Abstract
Based on the analysis of mining and geological conditions of the Eastern Donbass offered a method of determining the value of the expected displacement of the contour of preparatory workings depending on their location relative to the excavation work. The graphs of displacement of roof rocks, changes of displacements of rocks in front and behind the face depending on the different resistance of the lining are given. Considered the formation of zones of broken rocks in the vicinity of mine workings and identified ways to ensure their stability.
