To determine the state of stability of the enclosing dam №1 of the ash dump of «GRES Topar» LLP, a geodetic monitoring project was developed. The methodology of geodetic observations is based on the use of ground-based laser scanning. An observation station was laid on the local section of the dam, which consists of 3 reference points and 5 working reference points. The displacement is determined by calculating the vector distance from the reference point to each working reference point. The vector distance is determined from each reference point in the same way. For control, a total station survey was carried out, made in non-reflective mode. The convergence of the results did not exceed 2 mm. Geodetic monitoring consisted of 3 series of observations. According to the data obtained, the stable condition of the hydraulic structure was revealed.
