Description
Изобретение относитс к горной промьошленности и может быть использовано при разработке пологих пластов полезных ископаемыхf например калийных солей, при наличии в пласте просло породы.The invention relates to mining and can be used in the development of flat seams of minerals, such as potassium salts, in the presence of rock formation in the formation.
Известен способ разработки пологих пластов полезных ископаемых сложного строени , включающий селек тивную отработку полезного ископаемого и породного просло с размещением породы от него в выработанном пространстве 1.The known method of developing flat seams of minerals of a complex structure, including selective mining of mineral and rock spill with the placement of the rock from it in the developed space 1.
Однако данный способ недостаточно эффективен.However, this method is not effective enough.
ОABOUT
Известен также способ разработки пологих пластов полезных ископаемых , включающий бесцеликовую отработку выемочных столбов длинными очистными забо ми с управлением кровлей полным o6pi eHHeM и транспортированием полезного ископаемого по, выработкам 2 .There is also known a method of developing flat seams of minerals, including aimless mining of excavation pillars with long clearing faces, with roof management complete o6pi eHHeM and transportation of mineral resources by mines 2.
Однако такой способ недостаточно эффективен при разработке пластов сложного строени .However, this method is not sufficiently effective in the development of layers of complex structure.
Целью изобретени вл етс повышение эффективности отработки пластов с породным.прослоем.The aim of the invention is to increase the efficiency of mining of rock formations.
Это достигаетс тем, что на участке очистного забо , примыкающем к массиву полезного ископаемого, перпендикул рно очистному забою возвод т поддерживающие полосы, выкладываемые из блоков породного просло .This is achieved by installing support strips perpendicular to the mining face, which are laid out from the blocks of the rock interbed, perpendicularly to the mining face, adjacent to the mineral resource array.
полосы возвод т сплошными.the strips are erected solid.
Крайнюю со стороны массива полосу возводг.т с оставлением проходов.Extreme from the side of the massif the erection strip, leaving the aisles.
При отработке смежного столба полезное ископаемое транспортируют между крайней полосой отработанного столба и массивом отрабатываемого.When mining the adjacent pillar, the mineral is transported between the extreme band of the spent pillar and the massif worked out.
5five
На чертеже показана схема разработки .The drawing shows the design scheme.
Способ заключаетс в следующем.The method is as follows.
Пласт 1 полезного ископаемого отрабатывают длинным очистным забо0 ем 2 с применением механизированного комплекса. На участке, примыкающем к масси ву полезного ископаемого кровлю поддерживают полосами 3, возводимыми из блоков породного про5 сло перпендикул рно очистному забою . На участке, примыкающем к ранее отработанному столбу, производ т полное обрушение кровли. Полосы могут возводитьс сплошными. При воз0 ведении крайней со стороны массиваMineral reservoir 1 is worked by a long clearing hole 2 using a mechanized complex. In the area adjacent to the mass of the mineral fossil, the roof is supported by strips 3 erected from blocks of the rock pro5 layer perpendicular to the cleansing face. In the area adjacent to the previously spent column, the roof completely collapses. Stripes can be erected in solid. When resuming the extreme from the side of the array
