Analysis of the use of unexploited coal resources in liquidated mines: a case study of the Upper Silesian Coal Basin, Poland

Abstract

The reactivation of unexploited coal deposits is complicated and expensive. Profits in the event of success of such a task in liquidated mines would probably only slightly exceed incurred outlays. Nevertheless, when market conditions change, a return to unexploited resources should be considered. Assessment of the possibility of using unexploited hard coal resources in liquidated mines has not yet been scientifically studied, with available literature being concerned only with some general issues of this field. We propose a simple method that informs on the possibility of developing unexploited hard coal resources as a tool to support decision-making processes. The information obtained can be used as a reference point for detailed analysis and multi-criteria evaluation of potentially resources that are ready to use. This method is dedicated to mines that are liquidated. However, after some modifications, the method might also be used by more widely. Given current political and economic circumstances, no attempt is being made to reactivate coal reserves that are left behind. However, it cannot be ruled out that, in the face of a potential energy crisis, changes to the political consensus and climate protection agreements may be considered. In both Europe and Asia, some mines were liquidated according to procedures that did not cut off the possibility of a return to mining – the shafts and part of the infrastructure were protected.
