Description
(54) СПОСОБ РАЗРАБОТКИ УГОЛЬНБ1Х ПЛАСТОВ(54) METHOD FOR DEVELOPING CARBON PLANTS
Изобретение относитс к горной промышленности и может быть использовано дл безлюдной разработки угольных пл-астов. Известен способ разработки угольных пластов, включаюш,ий проведение транспортного и вентил ционного штреков и отработку выемочного столба полосами выемочным агрегатом с оставлением целиков угл между полосами 1. Однако данный способ характеризуетс значительными потер ми угл . Известен также способ разработки угольных пластов, включающий проведение бортовых и промежуточного штреков и отработку пластаспаренными очистными забо ми с попеременной выемкой угл в одном из очистных забоев и управлением кровлей в выработанно-м пространстве другого с помошью челнокового выемочного агрегата , перемеш,аемого вдоль забоев 2. Однако данный способ не обеспечивает проветривани очистных забоев и при его применении происходит полное обрушение кровли, что недопустимо при разработке пластов под охран емыми объектами и в случае необходимости предотвращени сдвижени земной поверхности. Цель изобретени - обеспечение проветривани очистных забоев и предотвращение обрушени кровли. Поставленна цель достигаетс тем, что управление кровлей производ т путе.м подачи твердеющей смеси в выработанное пространство вслед за проходом агрегата полосами шириной, равной ширине захвата выемочного агрегата, при этом полосу формируют на рассто нии от линии забо , равном половине ширины захвата указанного агрегата , а твердеющую смесь подают с промежуточного штрека. На чертеже представлена схема ведени горных работ. При подготовке пласта угл провод т бортовый 1 и промежуточный 2 штреки. Отрабоку пласта производ т спаренными очистными забо ми 3 и 4 с помощью челнокового выемочного агрегата 5, передвигаемого вдоль забоев. Во врем выемки угл в очистном забое 4 в очистном забое 3 производ т управление кровлей. Управление осуществл ют путем подачи твердеюThe invention relates to the mining industry and can be used for the unmanned development of coal flat-fired. A known method for developing coal seams, including carrying out transport and ventilation drifts and mining the extraction column with strips by the excavation unit, leaving the coal between the lanes 1, however, this method is characterized by significant coal losses. There is also known a method for developing coal seams, including conducting side and intermediate drifts and working with plastafted clearing holes with alternate coal mining in one of the mining faces and roof management in the developed space of the other using a shuttle excavation unit, mixed along the mining faces 2. However, this method does not provide airing of the mining faces, and when it is used, the roof collapses completely, which is unacceptable when developing seams under protected objects and in when necessary to prevent the movement of the earth's surface. The purpose of the invention is to provide airing of the mining faces and prevent roof collapse. The goal is achieved by the fact that the roof is controlled by feeding the hardening mixture into the developed space, following the passage of the aggregate by strips of width equal to the working width of the excavating machine, while the strip is formed at a distance of half the working width of the specified aggregate, and the hardening mixture is fed from the intermediate drift. The drawing is a mine management scheme. When preparing the seam, coal is spent onboard 1 and intermediate 2 drifts. The seam side was produced by paired clearing faces 3 and 4 with the help of a shuttle shuttle excavation unit 5 moved along the faces. During coal removal in the downhole 4 in the downhole 3, the roof is controlled. Control is carried out by feeding harden.
