Abstract
Изобретение относитс к горному делу и позвол ет упростить технологию усилени крепи за линией очистного забо . Способ включает возведение рам 5 металлической крепи, состо щих из установленных со стороны отработки лавы и массива стоек 2 и соединенных со стойками 2 узлами податливости верхн ков (В). Концы В со стороны отработки лавы соедин ют прогоном 8. Под ним между смежными В устанавливают общие стойки 7. По мере продви- гани очистного забо под прогоном 8 устанавливают органную крепь. После продвигани лавы стойки 7 убирают . 3 ил. б (ЛThe invention relates to mining and makes it possible to simplify the technology of strengthening the support behind the clearing line. The method includes the erection of metal support frames 5, consisting of the racks 2 installed on the side of the working of the lava and the massif and connected to the racks with 2 nodes of flexibility of the tops (B). The ends B from the side of mining the lava are connected by a pass 8. Underneath, common racks 7 are installed between adjacent B. As the clearing face progresses, a body support is installed under pass 8. After advancing the lava rack 7 is removed. 3 il. b (L

Изобретение относитс к горному делу, в частности к способам креплени выемочных выработок при бесцели- ковой технологии отработки угольных пластов.The invention relates to mining, in particular, to methods for securing excavation workings in the purposeless technology of mining coal seams.
Целью изобретени вл етс упрощение технологии усилени крепи за линией очистного забо .The aim of the invention is to simplify the technology of reinforcement of the support behind the line of the cleaning slab.
На фиг.1 показано поддержание выработки , вид в плане; на фиг.2 -разрез А-А на фиг,1; на фиг.З - узел I на фиг.2,Figure 1 shows the maintenance of development, a view in plan; in Fig.2 is a section A-A in Fig, 1; fig.Z - node I in figure 2,
Крепление выемочной выработки 1 производ т в следующей последовательности . Стойки 2 устанавливают со стороны массива 3 и скрепл ют их боковыми ст жками 4 с ранее установленной рамой 5. Затем в пространстве между стойками 2 со стороны отработки лавы 6 став т стойку 7 под ранее установленный прогон 8. Верхн ки 9 поднимают под кровлю выработки 1 и фиксируют в заданном положении на стойках 2, причем концы верхн ков 9, обращенные к стороне отработки лавы 6, скрепл ют хомутами 10 с прогоном 8. Рамы заклинивают, производ т зат жку кровли и боков межрамным ограждением , закрепленное пространство забучивают.The fixing of the excavation production 1 is carried out in the following sequence. Racks 2 are installed on the side of array 3 and fasten them with lateral gates 4 with the previously installed frame 5. Then, in the space between the racks 2 on the side of mining of the lava 6, stand 7 are installed under the previously installed girder 8. Upper 9 are raised under the roof of the mine 1 and fixed in a predetermined position on the uprights 2, with the ends of the tops 9 facing the side of the working out of the lava 6 fastened with clamps 10 to the purlin 8. The frames are wedged, the roof and sides are tightened with the interframe barrier, the fixed space is forgotten.

По мере подвигани лавы, за сопр жением 11,вслед за передвижкой лавного конвейера 12 к груди очистного забо 13 дл усилени крепи и охраны выработки 1 со стороны выработанного пространства производ т пробивку органного р да 14 под прогон 8, а затем по мере продвигани лавы стойки 7 убирают.As the lava moves, at mating 11, following the movement of the laval conveyor 12 to the chest of the clearing hole 13, in order to strengthen the lining and protect the mine 1 from the developed space, an organ row 14 is punched under run 8, and then as the lava moves 7 clean.
