First is cleaned hollow strip adjacent to working from coal fines, barrier pillar is formed in this part of hollow to lead working driving. Sealing of hollow opening is accomplished by making barrier pillar with lead equalling, at least, one cycle of working driving. Filling material is introduced into hollow by means of pipeline in form of inert easily consolidating mass. Barrier pillar is made of rubber tiers laid in row without gaps and filled with working agent. After hollow is passed through with working, working agent is released from tiers, tiers are removed and chock connectors or rubble is placed instead. Barrier pillar is made of netted cylinders filled with expanding concrete-cement composition. Strip is cleaned by hydraulic washout. Hollow is filled in two stages. First, a layer is made whose thickness is not less than width of barrier pillar, and then hollow is filled fully with use of pipelines.
