Annotation:
Experience of the Polish mines on maintenance of workings for reuse is presented. The analysis of clutch joints performance is given. Results of bench tests of racks of strengthening with special structure of various designs are given. The possibility of application of racks of strengthening with high bearing capacity is proved. The design of racks of strengthening from three-element of segments of special shape is offered.
