AB: Geophysical Center of Tirana has carried out some experimental site work within the domain of questions related to cavities occurred in the mined and abandoned mines in Albania. Artificial cavities represent an important research target in environmental mining. In our choice of geophysical methodologies, we have applied tomography resistivity and self-potential field method. If we consider the geological environments, each method is rare or less effective but in practice we have to resolve difficult ambiguity problems in the interpretation of geophysical data. Resistivity measurements have shed light on a low or high resistivity structure, of which characteristics coincide with the established geometry of the cavities. These are interesting examples to map cavities within a geological formation bedrock. The aim is to test with 2D electric imaging method, the cavities filled with air or soil. As regards the sources of the SP anomalies in the test sites above a "cavity effect" in some cases is observed the SP potential anomaly distribution. Our test coincide in three areas where are present the problems connected with ex-mining in Albania and the results are presented for each region separately.
