The paper deals with improving the accuracy of simulation results of geomechanical processes strata movement zones location of construction projects on earth surface at undermining their underground mining. An example of the determination of forecast zones dangerous displacement earth's surface and rock during the resumption of mining stocks ferruginous quartzite. Authors have developed methodological recommendations, which allow defining true physical and mechanical properties of rock massifs on the lab research results of samples and correction factors calculation eliminating properties irrelevance because of massif morphology peculiarities. The results of calculation by the proposed method differ by 6-10% from the actual. Solutions of the authors should be taken into account in the techniques of modeling subsidence and caving rock massifs by maintaining appropriate amendments to the calculated curves that allow establishing the basic parameters of the zones undermining arrays rock underground mining.
