(54) СПОСОБ КРЕПЛЕНИЯ ОЧИСТНОЙ ВЫРАБОТКИ МЕХАНИЗИРОВАННОЙ КРЕПЬЮ,РАЗДЕЛЕННОЙ НА ГРУППЫ, С ГИБКИМ ПЕРЕКРЫТИЕМ У КРОВЛИ(54) METHOD FOR MOUNTING THE CLEANING DEVELOPMENT OF A MECHANIZED CREW DIVIDED IN GROUPS WITH A FLEXIBLE COVER
На перекрыти х каждой секций 5-7 крепи установлены призабойные поворотные консоли 3/ прижимаемые к кровле домкратами 4.On the ceilings of each sections 5-7, bottom-hole rotary consoles 3 / pressed to the roof with jacks 4 are installed.
Способ креплени очистной выработки механизированной крепью, разделенной на группы, с гибким перекрытием у кровли осуществл ют следующим образом .The method of fastening the cleaning development by mechanized support, divided into groups, with flexible overlapping at the roof is carried out as follows.
Перед выемкой угл комбайном гибкое перекрытие 1, поступающее в забой в виде рулона,раскатывают и подвешивают , соедин с ранее установленными посредством скоб 2, В процессе выемки угл вслед за комбайном включают домкрат 4, и гибкое перекрытие .1 поворотной консоли 3 прижимаетс к кровле без сн ти распора и передвижени секций крепи. После возведени перекрыти снимаетс распор и производитс перемещение секций 5 крепи, не имеющих призабойных поворотных консолей 3. Секции б крепи, снабженные призабойными поворотными консол ми, перемещаютс к забою после перемещени смежных с ними секций, причем перед передвижкой домкрат 4 сокращаетс , и поворотна консоль 3 отводитс от кровли.Before the coal is dredged by a combine, a flexible overlap 1, which enters the face in the form of a roll, is rolled and suspended, connected to the previously installed brackets 2. remove thrust and movement of the support sections. After erection, the strut is removed and the sections 5 of the lining, which do not have bottom-hole rotary consoles 3, are moved. retracted from the roof.
Применение предлагаемого способа позволит повысить эффективность поддержани слабых кровель, снизить трудоемкость креплени , увеличить скорость подвигани забо .The application of the proposed method will make it possible to increase the efficiency of maintaining weak roofs, reduce the labor intensity of fixing, and increase the speed of advancement of the bottom.
