This paper analyses the operating condition for the transportation system used in the National Hard Coal Company in Petrosani. This analysis is made for each mine apart and underlines the directions that have to be followed so as to achieve a well-structured revamping that is going to be efficient from an economic point of view. The study of the structure of the transportation systems of mines and their behaviour in time shows an intricate construction of strong arborescent trend. One can conclude that the ratio between the lengths of the transportation routes covered by belt conveyors and the ones covered by scraper conveyors shall have to increase in favor of the former ones.
