Description

Изобретение относитс  к горной промышленности и может быть использовано при разработке мощных пологих угол ных пластов. Известен способ разработки мощных ПФ1ОГ1КХ. угольных пластов наклонными сло ми, двум  очистными забо ми, ocHai шенными спаренными механизированными комплексами, с опережением нижнего забо  верхним . Однако данный способ имеет ограниченную область применени  по мощности пласта. Известен также способ выемки мощн пологих угольньос пластов наклонными сло ми трем  очистными забо ми, оснащенными механизированными комплексами , с опережением нижнего и среднего забоев верхним 1а управлением кровлей полным обрушением L JДанный способ недостаточно эффективен в определенных горно-геологических услови х и ха)актеризуетс  большим объемом подготовительных выработок.. Целью изобретени   вл етс  повышение эффективности выемки и уменьшение объема подготовительных работ. Это достигаетс  тем, что выемку угл  осуществл ют сразу на всю мощность пласта с опережением среднего забо , имеющего наклон в сторону его груди, нижним забоем, причем направление движени  комплекса среднего забо  принимают перпендикул рным направлению движени  комплексов верхнего и нижнего забоев, а обрушение кровли производ т на общее дл  трех забоев перекрытие. На чертеже представлена схема выемки , реализующа  предлагаемый способ. Мощный пологий пласт отрабатывают сло ми 1, 2 и 3 сразу на всю мощность очистными забо ми 4, 5 и 6, оснащенными механизированными комплексами 7, 8 и 9. рхний забой опережает нижний, а нижний забой опережает средний.. Среднему забою придают наклон в сторону его груди. Направление движени  комплекса среднего забо  принимают перпенднThe invention relates to the mining industry and can be used in the development of thick flat angular seams. There is a method of developing powerful PF1OG1KH. coal seams with inclined layers, two clearing faces, ocHai shennymi paired mechanized complexes, ahead of the bottom one of the top. However, this method has a limited scope in terms of reservoir thickness. There is also known a method of excavation by powerfully gentle coal seams with inclined layers of three cleansing faces equipped with mechanized complexes, ahead of the lower and middle faces of the upper roof management 1a with full collapse L J This method is not effective enough in certain geological conditions and ha) is ateraged with a large volume developmental workings. The aim of the invention is to increase the efficiency of excavation and reduce the amount of preparatory work. This is achieved by removing the coal immediately to the entire thickness of the reservoir, ahead of the middle bottom, which has an inclination in the direction of his chest, the bottom face, and the direction of movement of the middle bottom complex is taken perpendicular to the direction of movement of the top and bottom faces. t on the total for three faces overlap. The drawing shows a recess diagram that implements the proposed method. A powerful flat layer is worked out with layers 1, 2 and 3 at once for all of its power with cleaning faces 4, 5 and 6, equipped with mechanized complexes 7, 8 and 9. The bottom face is ahead of the bottom one, and the bottom bottom is ahead of the middle one. side of his chest. The direction of movement of the middle-hole complex is perpendicular.
