Resumo

This paper presents a new approach to exploring bauxite deposits from underground mining works in the bauxitebearing mines of Bešpelj near Jajce in Bosnia and Herzegovina.In the area under consideration, bauxite deposits have been investigated and exploited for over 60 years.Despite the high degree of exploration in the geologically complicated structures of Bešpelj, there are numerous unexplored reserves.Up to now, they have been mainly investigated by drilling from the surface into the borehole network as dictated by legal geological regulations.Due to the increase in depths on which deposits are located and complex structural relationships, such research has become more expensive and less effective.From a geological point of view, the bauxite deposits have developed in the horizontal position.However, longlasting geological evolution from the Upper Cretaceous to the present, has brought deposits in very di erent structural positions.That is why we nd them in an inclined position, in subvertical and vertical, and often in an overturned position.For further research to become rational and e cient, a new approach of study from underground mining works was developed that will serve for study and then for the exploitation of bauxite deposits.
