Analytical research of areas of deformation of rock mass round primary extraction cameras is executed. Areas of these deformations which extend in a massif of ore of lying wall and in a massif of ore of hanging wall at the inclined bottom of cameras are defined. Researches of influence of depth of location of extraction cameras on containing rock mass are executed. It is established, that the deeper extraction cameras are located the broader areas of destroying deformations spread in a rock mass that surrounds cameras. The empirical equations of size of destroying deformations dependence from depth of location of extraction cameras, volume mass of ore and hanging wall soils are received.
