- Abstract
Theoretic and experimental research of the mechanical processes occurring during the execution of underground excavations reveal that the installation of the roof support intends to stop the migration of rocks to fill the void created, by creating and involving the 'rock-support' system, shortly after having been executed, in taking over the load. Particularly expressing its specific operation, the interaction mechanism of the support-rock system, accepted by most of the specialists in the field, needs to be correctly explained and assessed, constituting the main argument in forecasting the parameters and the opportunity to use adequate supports considering various conditions and type of rocks. Using and designing therefore the supports depends on a series of factors, some of which, the paper brings forward, analysing their influence on the underground excavation parameters, namely the influence of the digging technology.
