Abstract

The subject of this work is to evaluate methods of the stability of high dumps in the software program Plaxis 2D 2018. The most important and largest dumps in the Czech Republic are located in North Bohemia, Sokolov brown coal basin, specifically in the city Bílina. The dumps are formed as a result of mining and mining activities. The areas created in this way need to be reclaimed by agricultural or other forms of reclamation for further use and needs of society. The thesis on topic „Methods for evaluation of the stability of high dumps“ is focused on the description of the current state of dumps bodies and on the results of own research in the field of the evaluation stability of high dumps. The thesis deals with the development of the solution of the large-volume spatial stress of the deformation state of dump bodies, their specifics and the parameters of the deposited material. The obtained data are then imported into the Plaxis 2D 2018 program, in which geotechnical models of individual phases of the dumps construction are created. The outputs of modeling are stress-strain states, shear strength pumping and the degree of stability created by the construction stages of the hopper storage. The thesis describes and summarizes the stability issues and the author's own research in the field of solving the stability of high dump bodies. The work focuses mainly on the methods of assessing the stability of high dumps, engineering geological survey and monitoring. The results of the own research are also presented. The work is a set of results obtained from laboratory measurements and results obtained from mathematical modeling. Based on these obtained results, there are presented and summarized the recommendations for dumping of dump materials on the dump and methods for evaluation of stability of high dump bodies.
