FIELD: mining.
SUBSTANCE: eye estimation simulator for determining drill rig position towards face plane consists of a plate with angular scale, drill rig simulator, comprising drill hammer with telescopic drill rod, which allows connecting the ball pivot of the ball joint fixed to face plane, telescopic support hingely connected to drill hammer connected with the base, as well as a cover provided at the top of the drill hammer, equipped with light source and angular scale in form of semicircle with a plumb. The light source is perpendicular to the drill hammer axis, the plate is flat and installed perpendicular to the face plane, and the angular scale placed on the plate is graduated by the formula:
,
where Lβ - length of the angular scale segment measured from face plane, corresponding to horizontal angle valueβ; Lst is the length from the ball joint to the light source axis; L is the length from the ball joint to the plate with angular scale; β - the value of the horizontal angle, deg.
EFFECT: simplified design.
