The issue of using unmanned aerial vehicles for geomechanical monitoring of the state of a rock mass near a developed quarry space is investigated. An example of the implementation of a methodology for assessing rock displacements in a deep quarry using unmanned aerial vehicles is given, a series of surfaces are processed in the ASNI Cloud 3D program, quantitative and qualitative characteristics of rock displacement in the area of a large collapse of the eastern side of the quarry are given. Based on the research results, it is concluded that the use of unmanned aerial vehicles in conjunction with the ASNI Cloud 3D program for operational monitoring of rock mass displacements is economically promising, which will speed up and simplify the procedure for creating digital models with the necessary degree of detail for designing variants of the mining development plan.
