FIELD: mining engineering.
SUBSTANCE: invention relates to mining engineering and is designed to determine the spatial position of blasting drill holes. There is proposed a simulator for estimation of directions of penetrated drill holes relative to the plane of the face consisting of a plate in the form of an arc with an angular scale, simulator of drilling machine comprising a drilling hammer with a telescopic support, telescopic drill rod adapted to be connected to the ball end of a ball joint fixed on the face plane, and a light source connected with the drilling hammer being located in the same vertical plane of the axis of the light source, a hammer drill, a drill rod and a ball joint. And a light source is disposed coaxially with the drill rod, a plate is equipped with telescopic uprights, consisting of cylinders with rods, with metric ruler placed on rods, and the goniometric scale is placed on a plate and graduated according to the mathematical expression provided.
EFFECT: proposed design of the device provides increased accuracy in determining angles of vertical drill holes and reduces the labour intensity at training drillers' skills for visual determination of the direction of drilling holes.
