It is shown that, while transiting from internal dumping to reclamation with creation of natural relief shape, surveying supervision is needed since, according to the adopted technology, it is necessary to reclamate certain shape of relief in certain locations and with given parameters. Since relief reclamation should be performed on great territory, the most rational is to use aerosurveying. In order to reduce cost of the works, it is proposed to perform aerial aerosurveying from unmanned aerial vehicles (UAVs) equipped with digital cameras and GPS equipment. Advantages of the modern aerosurveying equipment and analysis of existing models are presented in this paper, as well as the most suitable for the aerosurveying type of UAV is proposed. It is proposed to perform aerosurveying before and after deposit development. Comparison of images with the help of graphic software complexes allows determining the required volume of works and spatial location of those shapes of relief, which should be reclamated according to the program. In the future, it is proposed to fix positions of axes of long relief shapes with the help of electronic tacheometers and to mark them in the ground by wooden piles with recorded required height of the earthfill. It is further proposed to fix piles along the grid, and length of driving square of the grid should be determined according to the complexity of the relief. It is proposed to separately mark the surface at the stages of mining technical preparation of the surface and laying a potentially fertile layer of rocks. The proposed technology of work allows to achieve the accuracy of reproduction of natural forms of relief about 90 %. Errors in the formation of relief are due to the technical capabilities of mining equipment, which is used for laying rocks.
