Abstract
In the presented article, a method of analyzing emergency mine workings for their restoration is proposed. This method is based on the use of underground unmanned aerial vehicles equipped with innovative laser scanning or sensing technologies that allow remote monitoring of areas of rock displacements in the roof at emergency mining sites. The use of this remotely controlled surveying equipment allows you to determine the location and size of dangerous areas of displacement of rocks in the roof. Based on this, with the help of the proposed mathematical model, the values of the normal stress components in the studied displacement regions are established. As a result, if the values of the normal stress components in these displacement areas do not exceed the tensile strength of rocks, then the mining is subject to restoration.
