(54) СПОСОБ РАЗРАБОТКИ МОЩНЫХ КРУТЫХ УГОЛЬНЫХ(54) METHOD FOR DEVELOPING POWERFUL, RAPPED COAL
ПЛАСТОВPLASTES
Изобретение относитс к горной промыш ленности и может быть использовано при разработке мощных крутых угольных пластов в сложных горно-геологических услови х . Известен способ разработки мощных крутых угольных пластов, включающий про ведение подготовительных выработок и от работку пласта поперечно-наклонными слоа . Известен также способ разработки . мощных крутых угольных пластов, включаюпшй проведение подготовительных выработок , отработку сло у кровли пласта длинными столбами по простиранию с воэведением гибкого разобщител на почве слон и закладкой выработанного пространства и выемку оставшейс толщи угл пласта сло ми с закладкой выработанного пространства под защитой разобщител Однако оба указанных способа характеризуютхр недостаточной эффективностью и безопасностью при разработке пластов в .сложных горно-геологических услови х. Целью изобретени вл етс обеспечение эффективной и безопасной ра аботки пластов в сложных горно-геологических услови х. Поставленна цель достигаетс тем, что оставшуюс толщу угл отрабатывают горизонтальными сло ми в нисход щем пор дке полосами по простиранию с выемкой полос поочередно и со смещением последних относительно друг друга; при отработке полосы на ее почву укладывают гибкое перекрытие, соедин емое при выемке полосы у лежачего бока пласта с поч:Вбй пласта и с гибким перекрытием смеж- ной заложенной полосы у разобщител и при выемке полосы у разобщител - с разобщителем и с гибким перекрытием- смех ной заложенной полосы у лежачего бока пласта; выемку полос производ т со см&щением последних относительно друг друса на половину высоты полосы. На чертеже представлена схема ведейин очистных работ.The invention relates to the mining industry and can be used in the development of powerful steep coal seams in complex mining and geological conditions. There is a method of developing powerful steep coal seams, which includes the development of preparatory workings and the treatment of the reservoir transversely inclined layer. There is also a method of development. powerful steep coal seams, including preparatory workings, mining the layer at the roof of the reservoir with long pillars along the strike with a flexible elephant on the ground and laying the mined-out space and dredging the remaining coal of the layers of the layer with laying the worked space under the protection of the separator insufficient efficiency and safety in the development of seams in difficult mining and geological conditions. The aim of the invention is to ensure efficient and safe working of formations in difficult mining and geological conditions. This goal is achieved by the fact that the remaining coal is worked by horizontal layers in a descending order of strips along the strike with the notch of the strips alternately and with the latter shifting relative to each other; when mining a strip, a flexible overlap is placed on its soil, which is connected when the strip is dredged on the recumbent side of the bed from the bottom: and the flexible overlap of the adjacent laid strip on the disconnector and on the strip of the disconnector — with a disconnector and flexible overlap — laughter Noah laid down strip at the recumbent side of the reservoir; The strips are notched with half of the height of the strip with respect to each other. The drawing shows a diagram Vedeyin treatment works.
