Researches of parameters influencing on mine working driving intensity and rational organization of building have been conducted. It is shown that the productivity of drilling tools which allows providing required speed of mine working driving increases as far as duration of building of horizon of the second stage of opening reduces, thus the drilling productivity dependence on time of horizon building can be described by a power function.
