Description
Системы разработки мощных крутопадающих пластов наклонными сло ми с обрушением налегающих пород в нисход щем пор дке известны .Development systems for high-powered steeply dipping seams by inclined layers with overburden collapse are known in descending order.
Онисываема система отличаетс тем, что нласт разрабатываетс наклонными сло ми с оставлением в кровле каждого сло толщи угл , котора отрабатываетс путем обрушени участками в направлении сверху вниз с выпуском угл в призабойное пространство нижележащего сло , а также тем, что очистные работы верхнего сло ведутс с опережением по отношению к нижележащему слою. Такое выполнение системы разработки обеспечивает увеличение производительности работ.An onsiputable system is characterized in that the nlast is developed by inclined layers, leaving a layer of coal in the roof of each layer, which is worked out by breaking the sections from top to bottom with the release of coal into the bottom hole space of the underlying layer, as well as in the cleaning of the upper layer ahead of time in relation to the underlying layer. This implementation of the development system provides increased productivity.
На фиг. 1 показана схема разработки пласта описываемой системой и детали узлов Л и Б; на фиг. 2 - схема отработки толщи угл .FIG. 1 shows the scheme of reservoir development by the described system and details of the nodes L and B; in fig. 2 - scheme of mining coal.
Пласт разрабатываетс наклонными сло ми в нисход щем пор дке с обрушением налегающих пород. Слои вынимаютс обычным способом. Работы по выемке верхнего сло / (фиг. 1) ведутс с опережением по отношению к нижележащему слою 2. В кровле каждого сло оставл етс толща угл 5 мощностью 2-3 ж (фиг. 2). Толща угл вынимаетс участками длиной около 7 м по восстанию путем принудительного обрушени или самообрушени с использованием горного давлени в направлении све;рху вниз. Перед обрушением в нижней части Обрушаемого участка возводитс посадочный полок 4. После этого на полке образуют подушку угл 0,5-1,0 м, убирают костры в обрущаемом участке и пробуривают р д шпуров 5. После взрывани шнуров толща угл обрушаетс и уголь выпускаетс через окно, разделанное в посадочном полке 4, в призабойное пространство 6 нижележащего сло . Затем после выпуска угл производитс обрушение налегающих пород.The reservoir is developed in oblique layers in descending order with overburden collapse. Layers are removed in the usual way. The excavation of the upper layer (Fig. 1) is carried out ahead of the underlying layer 2. At the top of each layer there is a thickness of coal 5 with a thickness of 2–3 g (Fig. 2). The coal is removed in sections of about 7 m in length by uprising by forcible collapse or self-destruction using rock pressure in the direction of the line downwards. Before the collapse, planting shelves 4 are erected in the lower part of the section to be broken. After that, a cushion of 0.5-1.0 m is formed on the shelf, fires are removed in the section to be cleared and a series of holes are drilled 5. After the cords are blown, the coal is collapsed and coal is discharged through a window, cut in the landing shelf 4, in the bottomhole space 6 of the underlying layer. Then, after the release of the coal, overlapping rocks are produced.
