EXPERIMENTAL AND NUMERICAL METHODS STRESS DETERMINATIONS FOR THE MAIN PARTS OF THE DRILLING EQUIPMENT USED IN DIGGING HORYZONTAL GALLERIES

摘要

Type IMP-2 mobile drilling installations designed at Petrosatti University, patented and manufactured within S.C. UMIROM Petrosani, are used in galleries digging by drilling-blasting technology. These installations are equipped with two manipulators, which support and put into proper position the drill, according to blastholes height and direction. This paper presents the research results monitories in two manipulator main elements: the support aim and the rotation mechanism.by using experimental,analitical and aaalaysis with finit elements.
