摘要：The paper presents simulation results on gypsum-sand mixtures models. The experiments have been carried out simultaneously in three workings of various configurations in the massif before mine cleaning. They show the differences in the redistribution of rock pressure. The authors have identified the ways to improve the study of rock pressure by developing new modeling methods. These methods make it possible to determine changes in deformations of mining massif from the very beginning and during the entire service life of workings, with the fixation of high rock pressure relief zones and stabilization zones, taking into account the time scale.
