The textbook discusses the issues of determining the stress-strain state (SSS) of rocks during the mining of coal seams. Geomechanical processes occurring during mining operations, as well as technological methods of changing the stress-strain state of rocks, the main methods of ensuring the stability of mine workings in the process of their operation are considered. Classification of mine supports and design schemes for determination of bearing capacity of supports are given. The textbook is intended for university students studying in the direction of training 21.05.04 "Mining" specialization 130404 "Underground development of mineral deposits."
