ABSTRACT
The substantiation of the system parameters that most adequately reflect the real mining-geological and mining-engineering conditions of the in-seam workings operation has led to the appearance of an extremely large number of variants of various parameters combinations due to an attempt of their simultaneous accounting. The first stage of testing the model of the “massif – in-seam working” system is the substantiation of its minimum permissible sizes in space, which, on the one hand, allows obtaining reliable calculation results, and on the other hand, saving the computing resource for the required detail of reflecting the system elements peculiarities. The adequacy of modeling the geomechanical processes in the vicinity of in-seam working is of interest, first of all, from the point of view of the degree of influence of the coherence disturbance between rock layers along the planes of laminations on the system SSS.
