The aim of presented research is to develop methods of determining the parameters of rational control of machine operation of percussion drilling during its operation in geological and mining conditions defined. To set the goal of empirical research, it is based on the literature search in which several researchers have studied the mode of percussion drilling with different methods based on the physic mechanical properties of the rock, setting parameters of the machine, geometric parameters of tool. The literature has shown us that there are now some methods of determining the dependencies of the drilling speed, and height of penetration is a function of the energy of a piston stroke and the drilling speed is a function of the height of penetration into the rock and the rotational speed, The analysis shows that these methods are based on knowledge of the peculiarities of the interaction of the tool against the rock. Each time, we take into account the parameters mentioned above. Keywords-Forces applied, properties of the rock, progress drilling, the height of penetration.
