Description
Блочные щитовые перекрыти дл разработки угольных пластов крутого падени известны.Block shield ceilings for the development of steep coal seams are known.
Особенность описываемого щитового перекрыти в )Ыполнен П} его из отдельных металлических или железобетонных транспортабельных ЖС стких блоков, соединенных между собой шарнирно посредством троса или скоб, что делает блочный HUIT эластичным.The peculiarity of the described panel overlap is c) It is made from individual metal or reinforced concrete transportable living units that are interconnected by means of a cable or brackets, which makes the block HUIT elastic.
Каждый блок состоит из двух (пвеллерных балок /, 2, расположенных параллельно- в одной горизонтальной плоскости, и одной двутавровой балкн 3, смонтированной в середине между ними.Each block consists of two (planer beams /, 2, located parallel to one horizontal plane, and one I-beam, 3, mounted in the middle between them.
Швеллерные и двутавровые балки прикреплены к двум швеллерным профил м и 5, перпендикул рно расположенным к ним с обеих сторон , образу из этих балок металлический каркас пр моугольной формы.Channel and I-beams are attached to two channel profiles, m and 5, which are perpendicular to them on both sides, forming from these beams a metal frame of a rectangular shape.
Дл усилени конструкции блока перпендикул рно балкам проход т два-три ЛЬ са. Ребра жесткости, согто п1ие из швеллерных профилей б.In order to reinforce the construction of the block, two to three beams are perpendicular to the beams. Stiffeners made from channel profiles b.
имеют вырезы, через которые проход т двутаврова балка 3 и швеллерные- /, 2. Концы ребер жесткости, охватыва швеллерный профиль /, 2, изгибаютс с обеих сторон. С верхней стороны металлический каркас наглухо закрыт листовой сталью 7. Лист прикреплен к швеллерным профил м 1, 2 к местах креплени ребер жесткости.have cutouts through which the I-beam 3 and channel-1 pass through. 2. The ends of the ribs, covering the channel profile I, 2, are bent on both sides. On the upper side, the metal frame is tightly closed with sheet steel 7. The sheet is attached to the channel profile m 1, 2 to the points of attachment of stiffeners.
Дл предохранени предзабойного пространства под блочным перекрытием от проникновени породы через зазоры между блоками, каждый лист 7, перекрывающий блок, выводитс на 100 мм за пределы блока. Каждый блок по простиранию равен 0,8 м; вкрест простирани длина блока соответствует мощности пласта , предусмотренного дл отработки за вычетом 0,4-0,5 м.To protect the pre-wellbore space under the block overlap from rock penetration through the gaps between the blocks, each sheet 7 that overlaps the block is output 100 mm outside the block. Each block is 0.8 m along strike; across the span, the length of the block corresponds to the thickness of the formation provided for mining minus 0.4-0.5 m.
Предмет изобретени Блочное щитовое перекрытие дл разработки угольных пластов крутого падени , о т л и ч j ю щ е е с тем, что, с целью экономии материалов и уменьшени трудоемкости монтажных работ, оно выполнено it;t отдельных мета.пл11ческ11Х или железо бетонных транснортабельных жестких блоков, соединенных между собой шарнир о посредством троса или скоб.The subject of the invention is a blocking panel overlap for the development of steep dip coal seams, which is so that, in order to save materials and reduce the labor intensity of the installation work, it is performed; it is t individual meta metaplastic or ferrous concrete. rigid blocks interconnected hinge about by means of a cable or brackets.
