Abstract: The article deals with the issues of redefinition of the control point coordinates at the Olzherassky open-pit mine of the Kemerovo region, Mezhdurechensk. The most promising method of differential satellite geodetic measurements is used. The results of pre-calculation of errors in the planimetric and elevation coordinates of the control point most distant from the base stations, and their comparison with acceptable values, are presented. The analysis of changes in the control point coordinates for a five-year period is performed. Recommendations are given for updating and improving the survey reference geodesic networks at the open-pit mine in order to increase their accuracy and reliability in the conditions of natural and man-made impacts on open-pit mining.
