FIELD: coal mining industry. SUBSTANCE: method implies cutting drifts, mounting of flexible roofing consisting of two parallel lines which are made up of cylindrical sections. Lines of roofing are connected to each other by rigid links, and placed upon them is metal net. Sections in each line are connected by flexible link at ends. Repositioning of roofing is effected according to extraction of coal from lower lying sub-levels, and it is dismantled in collecting drift. EFFECT: high efficiency. 4 dwg
