Monitoring of quarry slope deformations with the use of satellite positioning technology and unmanned aerial vehicles

In the article we describe the method of arrangement of monitoring of pit slopes deformations, which differs significantly from the traditional (statutory) approaches. We use modern methods of observation: satellite positioning technology and air drones. The original technology of satellite measurements is used to provide control stations, to which subsequently survey points using air drones are connected. Point cloud is optimized leaving the required amount. Irregular filtering is applied, which is the basis for the pit models. Potential danger zones of pit slope, which are compared during observations cycles, are allocated on the basis of modeling of the deformed rock condition. This method allows using digital models of centimeter accuracy. (C) 2017 Published by Elsevier Ltd.
