TECHNOLOGICAL EFFECTS OF EXPLOSION DUMPS STORAGE ON DEVELOPMENT OF AGRO-ECOSYSTEMS

Abstract

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.
