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...

The Srebrenica orefield is mostly composed of Tertiary dacite-andesites, and quartz latites, pyroclastites, Paleozoic schists, and Quaternary sediments, but in a in a lesser extent. The latest research showed that in the Srebrenica orefield occur complex mineral parageneses and associations deposited in pneumatolytic-hydrothermal and hydrothermal (...

In Bosnia and Herzegovina, Tertiary volcanic rocks occur within two geotectonically different areas: (1) in northeastern Bosnia, the wider area of Srebrenica and, (2) to a lesser extent in central Bosnia, the wider areas of Maglaj, Teslić and Nemila (Kolići). The major and trace element variations in the rocks surrounding Maglaj indicate their high...

World production of pipes is mainly based on the standards of API. However, this does not obligate you to use exclusively for casing manufactured by API standards. The wells that will exploit the hydrocarbons and aggressive media, install the protective casing made of alloy steel not yet covered by API standards. Running casing operation holds a sp...
