    Drainage of coal mine excavation, which consists of deep and surface water drainage is an essential and extremely important technological subject. An effective drainage system guarantees the safety of mining operations. Additionally, drainage system affects the environment therefore we carry out detailed monitoring which enables us to observe achieved results and changes in the hydrogeological and hydrochemical conditions. The article presents the technical progress of construction process of the mine's large pumping stations and pumping of groundwater, which is being continuously carried out by KWB »Bełchatów« professionals. Innovative technical solutions applied in the optimization of pumping systems lead to increased energy efficiency and reduction of the pumping costs. Good cooperation between the pump manufacturers and the mine allows creation of innovative solutions to design high power submersible pump with high energy efficiencies. As a result of the use of submersible OZ pumps pumping systems became fully automated hence they do not require an ongoing service. An energy efficient operation of a new type of pump, which is used in drainage systems of coal mine excavation, can be used successfully in other pumping systems.
