Description
подт гивани устройства к механизированной крепи 8 очистного забо предусмотрены гидродомкраты 9. Дл упрочнени уложенной в полосу породы в штреке 10 устанавливают насос 11, а на крепи 12 закрепл ют опалубку 13. Дл получени забутовочной породы в выработанном пространстве подрывают часть кровли 14.hydraulic jacks 9 are provided for tightening the device to the mechanized lining 8 of the clearing downhole. To strengthen the rock laid in the strip, a pump 11 is installed in the drift 10, and a formwork 13 is fixed to the lining 12.
Способ возведени бутовой полосы осу-, ществл етс следующим образом.The method for erecting a rubble strip is carried out as follows.
Обуривают часть кровли 14 и взрывают ее над перекрытием 3, установленным в наклонном положении П. При этом отбита порода скатываетс под действием собственной массы по наклонному перекрытию 3 - место укладки бутовой полосы. После этого включают гидродомкраты 5-7 и производ т зат гивание породы в бутовую полосу и ее уплотнение в пространстве, ограниченном- , с одной стороны перекрытием 3, установленным в вертикальное положение I, а с другой стороны - крепью. 12 штрека с опалубкой 13. Затем в уплотненную массу породы закачивают посредством насоса 11 закрепл ющий раствор, например на карбамидной или цементной основе, после чего устройство подт гивают с помощью гидродомкратов 9 к мехкрепи 8 на новую заходку и цикл работ по возведению очередного участка бутовой полосы повтор етс .A portion of the roof 14 is obsessed and blown over the overlap 3 installed in the inclined position P. At the same time, the rock is beaten down by the action of its own weight along the inclined overlap 3 - the place where the quarry strip is laid. After that, hydraulic jacks 5–7 are turned on and rock is pulled into the rubble strip and compacted in a space limited by, on the one hand, overlapping 3, installed in the vertical position I, and on the other side - with a bolt. 12 drift with formwork 13. Then, a fixing solution is pumped into the compacted rock by means of a pump 11, for example, on a urea or cement base, after which the device is pulled using hydraulic jacks 9 to the fastener 8 to a new entry and cycle repeats.
