FIELD: mining.
SUBSTANCE: invention refers to mineral resource industry, namely to methods of protection of workings mainly at great depths and flat gradient of thick deposits in worked-out filling area and may be used during selective mining of thick deposits of highly valuable ore minerals. Method includes formation of secondary local zone of unloading by rock pressure in filling mass of worked-out area by means of balance bags and their filling with flexible material. Balance bags are performed during formation of filling mass in area of next working-out and as a flexible material layer of consolidating stowing is used which flexibility is enhanced as compared to the other layers.
EFFECT: improving of stability of workings formed in consolidating stowing mass.
