Abstract
In the article the calculation method of finite elements is used to analyze, monitor and forecast the stressstrain state of the rock massif when mining iron ore by underground methods. There are determined stress fields and strains around the dead area of empty and backfilled stopes. Also, isolines of maximum stresses σ1 in control points of empty stopes and those with backfilled dead areas are provided. There are determined new dependencies of the value of maximum vertical strains of the daylight surface in the control points of the rock massif for various physical and mechanical properties of rocks.
