The analysis of bedrock properties affected the in-site acid leaching technology for uranium mining site
Original language description
The paper continues to issue result of site investigation and laboratory tests for properties of fucoid sandstones in the north-western part of the Czech Republic, near Stráž pod Ralskem. This site was mainly contaminated by almost 5 million tonnes of sulphuric acid and other chemicals injected over 32 years. There are 186 million m3 of contaminated water in the Cenomanian aquifer, caused by a reaction between the acids and the rock. All this contaminated ground water is concentrated in the area of 24 km2. Diamo has started detailed laboratory tests of fucoid sandstones layer since 2005 and aquifer test has started for the same layer since 2008. The data from these activities are available and were used for the analysis. The first part of the paper isfosuced on analysis of pumping test which was realised in 2009 by empirical equations. In the second part is shown example of large scale analysis by created numerical model.
