Maintenance of the dewatering regions of liquidated mines has a yearly cost exceeding $50 million. The results of research and forecasts conducted allow us to state that, in the dewatering plants operating in the Upper-Silesian Coal Basin, there are possibilities of reducing the general costs by 17% in the perspective up to the year 2030. However, this requires introducing the following changes and modifications: transforming some parts of stationary pumps into deep-well ones while taking into consideration the hydro-ecological restrictions; shortening the longwalls in the stationary pumps; and directing some of the pumped water to the operational mines that neighbor the longwalls of the liquidated mines. The changes presented should mostly be used in order to rationalize the costs of dewatering while maintaining the currently existing package of ecological and social benefits. These benefits are: the minimization of water hazards in the neighboring operating hard coal mines, and the protection of work places in the existing dewatering plants.
