FIELD: mining.
SUBSTANCE: connecting survey method is implemented in the following way: one downward shaft scanning travel determines a) plane coordinates (X, Y) of one and/or more points of the surveying underground network in the coordinate system accepted on the surface; b) orientation of underground horizons - transfer of direction angle from surface to the well; c) absolute height point (Z coordinate) of points of underground surveying network in mine workings in the coordinate system which is common with the surface.
EFFECT: improvement of prompt transfer of the specified coordinates and direction angle from day surface to underground mine workings at maintaining high accuracy.
