Drainage system of mine excavations is one of the most important elements necessary for the correct and safe operation of the mining process. This paper presents innovative solutions adopted in the following areas automation of plunge drainage system, based on the example of »Dębina« salt dome barrier wells; - use of high-power submersible pumps in pumping stations of surface drainage systems. Automations of the environmentally friendly »Dębina« salt dome barrier wells designed and implemented as ring barrier wells, is an example of appropriate approach adopted to optimize the performance of deep wells in relation to hydraulic and energy efficiency. Large drainage, including surface water pumping stations operated in opencast mines, such as PGE KWB Bełchatów SA can be identified as one of the potential applications of submersible pumps. The use of submersible OZ pumps enables automated and energy-efficient operation of new type pumping stations in drainage systems of mine excavations not only limited to extracting lignite.

Postęp techniczny w budowie pompowni w KWB Bełchatów
(Wydawnictwa AGH, 2011) Urbański, Paweł; Latoń, Dariusz
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.
