Description
скат 3 ио породе, который соедин ют ортами 4 с конвейерными штреками 5, пройдонными по ппасту у почвы последнего, Подэгажные штреки 6 провод т через 6-8 м и у грани-, цы блока соедин ют ходовой печью. Вентиа цйю при проведении подэтажных штреков осуществл ют через скважины 7 за счет общешахтной депрессии. Очистные работы начинают после проведени не менее трех подэтажных штреков и-одного конвейерного штре ка. Забой располагают под углом 70-75 к линии простирани пласта. У почвы пласта в каждом из отрабатываемых подэтажей вынимают опережающую щель 8 путем взрывани шпуров, пробуренных в почву подэтажных штреков с наклоном в сторону выработанного пространства. Оставшуюс толщу угл отрабатывают забоем зигзагообразной формы 9 путем взрывани шпуров, пробуренных в каждом подэтаже из подэтажных штре ков с наклоном в сторону выработанного пространства во встречном направпёнии. При этом создают промежуточные опоры 1О дп гибкого перекрыти 11. Транспортирование угл осуществп ют вдоль длинного забо в дополнительном призабойном пространстве, ограниченном по простиранию с одной стороны гибким перекрытием и с другой - забоем опережающей щели.slope 3 of the rock, which is connected by orths 4 with conveyor drifts 5, passed along the soil of the latter, Podagazhny drifts 6 are led through 6-8 m and near the edge of the block are connected by a running furnace. When ventilating sublevel drifts, the vent is performed through wells 7 due to a general depression. Cleaning work begins after at least three sublevel drifts and a single conveyor drift. The face is positioned at an angle of 70-75 to the strike line of the formation. At the soil of the reservoir in each of the sublevels being worked out, the leading gap 8 is removed by blasting holes drilled into the soil of sublevel drifts with a slope towards the developed space. The remaining coal is worked by zigzag-shaped bottom 9 by blasting holes drilled in each sub-floor of sublevel drifts with an inclination towards the developed space in the opposite direction. At the same time, intermediate supports 1O dp of flexible overlap 11 are created. Transportation of coal is carried out along a long bottom in an additional bottomhole space, which is limited along the strike by one side with a flexible overlay and on the other by a bottom of the leading gap.
