n3SUMMARY n3IZVOD
n4This paper presents research results of the relation of execution time of the horizontal development works and rock material strength, as most important parameter of the rock mass. n4U radu su prezentirani rezultati istraživanja odnosa između vremena izrade horizontalnih prostorija i čvrstoće stenskog materijala kao najznačajnijeg parametra stenske mase.
n5Following data were used for execution time evaluation: working cycle and its elements time, working operations time and working cycle operations for executing working operations time output. n5Za ocenu vremena izrade prostorija uzeto je: dužina radnog ciklusa i njegovih elemenata, dužina trajanja radnih operacija i iskorišćenje vremena ciklusa za izvođenje radnih operacija.
n6All the researches were realized in the underground works of the “Trepča” Mining Company, with excavating cross profile (section) of 6,25m2, in 12 different working environments, with compressive strength range between 23 and 123MPa. n6Sva istraživanja su izvršena u podzemnim prostorijama kombinata "Trepča" iskopnog profila 6,25m2 u 12 različitih radnih sredina čija se pritisna čvrstoća kretala od 23 do 123MPa.
n7Analytical (formulas) and graphical (diagrams) dependence between working operations time and compressive strength is determined by the analysis results. n7Analizom dobijenih rezultata ustanovljena je analitička (obrascima) i grafička (dijagramima) zavisnost između parametara vremena trajanja radnih operacija i pritisne čvrstoće stenske mase.
n8Key words: rock mass, compressive strength, development room executing time, and diagrams. n8Ključne reči: stenska masa, pritisna čvrstoća, vreme izrade prostorije i dijagrami
