U radu je prikazana metodologija revitalizacije bunara izvedenog u krečnjačkom vodonosniku pod visokim pritiskom na primjeru bunara “CC Well” u izvorištu "Olimpija" Coca-Cola Beverages -Sarajevo. Cilj revitalizacije bio je pretvoriti istražno-eksploatacioni bunar u trajni eksploatacioni vodozahvat koji će omogućiti dugotrajnu eks...

Degazacija (kaptiranje) metana je savremeni način eliminisanja opasnosti od metana i predstavlja kako sigurnosni tako i proizvodni faktor, s obzirom da obezbeđuju nesmetano izvođenje radova eksploatacije upodzemnim rudnicima sa većim izdvajanjem metana . U praksi, tehnologija degazacije zahteva stručno poznavnje rudarskih disciplina kao što ...

Rudnički požari čine relativno čestu pojavu najčešće pri podzemnoj eksploataciji uglja, a ređe u rudnicima metala sa prisustom pirita, i predstavljaju potencijalnu opasnost za zaposlene, instaliranu opremu i uređaje, pa i ceo podzemni proizvodni sistem. Po prirodi nastajanja, rudnički požari su klasifikovani na egzogene koji nastaju spoljnim...

Biodiesel is produced by chemically reacting transesterification of a fat or oil with an alcohol, in the presence of a catalyst. The product of the reaction is a mixture of methyl esters, which are known as biodiesel. Despite its positive qualities, biodiesel has certain negative chemical characteristics when it is used as an alternative fuel. Chie...

Seismicity of an area for a certain period of time, can we understand as a kind of "the forecast" threat of the space seismic intensity. The authors indicate that instumentalni records of earthquake seismology is still not able to give satisfactory answers involving the strong earthquake. Pointed out that neither magnituda and the seismic moment do...
