processes and phenomena that will contribute to the periodic opening of the embankment surface is almost not taken into account. These aspects can be taken into account during design through special post-monitoring tasks, on the basis of which additional greening of sanitary and protective zones around man-made embankments should be planned. Questions regarding the formation of protective forest strips or other measures aimed at minimizing the dust load on the territories adjacent to the storage sites of overburden rock dumps are actualized in view of the duration of man-made impact. The identification of previously unforeseeable or insufficiently taken into account impacts and the search for appropriate environmental protection solutions is the task of ecologically responsible enterprises, which corresponds to the principles of the modern environmental management system.

Purpose. The purpose is to reduce mineral losses during the explosive destruction of rocks and environmental pollution by harmful gases and fine particulate matter. Methods. To achieve the objectives of the study, methods of physicochemical analysis and mechanics of continuous media have been used. The method of physico-chemical analysis has been used to determine the quantitative and qualitative characteristics of the composition of the well stemming depending on the parameters of the well, the type of explosive, the amount and type of harmful gases formed during the explosion. Methods of solid medium mechanics have been used to establish the patterns of pressure waves during an explosion depending on the characteristics of the gap filler between the charge and the well wall. To solve the problem of the behavior of a two-layer medium during the loading of a cylindrical cavity by a nonstationary load, a numerical method based on the finite-difference McCormack predictor-corrector scheme has been used. Findings. A resource-saving and environmentally friendly charge structure for rock mining by explosion was developed. The design of the charge involves the formation of a gap between the charge and the wall of the borehole, and filling it with a suspension of calcium hydroxide or a suspension of calcium carbonate. Originality. SThe dependences of the volume of harmful gases (NO2, CO2, CO) formed during the explosive destruction of rocks and the magnitude of the pressure peak in the area close to the charge on the chemical composition of the filler of the radial gap between the charge and the well wall have been set. Practical implications. Developed charge design allows to neutralize the harmful gases formed during the explosion, to reduce the pressure peak in the area of the rock massif close to the charge, and can be widely used in non-metallic quarries that extract minerals for the production of crushed stone.

“…Almost all industries are characterized by the workplace environmental physical factors presence, which negatively affect human health during employment [1][2][3]. Wherein the worst working conditions in the mining industry (coal) [4,5] and in the manufacturing (chemical, metallurgical, mechanical engineering) are observed [6][7][8][9].…”

Purpose: Determination of such an interval of workplace environmental physical factors control, which would ensure high monitoring reliability and the minimum data collection and processing duration (or cost). Design/methodology/approach: To achieve the goal were applied: analysis and synthesis of known scientific results on the topic of research, statistical analysis, mathematical modelling. Statistical data for determining the interval of control was recorded at regular intervals. Findings: A methodology has been developed for determining the interval of workplace environmental physical factors values control. It is based on the identification of patterns of change in the physical factors values. The algorithm of workplace environmental physical factors values control is proposed, which helps to identify cases when the actual values of the factors exceed the limit values. The practical application of theoretical propositions showed that the correlation coefficient between the factual sample and the sample formed using the determined control interval is within 0.74…0.88, which satisfies the condition R > 0.5 as intended. Research limitations/implications: The mechanism for workplace environmental physical factors values monitoring was further developed on the basis of forecasting changes in the physical factors values and determining the duration of the excess of the factors values over the limit. In this study on stationary and conditional stationary processes was the focus. Practical implications: The use of the algorithm that is based on the methodology for determining the interval of workplace environmental physical factors values control contributes to more effective monitoring of working safety. Originality/value: For the first time justified by the choice of the control interval of workplace environmental physical factors values with acceptable accuracy of the forecast that allow to quickly establish working conditions hazard class.
