Physical and Chemical Geotechnologies

Purpose

Development of decision support system based on simulation results of underworking of surface and selection of rational way of remediation.

Methodology

The studies were carried out by simulating the processes of lowering the earth's surface by it underworking and closing the coal mines by the finite element method. A model was developed for the decision-making algorithm for minimizing environmental and hydro-economic risks when closing mines.

Findings

Were analyzed software products based on finite element methods for modeling the processes of earth surface lowering by it underworking and identified flooding areas in mines closed by the method of wet preservation. The analysis of the basic techniques for calculating the area of lowering of the surface is performed. Has been developed a database of three-dimensional coordinates of coal seam mining for specific mining geological conditions of the Ternovskaya mine JSC "Pavlogradugol". Has been developed a model of an underworked surface with flooding zones, which makes it possible to determine the necessary remediation works and their cost. The results contain studies that were conducted under the project GP-489, which is funded by the Ministry of Education and Science of Ukraine.
