Mine closure is the final specific stage of its lifetime. Deep mines hydrogeology is of special importance when closing the mines. Important expertise has been gained in Murmansk region in water-related issues. The redistribution of tectonic and gravity stresses in the rock mass should be taken into consideration too. Dynamic occurrence of stress-strain host rock mass has been often observed during open pit mining. All these factors should be taken into account when preparing the walls for semi permanent or permanent mine closure. Solid mining and geological information on deep open pits is required to be used for mine closure.
