Abstract

The publication analyses the possibility of reducing the costs of mine liquidation in terms of obtaining methane from goafs. Obtaining methane from goafs can bring financial, ecological and social benefits for many years. In areas where mining activity is reduced, any potential way to restore workplaces should be considered. The possible variants of technical solutions were presented and the conclusions resulting from each variant were indicated. Optimal variants were selected from the proposed liquidation variants by means of single-criterion and multi-criteria analysis. The analysis showed the main factors influencing the course of the mine liquidation and methane drainage process.
