Publication in the CUPRUM quarterly

In the last edition of Cuprum Magazines Scientific and Technical Ore Mining the articel, whose co-authors are employees of our company has been released. The article presents the possibility of using the comprehensive interpretation of seismic and geoelectrical methodes in the search and recognition of copper ore deposits.

A number of geophysical methods were used, e.g. 2D reflexive seismics, magnetotellurics and induced polarization (IP), to study the deposit in the Sudeten monocline. This allowed obtaining a morphology of Zechstein [mine stone] thill, tectonic interpretation as well as polarity distribution and deposit zone resistance. The resulting distribution of geophysical parameter anomalies was comprehensively analysed to allow marking ore-bearing body boundaries were found to overlap to a large extent with the boundary of the reductive zone. The polarisation method is very interesting to a deposit researcher, as it uses the ability of sulphide minerals to polarize under an electric impulse. A number of different methodological variants, based on central gradient measurements and using the equatorial system, were tested to select the two most effective for the specific conditions of ore minera-lization. Further research work has been planned on lithological and mineral models as well as in and above mining workings in order to confirm the adequacy of the methods applied in the quantitative assessment of ore mineralisation and mining exploitation planning. Based only on the research now in progress, it is already possible to state that comprehensive geophysical measurements help in works related to search and detection.
