Modernizacja układu pompowania wody w PGG S.A. Oddział KWK „ROW” Ruch Rydułtowy

Artykuł przedstawia proces wprowadzania zmian techniczno-organizacyjnych w obiektach głównego odwadniania KWK „ROW” Ruch Rydułtowy. Podstawową przesłanką ich wdrażania jest ekonomia, czyli całościowe podejście do procesów pompowania wraz z ich optymalizacją oraz poprawa bezpieczeństwa zakładu górniczego. Modernizacja ma ponadto na celu uzyskanie jak najlepszej efektywności, energooszczędności i niezawodności.

Restructuring in the mining industry resulted in a change to the model of the „ROW" mine. Ruch Anna, including main drainage facilities at 500, 700, 800, and 1000 m, as well as a pumping station at 400 m in Ruch Rydułtowy were closed down. The water from the closed-down Ruch Anna was redirected to a district pumping station at 1067 m via a pipeline built for this purpose. The increased water inflow in Ruch Rydułtowy led to the necessity to modernise two main drainage pumping stations at 800 m. Modern substation bays were installed, a pump monitoring, visualisation, and remote control system was launched, as well as modern high-efficiency pumps by Düchting and Powen and permanent magnet motors were used. Both pumping stations were connected hydraulically by adapting pipelines in the Leon II and Leon IV shafts to pump water alternately from the main drainage pumping station at the shafts to the surface. In 2012-2018, these changes made it possible to reduce electricity costs by PLN 6.7 million. In addition, the modernisation of the pumping system allowed the pumping station at 600 m to be converted into a drinking water pumping station, which supplies a surface fire protection system, a processing plant, and the Rydułtowy Heat Plant, where – after treatment – it supplies the district water supply network. What is more, water paths at 600 m were adapted to work as the main fire water tank for mine excavations. Economic benefits depend to a large extent on the efficiency of the pumps and drives used and limitations imposed by intermediate components. The hydrological safety of the mine has been improved by doubling the ability to pump out underground water to the surface and increasing the reliability of electricity supply.
