Изобретение относитс к горной промышленности и может быть использовано при разработке угольных пластов с труднообрушаемЕлми кровл ми.The invention relates to the mining industry and can be used in the development of coal seams with hard-to-break EMI roofs.
Известен способ управлени труднообрушаемой кровлей, включаю дий в себ бурение скважик в труднсобрушаемую .кровлю и взрывание этих скважин 1.There is a known method of controlling a roof that is hard to break, including drilling a hole into a roof that is difficult to break and blasting these wells 1.
Известен также способ управлени труднообрушаемой кровлей, включающий в себ бурение скважин из монтажной камеры по направлению отработки выемочного столба и скважин из выработок, оконтуриваюцих выемочный столб, вдоль линии очистного забо в труднообрушаемую кров.пю с последующим взрыванием указанных скважин 2. .There is also known a method of controlling a hard-to-collapse roof, which includes drilling wells from the installation chamber in the direction of mining of the excavation column and wells from the workings, outlined by the excavation column, along the line of the cleansing slab with subsequent blasting of these wells 2.
Однако оба указанных способа недостаточно эффективны в определенных горно-геологических услови х.However, both of these methods are not effective enough in certain geological conditions.
Цель изобретени - повышение эффективности управлени труднообрушаемой кровлей.The purpose of the invention is to increase the efficiency of management of a hard-to-damage roof.
Поставленна цель достигаетс тем, что скважины из монтажной камеры бур т длиной более естественного шага осадки труднообрушаемой кровли в зону раст гивающих напр жеНИИ ее плиты. При этом рассто ние между скважинами, которые бур т из мок .-а-жной камеры, принимают равным 1/3 естестаекного шага осадки трудноo6piiLiaeMOK кров.пи.This goal is achieved by the fact that the wells from the installation chamber are drilled with a length of a more natural pitch of precipitation of a roof that is difficult to break into the zone of tensile stress of its plate. At the same time, the distance between the wells that are drilled from the wet-a-chamber, is equal to 1/3 of the natural-step step of precipitation of a blood space.
Способ заключаетс в следующем. Цп oGpiiueHiiH труднообрушаемой кровпи и предотвращени завалов очистных забоев из монтажной камеры вдоль The method is as follows. CPU oGpiiueHiiH hard-to-crush and prevent blockages of longwalls from the assembly chamber along

Из The direction of working out in the area of the GIB aicLuHx stresses of the slab of a hard-to-break roof is a borehole with a length of more natural spacing of the hard-to-break roof. Of

Рассто ние между скважинами , которые бур т из монтажной ка0 меры, могут принимать равным 1/3 естественного шага осадки труднообрушаемой кровли. Взрывание указанных скважин обеспечивает разупрочнение пород кровли по нескольким 5 preparatory workings; delineating the excavation column, additional wells are drilled along the clearing site. The distance between the wells that are drilled from the installation chamber can be equal to 1/3 of the natural pitch of the precipitation of a hard-to-collapse roof. Blasting these wells provides softening of the roof rocks for several
