Abstract
To assess the condition of the instrument array at the Aksu field, the earth's surface has been monitored since 2018. The territory of the mining and technical facilities of the Aksu deposit is characterized by a varying degree of complexity of the relief and a variety of the structure of the composing rocks. At the first stage, instrumental geodetic monitoring was organized to identify active deformations on the object under study using observation profile lines located in the zone of Earth surface movements. Based on the monitoring results, an assessment of the condition of the instrument array of the deposit was carried out and decisions were made on systematic observations of the movement of the Earth's surface using digital aerial photography. A deformation monitoring program has been developed at the site under study, including a project for creating a geometric pattern of signs and a zone of possible and existing deformations has been determined. Aerial photography was carried out with the help of UAVs at intervals every half a year starting in 2020. According to the results of aerial survey, local zones of new deformations on the earth's surface were obtained, as a result of mining underground work at the Aksu mine. Monitoring continues, the next flight of aerial photography is planned for May-June 2022.
