Impact on hydrosphere and preventive actions

Research indicated the lack of impact of the mine dewatering on the surface water level, particularly in the zone with protected nature areas.
1_445Therefore the lakes in the lakes district are not directly endangered by the mine operation. There are no significant ecological problems associated with remaining hazards as a result of particular care of the facility for environment, compliance with sustainable development principle as well as implementation of Environment Management System according to PN EN ISO 14001 and its maintenance. In case of „Bogdanka” mine, the impact on hydrosphere is associated with drainage of ground water in amount required for correct functioning of the mine. The average annual water inflow to the Mine Lubelski Węgiel „Bogdanka” S.A. amounts about 13 850 m3/ 24h, total average mineralization about 2100 mg/dm3, with ions content of Cl+ SO4 - 807,5 mg/dm3. Owing to their content of ions Cl+ SO4, mine waters are classified in II group – as industrial waters (in accordance with GIG classification) – similarly as in recent years. The mine significantly emphasizes the importance of economical utilization of the waters originating from the rock mass dewatering, and the limitation of Jurassic aquifers drainage in justified cases. A part of mine waters is directly used in the mine for technological purposes, for fire protection systems feeding and for air-conditioning systems as well as on the mine surface, mainly by Zakład Przeróbki Mechanicznej Węgla (Mechanical Coal Processing Facility) in amount of about 380 m3/24h, for water make up in closed circuit in coal cleaning process and by the Company  „Łęczyńska Energetyka” – in amount of about 30m3/24h
Not utilized mine waters (about 13 500 m3/ 24h) are pre-treated in a basin – water settling pond – in form of suspended solids precipitation – prior to their discharge into receiving body i.e. Świnka river. A new water settling pond has been constructed during the period 2002-2004 in order to improve the treatment and discharge conditions for the mine waters. The new pond substituted the previous settling pond located in the form of crater on the waste dump. After water discharge, the crater will be filled with mining waste.

As a pro-ecological project, the new pond was the participant in the National Ecological Competition and our mine won the certificate “Environment Friendly Company” in January 2005. All efforts made the enterprise in order to reduce the impact on environment have been also considered in course of the qualification in framework of aforesaid competition.
