Abstract
The problem is to determine the state of the rock mass around the mine according to the data of simultaneous measurement of Cauchy stress vector and displacement vector (Cauchy problem) on its boundary. The overlimiting deformation is taken into consideration. The obtained solution allows estimating the remaining reserve of material strength both on the mine boundary and near it.
