Description
II
Изобретение относитс к горной промышленности и может быть использовано при разработке мощных крутых угольных пластов.The invention relates to the mining industry and can be used in the development of powerful steep coal seams.
Известен способ разработки мощных крутых угольных пластов, включающий отработку пласта подэтажами с закладкой выработанного пространства и разделением подэтажей гибким перекрытием 1.There is a method of developing powerful steep coal seams, which includes mining the reservoir with sub-floors with laying the worked-out space and separating the sub-floors with flexible overlap 1.
Известен также способ разработки мощных крутых угольных пластов, включающий отработку пласта подэтажами в нисход щ;ем пор дке с закладкой выработанного пространства и возведением на почве каждого подэтажа изол ционного сло , проведение в пределах каждого подэтажа подэтажного щтрека и закладочного штрека, расположенного под изол ционным слоем, и механизированную отбойку угл в подэтаже 2.There is also a known method for developing powerful steep coal seams, which includes mining the reservoir by sub-floors in descending order, with laying the mined-in space and building an insulating layer on the ground of each substage, conducting within the substage of the subsurface gateway and a filling tunnel located under the insulating layer , and mechanized coal blasting in sub-floor 2.
Однако оба указанных способа характеризуютс недостаточной безопасностью и эффективностью ведени горных работ.However, both of these methods are characterized by inadequate safety and efficiency of mining operations.
Целью изобретени вл етс повышение безопасности и эффективности ведени горных работ.The aim of the invention is to increase the safety and efficiency of mining operations.
Поставленна цель достигаетс тем, что ло мере закладки выработанного пространства каждого подэтажа закладочный щтрей возвод т в закладочном массиве, а отбойку угл в подэтаже осуществл ют с оставлением у кровли пласта временной пачки угл , которую вынимают непосредственно перед закладкой выработанного пространства.This goal is achieved by the fact that, to the extent of laying out of the developed space of each substage, the stowing shields are erected in the stowing massif, and the coal is crushed in the substage, leaving a temporary wad of coal at the roof of the formation, which is removed immediately before laying the worked-out space.
На фиг. 1 представлена схема ведени очистных работ в подэтаже; на фиг 2 - схема выемки забо .FIG. 1 is a diagram of the maintenance work in the sub-floor; Fig 2 - diagram of the excavation of the slab.
Способ заключаетс в следующем. Мощный крутой угольный пласт отрабатывают подэтажами 1 в нисход щем пор дке с закладкой выработанного пространства. Выемку угл производ т под защитой изол ционного сло 2, который возвод т при отработке каждого подэтажа на его почве. Выемку угл ведут из подэтажного щтрека 3 механизированным комбайном 4 с оставлением временной пачки угл 5, которую вынимают непосредственно перед закладкой выработанного пространства. Закладочный штрек 6 возвод т в закладочном массиве и Из него производ т подачу закладочного материала в выработанное пространство по закладочThe method is as follows. The powerful, steep coal seam is worked out by sublevels 1 in a downward order with the laying of the goaf. The coal is removed under the protection of the insulating layer 2, which is erected when each substage is developed on its soil. The excavation of coal is carried out from the subsurface level 3 with a mechanized combine 4, leaving a temporary bundle of coal 5, which is removed immediately before laying the developed space. The filling stitch 6 is erected in the filling mass and from it the filling material is fed into the worked space through the filling space.
