Essay

The dissertation is devoted to the substantiation of the technological schemes’ parameters for the anthropogenic coal deposits preparation for their development by using the established dependencies of the anthropogenic coal deposits parameters during their dewatering on the type of biological crops, their density and the geometric dimensions of the planting planting area along the shore. The aim of the work is to establish the dependencies of the processes of dewatering of anthropogenic coal deposits and purification of their liquid phase from fine fractions using bioremediation technology, which will ensure their environmentally safe and efficient extraction and utilization. The scientific significance of the work is the development of mathematical models of liquid filtration processes from an anthropogenic coal deposit in the presence of biotechnogenic impact around the perimeter and on artificial dams built deep into the storage facility from its shores, which allows to calculate the stable position of the water level above a highly concentrated layer of solid particles, depending on the suction capacity, density and distance of green spaces from the water's edge; to improve methods for calculating the parameters of non-pressure movement of liquid with biological cultures floating on a free surface. The practical significance of the work is in the development of recommendations for justifying technological solutions for the dewatering of technogenic coal deposits and preparing them for development in the form of a high-concentration hydro-mixture. The Works also includes the development of mathematical models that allow for determining the rational values ranges for biotechnogenic impact: suction capacity, density, and the distance of green plantings from the water's edge. Additionally, the study develops new methods and technical solutions for preparing technogenic coal deposits for development using bioremediation methods, for which 1 patent has been obtained in Ukraine.
