Изобретение относитс к горной промышленности и предназначено дл разработки мощных пологих пластов полезных ископаемых.The invention relates to the mining industry and is intended to develop thick, flat seams of minerals.
Известен способ разработки мощных пологих пластов полезных ископаемых 1.There is a method of developing powerful flat seams of minerals 1.
Однако этот способ характеризуетс недостаточной эффективностью.However, this method is characterized by insufficient efficiency.
Известен разработки мощных пологих пластов, включающий разделение пласта на слои, проведение подготовительных выработок, выемку полезного ископаемого лавами с выпуском его. в выработку нижнего сло и закладку выработанного пространства 2.Known to the development of powerful flat seams, including the separation of the reservoir into layers, holding preparatory workings, excavation of mineral fossils with the release of it. into the development of the lower layer and the laying of the goaf 2.
Известный способ также недостаточно эффективен,The known method is also not effective enough
Цель изобретени - повышение эффективности разработки мощных пологих пластов.The purpose of the invention is to increase the efficiency of the development of powerful flat seams.
Поставленна цель достигаетс тем, что выемку полезного ископаемого производ т раздельно сло ми и камерами, причем сначала вынимают верхний слой у кровли пласта, а затем два сло , расположенные диагонально по мощности пласта под углом друг к другу, после чего отбивают и выпускают полезное ископаемое из образованной камеры с одновременной отработкой нижнего сло .The goal is achieved by the fact that the mineral excavation is carried out separately by layers and chambers, first removing the upper layer at the top of the reservoir, and then two layers located diagonally along the thickness of the reservoir at an angle to each other, and then kicking and releasing the mineral from formed by the camera while simultaneously working out the lower layer.
Длина лавы не превышает длины предельного устойчивого пролета основной кровли.The length of the lava does not exceed the length of the maximum stable span of the main roof.
Закладку, возвод т только в сло х.Bookmark, raised only in layers.
Закладку возвод т как в сло х, так и в камерах.The bookmark is erected both in the layers and in the chambers.
На фиг. 1 показан способ выемки весьма мощного пласта; на фиг. 2 способ выемки пласта мощностью до 20 м.FIG. 1 shows a method for excavating a very thick formation; in fig. 2 method of excavation reservoir up to 20 m.
