Rotary drilling rig has bore that is brought to rotary motion by means of motor-reducer, base on which with possibility of turn mechanism for drill displacement is installed, this provides its vertical displacement in long direction. At that mechanism of bore displacement has frame that has telescopic section, vertical stand connected to telescopic section of frame, slide installed with possibility of vertical displacement along guides of stand, drill with motor-reducer are installed on slide, and base is arranged as frame structure placed on supports. Technical result is in increase of accuracy of drilling at simultaneous decrease of dimensions of the unit.
