Description
(54) КРЕПЬ СОПРЯЖЕНИЯ ЛАВЫ СО ШТРЕКОМ(54) LAVA STRETCHING STRESS WITH STRETCH
1one
Изобретение относитс к горнодобывающей промышленности и может быть использовано при разработке крутых угольных пластов с применением механизированных крепей .The invention relates to the mining industry and can be used in the development of steep coal seams using mechanized roof supports.
Известна крепь сопр жени , включающа штрековую и надлавную части. Штрекова часть крепи состоит из двух секций, имеющих верхн ки и гидродомкраты перемещени . Надлавна часть также состоит из двух секций, кажда из которых включает лыжу, гидростойки, верхн ки и бортовые щитки. Одна из секций имеет опору с окном, в котором перемещаетс по простиранию опора второй секции надлавной части крепи 1.Known support mating, including the drift and overhead parts. The drift part of the lining consists of two sections having upper and hydraulic jacks of movement. The overhead section also consists of two sections, each of which includes a ski, hydroracks, tops and side shields. One of the sections has a support with a window in which the support of the second section of the overhang part of the support 1 moves along the strike.
Недостатком этой крепи вл етс то, что опора одной из секций надлавной части крепи имеет только продольное окно дл передвижки крепи. Такое соединение опор двух секций требует пр молинейности проведени выработки. Распор секций надлавной части между почкой и кровлей посредством гидростроек, расположенных в один р д и под углом к почве, небезопасен, так как при сн тии распора в борта выработки возможно падение секций крепи.The disadvantage of this support is that the support of one of the sections of the overhang part of the support has only a longitudinal window for shifting the support. Such a combination of supports of two sections requires straightforward development. The expansion of the sections of the overhang between the kidney and the roof by means of hydraulic structures located in one row and at an angle to the soil is unsafe, since with the removal of the thrust into the working side, the support sections may fall.
Наиболее близким техническим решением к изобретению вл етс крепь сопр жени лавы со щтреком, включающа щтрековые и надлавные части, шарнирно соединенные между собой, содержащие гидростойки с опорами, соединенные попарно, траверсы, продольные балки и опорные основани 2. Недостатком такой крепи вл етс то, то опоры гидростоек каждой секции расположены в один р д по простиранию и опираютс на сплощное основание. НаличиеThe closest technical solution to the invention is a lining mating with shchrek, including schtrekovy and nadalnyh parts, pivotally interconnected, containing hydroracks with supports, connected in pairs, traverse, longitudinal beams and support base 2. The disadvantage of such lining is that Then the supports of the hydraulics of each section are located in one row along the strike and are supported on a flat base. Availability
у каждой секции основани , расположенного по простиранию, исключает возможность применени такой крепи сопр жени при обработке крутых пластов механизированными лавами, так как незначительное изменение щирины бермы щтрека в надлавной части требует маневрировани гидростойками в поперечном направлении при сохраненни силовых параметров крепи сопр жени и надежного поддержани кровли выработки.At each section of the base, located along the strike, it excludes the possibility of using such lining mates when machining steep seams with mechanized lavas, since a slight change in the berm width of the berm in the superstructure requires maneuvering with hydraulic posts in the transverse direction while maintaining the strength parameters of lining mats and reliable maintenance of the roof working out.
