FIELD: mining.
SUBSTANCE: invention relates to mining and is intended for determination of spatial position of blast holes. Simulator of the eye position spatial measurement of the drilled bore pits comprises a drilling machine simulator including a drilling hammer with a drill rod. Rod is made telescopic with possibility of connection with spherical ball joint hinge. Hinge is fixed on the bottomhole plane and is hinged to the drilling hammer. Telescopic support is hinged to the drilling hammer and connected to the base. At the upper platform of the drilling hammer coaxial to it there is a casing equipped with an angle scale in the form of a semicircle with a plumb. To the surface of the casing perpendicular to the plane of the circular angular scale there attached is an arrester by means of a coupling, with possibility of rotation around the coupling axis. Marking of scale of axle is oriented in direction of ball hinge. Pusher is equipped with centering weight. All elements of the device, except arrow of the cap, are made from non-magnetic material.
EFFECT: simplified design of the device and reduced labor input during training of drillers.
