“…For this, the infinite studied area is divided into a set of finite elements, that is, a continuous function is approximated by a set of piecewise continuous functions. To solve the set tasks, a two-dimensional problem is solved, which takes into account the layered structure of the rock mass, stratigraphy and lithology, geological disturbances, the shape and size of the mined-out space [5][6][7][8].…”
