Creation of digital maps of land disturbed by mining operations

Abstract

This article deals with the determination of the accuracy of creating digital maps of the surface of high-mountain deposits depending on the geological structure of a particular section of the mountain massif and the relief of the area, to develop an experimental method of assessment and control of disturbed by mining operations land using unmanned aerial vehicles (UAV). Experimental studies were carried out by UAV aerial photography with georeferencing to reference points by instrumental measurements. Quantitative dependences on increasing the accuracy of UAV aerial photography due to the relief of the surface of the field in the development of the methodology of UAV application in the conditions of Sulukta brown coal field have been obtained. The results of research will allow to estimate conditions of take-off and landing, to reveal optimum variants of a flight route depending on the set task, optimum variants of overlapping of neighbouring fields by a field of view of a camera on a projection in a horizontal plane taking into account points of turning of UAV, and will increase efficiency of the developed by the authors method of application of UAV in conditions of a complex landscape of high-mountain fields. According to the new received regularities and dependences scientifically determined optimal variants of the flight route depending on the set task, optimal variants of overlapping of the neighbouring fields by the field of view of the camera on the projection in the horizontal plane taking into account the UAV turning points valuable for assessment and control of the disturbed by mining works lands.
