Czynne wyrobiska odkrywkowe surowców węglanowych na tle granic GZWP a możliwości ich rekultywacji przez wypełnianie odpadami
Abstract
Active opencast excavations of carbonate raw materials in relation to MGB area and the possibility of their reclamation by filling with waste.
A b s t r a c t . Mining companies that own opencast excavations with the prospect of future reclamation, may constitute a serious consumer group for gangue (mining waste) from coal mining and other groups of waste. The aim of the study is to identify the location of active opencast mining excavations of carbonate raw materials in relation to the boudaries of the Main Groundwater Basin (MGB) in Poland. The exploited excavations of carbonate raw materials are located in the southern Polish provinces (Dolnośląskie, Lubelskie, Łódzkie, Małopolskie, Opolskie, Podkarpackie, Śląskie and Świętokrzyskie voivodships) and are located on the map of the MGB boundaries prepared by PSH PIG-PIB. As a result it was found that 29 of the 66 pits are located within the designated MGB areas, which represents about 44% of the total area. In such areas, proper selection of wastes is a very important issue because of their quality and possible changes in chemical composition over time.
