Abstract: The realization of holes in open mine exploitation can be carried out in three different ways: Percussive drilling (out/bottom of the hole), Rotary drilling (with tri-cone) and rotary Drilling (cutting). According to the method employed, the mechanism of rock destruction differs. The principle remains the transmission of energy coming from a drilling jumbo to a tool intended to destroy rocks. In practice, it is very difficult to regulate the push being given the means available. Generally the only indication is given by a pressure gauge installed on the feeding circuit, that makes its value very delicate to optimize. The main object of this research is to put in obviousness experiments and by validation on site, the evaluation of the optimal parameters for a rotary drilling machine.
