FIELD: mining.
SUBSTANCE: invention relates to mining and intended for explosive blast holes spatial position determining. This is achieved by fact, that simulator for determining of blast holes direction drilled relative to rock face plane consists of plate with angular scale, drilling machine simulator, including drilling hammer with drilling rod, made telescopic with possibility of connection with ball hinge ball pivot, fixed on rock face plane, connected to base telescopic support pivotally attached to drilling hammer, as well as casing arranged on drilling hammer upper platform, provided with light source and deflection scale in form of semicircle with plumb bob, wherein axes of light source, drilling hammer and drill rod are located in one vertical plane. According to invention, plate is made flat and installed in parallel to rock face plane, and angular scale, arranged on plate, is calibrated by formula 
where Lβ is angular scale section length measured from mark 90° on angular scale, corresponding horizontal angle value of β; L is distance between plate with angular scale and ball hinge; β is value of horizontal angle, degrees; besides, simulator is equipped with second plate, mounted perpendicular to rock face plane, simulating mine side wall.
EFFECT: technical result is simplification of device design, as well as reduction of operation labor input during training of blast holes drilling direction visual determination skills.
