Description
Сначала штокова полость домкрата 11 .соедин етс со сливной магистралью. При этом рабоча жидкость из напорной магистрали лостзпает в штоковую полость домкрата 12. /J OMKpaT 12, работа на уменьшеиие своей :лины, воздействует на упо,р 10, разворачива , впедр ет его в кровлю и перемещает перекрытие 2 к забою, а также воздействует через т ги стойки 3 на упор 9. Последний, сжима упругий элемент 13, утопает и перемещаетс в направл ющих 14 основани 1 в сторону забо . Рабоча жидкость из штоковой полости домкрата И вытесн етс в силов/ю магистраль под давлением, величина которого зависит от величины требуемого подпора .First, the rod cavity of the jack 11 is connected to the drain line. At the same time, the working fluid from the pressure line closes into the rod end of the jack 12. / J OMKpaT 12, works on its own: lane, acts on the propo, p 10, rotates, penetrates it into the roof and moves the overlap 2 to the bottom, and also acts through the strut of the strut 3 against the anvil 9. Last, compressing the elastic element 13, sinks and moves in the guides 14 of the base 1 towards the bottom. The working fluid from the stock cavity of the jack I is displaced into the force / s main under pressure, the value of which depends on the size of the required backwater.
Затем домкратом 11 аналогично перемеи аетс основание 1 и упор 10.Then the jack 1 similarly moves the base 1 and the stop 10.
Стойки 3 и 4 работают синхронно.Racks 3 and 4 work synchronously.
Предлагаема секци автономно перемещаетс с подпором на забой, причем перекрытие и основание секции перемещаютс раздельно.The proposed section autonomously moves from the backwater to the bottom, with the overlap and the base of the section being moved separately.
Это позвол ет улучшить услови управлени горным давлением в очистных забо х, умепьщить нагрузки на крепь, снизить ее металлоемкость . This makes it possible to improve the conditions of control of rock pressure in the clearing holes, relieve the load on the lining, and reduce its metal intensity.
