Qualitative characteristics of bauxite deposit „Oštrelj“ are defined through extensive laboratory testing of chemical and mineralogical-petrographic composition, and geomechanical characteristics. Chemical composition has shown that it is a relative poor bauxite with low Al/Si module (2,28). Low values of Al/Si module are result of lower Al2O3 conc...

This paper presents the results of the calculation of coal reserves obtained by classical method (calculation method of geological blocks), which were compared with the results obtained by the calculation using software. Since this area was explored for long period of time and elaborates were done in past, we came to an idea to compare results from...
