FIELD: mining engineering.
SUBSTANCE: invention relates to mining engineering and is designed to determine the spatial position of blasting drill holes. A simulator for visual estimation of drill rod position regarding a face consists of a simulated drilling machine comprising a drilling hammer with a drill rod made telescopic to be connectable to the ball end of the ball joint fixed to the plane face attached to the drill hammer with pivot telescopic support connected with the base placed at the top of the drill hammer parallel to the axis of its goniometer equipped with goniometric scale in the form of a semi-circle with an arrow, as well as an indicator of horizontal angles with a linear angular scale thereon, while the simulator is further provided with a holder fixed to the drilling hammer along its longitudinal axis, as well as a ranging mark on a plane face, and the ranging mark and the holder are interconnected with an indicator of horizontal angles and angular linear scale is graduated according to the formula 
EFFECT: invention allows to simplify the design of the device.
