Изобретение относитс к горной промьшшенности и предназначено дл механизирЬв нной разработки мощных крутых пластов угл .The invention relates to the mining industry and is intended for the mechanized development of powerful steep coal seams.
Целью изобретени вл етс снижение трудоемкости работ.The aim of the invention is to reduce the labor intensity of the work.
Способ осуществл етс следующим образом.,The method is carried out as follows.
При механизированной разработке мощных крутых пластов угл выемочные поле раздел ют скатами, на участки , выемку угл производ т длинными горизонтальными сло ми по простиранию в нисход щем пор дке с переходо выемочного комбайна на нижележащийIn the mechanized development of powerful steep seams, coal excavation fields are divided by slopes, into sections, the coal is excavated by long horizontal layers along the strike in descending order from the transition of the excavating combine to the underlying

слой. Управление кровлей осуществл ют литой твердеющей закладкой. При I отработке слоев средний скат перекрывают щитом и выемку угл ведут со 5 щита от указанного ската поочередноlayer. The roof is controlled by a cast hardening tab. When I work out the layers, the middle slope is covered with a shield and coal is dredged from the shield 5 from the specified slope alternately.
к флангам выемочного пол со сме- щением слоев по простиранию пласта на половину высоты сло , хфичем переход выемочного комбайна на нижеле- 10 жащий слой осуществл ют посредством соединени щитом почвы отработанного сло в одной половине выемочного пол с почвой очередного в друг ой поло- I вине выемочного пол с отработкой 15 угл под щитом.to the flanks of the excavation floor with the layers displaced along the strike of the formation half the height of the layer, the transition of the excavation combine to the lower layer is carried out by connecting the waste layer in one half of the excavation floor with the soil to the next half of the excavation floor with a shield excavation floor with a working out of 15 coal under the shield.
