Abstract

Изобретение относитс  к горной промышленности. Целью изобретени   вл етс  снижение затрат на поддержание выработок (В). Позади лавы (Л) 1 смежного столба провод т пластовую В 9 вприсечку к выработанному пространству 4. Из подготовительной В 2 впереди Л 1 бур т скважины 6 на границе с массивом угл  3, противоположной выработанному пространству, перпендикул рно напластованию на всю мощность непосредственной кровли. После чего в них устанавливают стойки 8 органной крепи до контакта с основной кровлей. Стойки 8 обрезают основную кровлю, исключа  ее зависание и разгружа  непосредственную кровлю. После прохода Л 1 подготовительную В 2 погашают. 2 ил.The invention relates to the mining industry. The aim of the invention is to reduce the cost of maintaining workings (B). Behind the lava (L) 1 of the adjacent pillar, a reservoir B 9 is carried along to the developed area 4. From preparatory B 2 ahead of L 1 bore 6 at the border with an array of coal 3 opposite to the developed space, perpendicular to the bedding of the entire thickness of the immediate roof. After that, they install the rack 8 organ lining to contact with the main roof. Racks 8 cut the main roof, excluding its freezing and unloading the immediate roof. After the passage of the L 1 preparatory In 2 repay. 2 Il.
