Abstract

The results of mathematical modeling of working excavations while mining out coal layers in one of the fields of the Kuznetsk coal-mining field are presented in the paper. Engineering-geological features of the coal-measure rocks, plan and mutual orientation in the space of working excavations are considered. Evaluation of the stress state of coal-measure rocks in the main stresses is given. Features of formation of stress fields under the mutual influence of working excavations in the period of 2016-2018 are given.
