Abstract
On the basis of the measurements and computer modeling the dependences of the formation of the expected stresses on the contour of preparatory mine workings have been established. The main regularities of mine workings displacement depending on their location relative to the coal seam are taken into account. Graphs of displacement of roof rocks and soil are given. The questions of stresses redistribution in the vicinity of mine workings are considered and the ways of their stability are determined on the basis of analysis of methods and means of impact on the contour massif.
