Abstract
Disclosed is a method of roadway maintenance. Preliminarily one determines orientation of a system of cleavage fractures in rocks shifted towards the cavity of mine roadway. After reinforcement of support one weakens the locks on the frames of deformed arch support with carrying out breakage of rocks displaced to the cavity of the mine roadway through drilling bore holes and placement of non-explosive destructive substances there. The bore holes are drilled by lines equidistant to the design contour of the mine roadway. After destruction of the rocks deformed frames are dismantled in the contour of the mine roadway, and after collapse of rocks one installs the frame of new support by design contour of the working.
