Abstract. The results of the testing of the experimental method of the roadway maintenance with cablebolts at plow seam extraction in conditions of weak rocks are presented. The research methodologies of the deformation of the rock massif around roadway and displacement of support elements are presented. The advantage of geometric leveling of contour and deep-seated anchors on observation stations is shown. The comparison of the effectiveness of an experimental method for maintaining the roadway with cablebolts against the "classical" methods dictated by the existing regulations for mines Ukraine is made. The advantages of the usage of cablebolts are shown. The regularities of the rock massif deformation in the area of abutment pressure and behind the lonwall face are determined. The parameters of roadway support reinforcement for effective roadway maintenance at every stage with minimal losses of cross section are substantiated.

Key words: mine working maintenance, cablebolts, weak rocks, massif deformation.
