Použití injektážních směsí v rámci řešení útlumu probíhajícího endogenního hoření deponovaného těžebního odpadu

Abstract

In this bachelor thesis, the author deals with the issue of the use of grouting mixtures in the rehabilitation of tailings created by the deposition of mining waste, mainly in connection with the need to dampen the ongoing thermal activity. The aim of the thesis is to analyse and evaluate the possibilities of using grouting mixtures for limiting or completely suppressing combustion in coal spoil heaps. In the theoretical part of the thesis, the author introduces the principles and causes of thermal activity in coal refuse dumps and the use of injection mixtures abroad and in the Czech Republic. The author also pays attention to the classification and properties of individual types of injection mixtures applied in the rehabilitation of burning tailings. The technical part of the bachelor thesis consists of a verification test of selected grouting mixtures. The thesis concludes with an evaluation of the suitability of the used mixtures in terms of technical efficiency and the possibility of practical deployment in real conditions.
