Abstract: A brief description and results of laboratory and full-scale tests of the frame support with filling of the behind-anchoring space with backfill material are given in this article. The characteristics are given to the mining and geological conditions at the site where the belt incline is being driven at the Sychevsky I section of the A.D. Ruban Mine (JSC SUEK-Kuzbass). The quality of backfill was tested according to the described technology, the strength characteristics of backfill stone and the degree of influence of the grouting mortar on the surrounding rock massif were determined. It is established that the use of reinforced canvas as a between-frame overlap increases the strength of the backfill stone. Some recommendations on the use of reinforced canvas have been formulated.

Key words: Frame support backfilling behind-anchoring space cementation of the rock massif
