Description
До насто щего времени разработка мощных нологих и наклонно-падающих пластов осуществл лась разделением их на слои и обрушением кровли. Однако такой способ не обеспечивает создани щироксго фронта очистных и подготовительных работ.Until now, the development of powerful nologi and inclined-falling layers was carried out by dividing them into layers and collapsing the roof. However, this method does not provide for the creation of a wide front for cleaning and preparatory work.
Дл устранени этого недостатка предлагаетс выемочпое поле по простиранию раздел ть на блоки, в которых выелчка угл производитс последовательно, а направление выемки измен ть в каждом слое.In order to eliminate this drawback, it is proposed to cut a field along the strike into blocks, in which the casting of the coal is carried out sequentially and the direction of the notch is changed in each layer.
На чертеже изображены схемы разработки пласта по предлагаемому способу в разрезе.The drawing shows a diagram of the development of the reservoir according to the proposed method in the section.
Предлагаемый способ основан на разделении пластов на слои и применении металлического перекрыт 1 рабочего пространства, вместо примен емого стоечного креплени . По этому способу пласт разрабатываетс наклонными сло ми 1 толщиной 2,5-3,0 ж в нисход щем пор дке с о брушепием кровли. Первый слой толщиной 2 м отрабатываетс обычной лавой с укладкой на ее почве металлического перекрыти 2 специальной конструкции, а на горизонте вентил ционного щтрека 5- поперечно-наклонным слоем. Остальные слои калсдый толщиной по 2,5 м, отрабатываютс без креплени призабойного пространства под защитой металлического перекрыти 2. Отработка выемочного пол производитс блоками 4 шириной по простиранию 50 м.The proposed method is based on the separation of layers into layers and the use of metal overlapped 1 working space, instead of the rack mount used. According to this method, the formation is developed by inclined layers 1 with a thickness of 2.5-3.0 m in descending order with roof bruzhepy. The first layer, 2 m thick, is processed by a conventional lava with a metal overlay of 2 special designs on its soil, and a 5-transversely inclined layer on the horizon of the ventilation tongue. The remaining layers, each 2.5 m thick, are processed without fixing the bottomhole space under the protection of the metal overlap 2. The excavation floor is worked out in blocks 4 of a 50 m strike width.
Металлическое перекрытие 2 состоит т стальных щвеллерных балок и полос, укладываемых по простиранию через 1,5-2 ж и соединенных между собой канатами (стыки щвеллерных балок располагаютс в шахматном пор дке) и проволочной сеткой, укладываемой поверх щвеллерных балок и стальных полос в два сло .The metal overlap 2 consists of steel steel bar beams and strips laid along strike across 1.5-2 l and interconnected by ropes (the joints of the iron bar beams are arranged in a checkerboard pattern) and wire mesh laid over the steel bar beams and steel strips .
Кроме того, в первом слое на обеих границах панелей по простиранию монтируютс дерев нные щиты 5 по всей длине лавы и поперечно наклонного сло . Эти щиты выполнены из бревен длиной 3-3,5 л которые укладываютс по простиранию и прикрепл ютс к перекрытию при помощи хомутов и канатов.In addition, in the first layer, on both borders of the panels, wooden shields 5 are mounted along the entire length of the lava and transversely inclined layer along the strike. These shields are made of logs of 3-3.5 liters in length which are laid along the strike and attached to the overlap with clamps and ropes.
Выемка угл в сло х производитс на пластах с углом падени 15 буровзрывными работами, а на пластах с углом падени менее 15°-комбайнами . Транспортирование угл вдоль забо производитс на пластах с углом падени 15-20° по эмалированным решеткам, на пластах с углом падени 20-30°-но обычным решеткам и на пластах с углом падени выше 30°-самотеком по почве сло .The excavation of coal in the layers is performed on seams with a dip angle by 15 drilling and blasting operations, and on seams with a dip angle of less than 15 ° with combines. Coal transportation along the bottom is carried out on formations with a dip angle of 15-20 ° along enameled grids, on formations with a dip angle of 20-30 ° but conventional grids and on formations with a dip angle above 30 ° with soil flowers of the layer.
Предлагаемый способ позвол ет также примен ть гидроотбонку с предварительным рыхлением угл ВВ, а также гидротранспорт.The proposed method also makes it possible to apply a hydrotube with preliminary loosening of the explosive coal, as well as hydrotransport.
