Improving the accuracy of the results of structural mapping of the rock massif in the production additional exploration of mineral deposits is an important task. The actual task in the field of surveying and operational geology is to clarify the position of fracture systems not only within the production block, but also to conduct studies on a part of the field, or on the field as a whole. The use of photogrammetric and GNSS measurement methods allows to create and supplement the geomechanical model of the deposit with information on structural disturbance of the rock massif, obtained during operational additional exploration, promptly and with sufficient accuracy. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.
