Description
(54) СПОСОБ УПРАВЛЕНИЯ КРОВЛЕЙ(54) ROOF CONTROL METHOD
1one
Изобретение относитс к горной промышленности и Может быть использовано при разработке пластов полезных ископаемых, преимущественно угл .The invention relates to the mining industry and may be used in the development of mineral formations, primarily coal.
Известен способ управлени труднообрушаемой кровлей, включающий бурение и взрывание скважин в породах труднообрущаемой кровли с предохранением от разрущени непосредственной кровли I.There is a known method of controlling a hard-to-cut roof, which includes drilling and blasting wells in the rocks of a hard-to-rubbing roof with protection from the destruction of the immediate roof I.
Известен также способ управлени кровлей при разработке пластов полезных ископаемых , включающий бурение скважин через непосредственную кровлю пласта в породы труднообрущаемой кровли и разоупрочнение пород в зоне раст гивающих напр жений труднообрущаемой кровли 2.There is also a known method of roof management in the development of mineral formations, which includes drilling wells through the direct roof of the formation into the rocks of a hard-to-reach roof and the strengthening of rocks in the zone of tensile stresses of the hard-to-wear roof 2.
Однако оба указанных способа недостаточно эффективны при слабой непосредственной кровле.However, both these methods are not effective enough with a weak immediate roof.
Цель изобретени - повышение эффективности управлени кровлей при слабой непосредственной кровле.The purpose of the invention is to increase the efficiency of roof management with a weak immediate roof.
Поставленна цель достигаетс те.м, что разупрочнение пород в зоне раст гивающих напр жений труднообрущаемой кровли производ т путем нагнетани через скважину в указанную зону растворов ПАВ и послеThe goal is achieved by the following principle: that the softening of rocks in the zone of tensile stresses of a hard-to-wear roof is carried out by injection through a well into the specified zone of surfactant solutions and after
разупрочнени пород через ту же скважину укрепл ют породы в зоне раст гивающих напр жений непосредственной кровли нагнетанием в эту зону скрепл ющего состава. Способ заключаетс в следующем. При разработке пласта полезного ископаемого через непосредственную кровлю в труд нообрущаемую кровлю бур т скважину. Насосной установкой по высоконапорному шлангу через герметизатор в зону раст гивающих напр жений труднообрущаемой кровли нагнетают раствор ПАВ. Пропитку массива производ т на величину эффективного радиуса увлажнени . После разупрочнени пород выпускают раствор ПАВ, перемещают герметизаторы и через ту же скважину укрепл ют породы, в зоне раст гивающих напр жений непосредственной кровли. Укрепление производ т путем нагнетани скрепл ющего состава.The softening of rocks through the same well strengthens the rocks in the zone of tensile stresses of the direct roof by forcing a bonding composition into this zone. The method is as follows. During the development of a mineral reservoir through a direct roof into a hard-to-work roof, a well is drilled. A pump installation along a high-pressure hose through a sealer in a zone of tensile stresses of a hard-to-wear roof is injected with a surfactant solution. The impregnation of the array is carried out by the effective radius of moisture. After the softening of the rocks, a surfactant solution is released, the sealers are moved, and the rocks are strengthened through the same well in the zone of tensile stresses of the immediate roof. Strengthening is done by injecting a bonding compound.
Данный способ позвол ет значительно по2Q высить эффективность управлени кровлей при слабой непосредственной кровле.This method makes it possible to significantly improve the efficiency of roof control with a weak direct roof.
