According to geological data received on the Jakovlevsky deposit, the spatial geomechanical model has been developed. During the analysis of the is intense-deformed condition pictures of distribution of horizontal pressure and vertical displacement on border ore потолочины and карбоновой thicknesses have been received. It is established that the zone of clearing works essentially influences distribution of pressure and movings to border ore roof and carbonic thicknesses. By results of modeling it is possible to estimate possibility of formation  of vertical  water  spending cracks in  an ore roof.
