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...

У овом раду је дат примјер изналажења могућности даљње експлоатације на неком руднику у ситуацији када се у центру експлоатационог поља пронађу природна добра која држава жели да заштити. Примјер методологије ријешавања овакве ситуације је дат на каменолому „Љубачево“ код Бањалуке. Неопходно да се при пројектовању бушачко-минерских радо...
