Description
Изобретение относитс к горной промышленности и может использоватьс при разработке моишых крутых угольных шастов, преимущественно в сложных горно-геологических услови х.The invention relates to the mining industry and can be used in the development of my coal steep coal strips, mainly in complex mining and geological conditions.
Известен способ разработки мощных крутых угольных пластов наклонными сло ми с применением твердеющей заюшдки выработанного пространства (1 .There is a method of developing thick steep coal seams with inclined layers using a hardening creep (1.
Однако данный способ характеризуетс сложными услови ми поддержани призабойного пространства, а также ограниченной областью применени на нарушенных пластах.However, this method is characterized by complex conditions for maintaining the wellbore space, as well as a limited scope for disturbed formations.
Известен также способ разработки мощных крутых угольных пластов, включающий отработку iuiacta в этажах сло ми с проведением транспортных и вентил ционных выработок в каждом слоем у лежачего и вис чего боков пласта и закладку выработанного пространства твердеющей смесью 2.There is also known a method for developing powerful steep coal seams, which includes testing iuiacta in floors with carrying out transport and ventilation workings in each layer near the lying and hanging sides of the reservoir and laying the worked-out space with a hardening mixture 2.
Однако этот способ недостаточно эффективен при разработке пластов в сложных горно-геологических услови х, например при нарушенности пластов по падению.However, this method is not sufficiently effective in the development of reservoirs in complex mining and geological conditions, for example, when the formation is disturbed by falling.
Цель изобретени - повышение эффективности обработки пластов в сложных горно-геолопетеских услови х.The purpose of the invention is to increase the efficiency of formation treatment in difficult mining and geological conditions.
Это достигаетс тем, что обработку пласта ведут вертикальными сло ми по простиранию в нисход щем пор дке.This is achieved by treating the formation with vertical layers along the strike in descending order.
На чертеже приведена схема ведени очистных работ.The drawing is a schematic diagram of the maintenance work.
Вскрытие выемочного пол осуществл ют гранспортным I и вентил ционным 2 квершлагами , которые соединшот наклонной выработкой 3, проводимой по потае пласта. По кровле пласта в створе с выработкой 3 участками по мере отработки слоев провод т наклонную выработку 4. Пласт отрабатьшают вертикальными сло ми с проведением транспортного 5 и вентил ционного 6 оюевых иттреков на длину выемочного пол . На границе выемочного пол штреки 5 и 6 соедин ют вертикальной очистной выработкой 7, которую подвигают по простиранию. Закладку при отработке слоев осуществл ют твердкощей смесью, а слои отрабатывают в Нисход щем пор дке.Opening of the excavation floor is carried out with a special I and a ventilation 2 trench, which are connected with an inclined excavation 3, carried out through the sweat of the formation. Along the top of the reservoir in the alignment with the development of 3 sections, as the layers are worked out, the inclined development is performed. At the border of the excavation floor, drifts 5 and 6 are connected by a vertical clearing excavation 7, which is moved along the strike. The laying during the working of the layers is carried out with a solid mixture, and the layers are worked out in a descending order.
