Description
Предлагаетс способ разработки тонких и маломощных крутопадающих пластов угл без применени крепи в очистном пространстве при безлюдном забое.A method is proposed for developing thin and thin steeply dipping seams of coal without the use of lining in the clearing space during deserted slaughter.
Описываемый способ отличаетс от известных тем, что пройденные до границы блока камеры (печи) закладываютс породой (без выдачи ее на поверхность) от проведени верхней подготовительной выработки. В результате этого породы удерживаютс ненарущенными, чередующимис , полосами угл и породными полосами. Отработка межкамерных целиков угл производитс обратным ходом от границы шахтного пол выемочной машиной с погашением подготоЕ.ительных выработок без присутстви людей в забое.The described method differs from those known in that the chambers (furnaces) passed to the boundary of the block are laid by the rock (without issuing it to the surface) from conducting the upper preparatory development. As a result, rocks are held intact, alternating, coal stripes and rock stripes. The development of intercamera pillars of coal is carried out in a reverse motion from the edge of the mine floor by an excavating machine with the repayment of preparatory workings without the presence of people in the bottomhole.
На чертеже изображена схема осуществлени описываемого способа разработки тонких и маломощных крутопадающих пластов.The drawing shows a diagram of the implementation of the described method of developing thin and low-power steeply dipping layers.
Разработка щахтного пол производитс длинными столбами по простиранию. Этаж нормальной высоты разбивают на два подэтажа высотой 50-60 м. Выемка угл в подэтажах производитс узкими камерами (печами) на всю высоту по восстанию или падению пласта выемочными мащинами, управл емыми дистанционно из штрека. Между узкими камерами (печами) шириной от 1,0 до 2,5 м, в зависимости от устойчивости боковых пород, оставл ютс целики угл шириной от 1,5 до 3,0 м, которые в дальнейщем, обратным ходом, отрабатываютс теми же машинами . Предварительно по пласту проходитс опережающа скважина, котора расшир етс выемочной машиной до требуемого размера камеры (печи). Пробуренные скважины дегазируют пласт, а также служат дл направлени выемочной машины и спуска отбитого угл .The development of the floor is made by long pillars along the strike. A floor of normal height is divided into two sub-floors 50–60 m high. The coal is dredged in the sub-floors by narrow chambers (ovens) to the full height of the uprising or the fall of the seam by excavating mashes remotely controlled from the drift. Between the narrow chambers (furnaces) with a width of 1.0 to 2.5 m, depending on the stability of the lateral rocks, the pillars of coal with a width of 1.5 to 3.0 m are left, which are further processed by the same machines . A preliminary well passes preliminarily through the formation, which is expanded by the excavation machine to the required size of the chamber (furnace). The drilled wells degass the reservoir and also serve to guide the excavation machine and lower the recovered coal.
Последовательна выемка камер (печей) производитс без креплени в направлении границ шахтного пол ; межкамерные целики отра батываютс , наоборот, от границ щахтного пол . По мере выемки камер (печей), последние с отставанием на одну или две камеры (печи) заклаSequential excavation of the chambers (furnaces) is performed without attachment in the direction of the mine floor boundaries; intercamera pillars are repaired, on the contrary, from the borders of the shallow floor. As the chambers (furnaces) are removed, the latter are lagging one or two chambers (furnaces) of the chamber
