Изобретение относитс  к горному делу и может быть использовано при разработке пологих и наклонных угольных пластов.The invention relates to mining and can be used in the development of flat and sloping coal seams.

Известны способы разработки пологих и наклонных угольных пластов с выемкой угл  из участковых печей У-образным забоем агрегатом с поворотной отбойной головкой полосами по падению в камере - пр мым ходом , а в междукамерном целике - обратным.Methods are known for developing flat and inclined coal seams with coal dredging from district furnaces with a U-shaped bottom by an aggregate with a rotary baffle head strips in the chamber in a straight line, and in the rear-chamber rear panel.

The support lugs are extended by hydraulic jacks 13 and secure the rear sight from the side of the worked-out space. From the camera side, the rear sight holds the unit. To move the support mate there is a hydraulic jack J4, which is located between the disks. Tansnuyu part of the strip 15 in bremsbergovoy
