| n3 | Abstract: | n3 | Sažetak: |
| n4 | New method of drilling narrow vertical boreholes by controlled hydrogen combustion assumes that rocks melt and around thermally strained rock form radial fractures under high temperatures and pressures at interaction of the rock and the flame. | n4 | Nova metoda bušenja uskih vertikalnih bušotina kontrolisanim sagorevanjem hidrogena podrazumeva da se stene tope i da se oko termički izobličene stene stvaraju radijalne frakture na visokim temperaturama i pritiscima pri interakciji stene i plamena. |
| n5 | To verify the range of formed radial fractures in different rock types, it is needed to know in detail rock and mineral properties before and after melting process of the rock. | n5 | Da bi se proverio opseg formiranih fraktura u različitim vrstama stene, potrebno je detaljno poznavati svojstva stene i minerala pre i nakon procesa topljenja stene. |
| n6 | Petrographical, mineralogical, chemical and physical properties of rock samples were studied to have thorough knowledge of rock attributes. | n6 | Proučavane su petrografska, mineraloška, hemijska i fizička svojstva uzoraka stene kako bi se podrobnije upoznala svojstva stene. |
| n7 | Results of this complex rock analysis represent the basis for physical and mathematical modeling of viscous properties of melt of selected rocks and for modeling of radial fractures in the rocks during narrow vertical borehole drilling process. | n7 | Rezultati ove složene analize stene predstavljaju osnovu za fizičko i matematičko modeliranje viskoznih osobina rastopa odabranih stena i za modeliranje radijalnih fraktura u stenama pri procesu bušenja uskih vertikalnih bušotina. |
| n8 | Key words: rock properties, drilling, fracture, melt, penetration | n8 | Ključne reči: osobine stena, bušenje, pukotina, rastop, prodiranje |
