In order to develop an efficient rock excavation method for hard or super-hard rock formations, a method using the mechanical rock-cutting device combined with thermal action by flame has been experimentally studied.
In this paper, the results obtained in the experiments are presented and discussed. Then, a new idea for the evaluation of the efficiency in the mechanical rock-cuttings in which the thermal action by flame is used at the same time has been proposed.
