Abstract
An analysis of existing scientific works shows that the adequacy of mathematical models of the stress-strain state for rock masses largely depends on the accuracy of the determined components of the natural stress field. In the present article, a new algorithm is proposed that increases the accuracy of the values of the natural stress field in coal-bearing rock masses. This algorithm is based on the following procedure. First, the parameters included in the corresponding mathematical models are determined. Then, using this set of mathematical models, a set of values for the tensor of the natural stress field is calculated. Finally, using the method of successive approximations, the value of the natural stress field that most accurately describes the state of the researched section of the rock mass is determined. The use of the developed algorithm as part of the mathematical support in automated control systems used in the coal industry will improve the productivity and safety of mining.
