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...

Seizmičko opterećenje djelovanjem na građevinsku skelu slobodnog sastava – fasadna skela – predstavlja vid incidentnog dešavanja. Opasnosti i štetnosti, te mjere zaštite građevinskih radnika koje izvode fasadne radove na predmetnom objektu pri korištenju date skele su evidentne. Zato, potebno je sa dužnom paž...

Disposed of in the open air coal is constantly in contact with oxygen from the air, which leads to oxidation of coal in this matter and is released a certain amount of heat. If there are no conditions to the constant heat sinks, warming occurs, then the only inflammatory coal matter. The tendency of matter to carbon just warming up and only inflamm...

Underground exploation coal is performance in natural environment in wich provoke change, prevalent negative on environment. From our and foreign practice undergrounde exploatation coal is evidence influence up on air, water, land and facilities and surrounding live world. Following and systematic records of change is obvious damage effect, which m...
