Description

Изобретение относитс  к горным работам и можег найти применение в упрочении горных пород при проведении го зонтальных горных выработок дл  условий различного по периметру выработки давлени  торных пород, при котором аа ление в боках вьфаботки не превышает 2,0 т/м , а в кровле достигает 12 т/м и более. Известен способ тампонажа горных выработок путем дифференцированной подачи тампонирующего раствора в закрепленное пространство по периметру скважины . Известен также способ тампонажа го ризонтальных выработок В услови х неравномерного и преобладающего на свод выработки горного давлени  путем подачи тампонажного раствора в закрюплен- ное пространство по периметру выработки , включающему стенки и свод . При осуществлении этих способов тампонажный раствор подаетс  по всему периметру одного состава. Недостатком последнего  вл етс  неоправданный расход высокопрочного тампонажного раствора на упрочение боксеых пород стенок выработки, испытывающих горное давление по величине в несколько раз меньше, чем давление на свод выработки, что повышает стоимость тампонажных работ. Цель изобретени  - снижение стоимости тампонажных работ путем экономии высокомарочного строительного материала . Достигаетс  эта цель тем, что в известном способе тампонажа горизонтальных горных выработок в услови х нереюномерного и преобладающего на свод вьфаботки горного давлени  путем подачи тампонажного раствора в закрепное пространство по периметру выработки сначала в закрепное пространство стенок подают низкопрочный тампонажный раствор , а затем в закрепное пространство свода подают вьюокопрочный тампонажвый раствор.The invention relates to mining and can be used in the consolidation of rocks when conducting horizontal mine workings for conditions of pressure generation of rocks that differ in the perimeter, in which aloenie in the sides does not exceed 2.0 tons / m, and in the roof reaches 12 t / m and more. There is a method of cementing mining by differentiating the supply of plugging solution in the fixed space around the perimeter of the well. There is also a known method of plugging of horizontal workings. Under uneven conditions, the mine pressure prevailing on the arch is made by feeding the cement slurry into the closed space along the margin of the mine, which includes walls and roof. In carrying out these methods, the cement slurry is supplied around the entire perimeter of a single formulation. The disadvantage of the latter is the unjustified consumption of high-strength cement slurry for the consolidation of boxing rocks of the walls of the mine, experiencing rock pressure several times smaller than the pressure on the roof of the mine, which increases the cost of cement works. The purpose of the invention is to reduce the cost of grouting works by saving high-quality building material. This goal is achieved by the fact that in the well-known method of tamping of horizontal mine workings under conditions of irregular and predominant mining pressure, by feeding the cement slurry into the fixed space along the working perimeter, first, low-strength cement slurry is fed into the fixed space of the working area and then into the fixed space of the arch Serve a roll-resistant cement slurry.

Формула изобретенияClaim 15 Способ тампонажа горизонтальных горных выработок в условиях неравномерного и преобладающего на свод выработки горного давления путем подачи'тамния тампонажным раствором закрепного пространства боковых стенок выработки в зонах А осуществляется через сливные трубки, заложенные в крепи,!15 The method of tamping horizontal mine workings under conditions of uneven and prevailing mining pressure mining by filing with tampon grout the fixing space of the side walls of the mine in zones A is carried out through drain pipes laid in the lining! После заполнения закрепного простраш ства до уровня начала свода участка выра-J ботки тампонаж на этом участке прекращается и дается время на схватывание -2-3 дня. После схватывания низкопрочного раствора производится тампо понажного раствора в закрепленное пространство по периметру выработки, включающему стенки и свод, о т л и ч а тощи й с я тем, что, с целью снижения стоимости тампонажных работ путем экономии высокопрочного строительного материала, сначала в закрепное' пространство стенок подают низкопрочный тампонажный раствор, а затем в закрепное пространство свода подают высокопрочный тампонажный раствор.After filling in the restraining space to the level of the beginning of the arch of the section of the growth-J of the tamping, the tamping in this section is stopped and the time for setting is -2-3 days. After the low-strength mortar has set, the cement slurry is poured into the fixed space along the perimeter of the mine, including the walls and the arch, with the fact that, in order to reduce the cost of grouting by saving high-strength building material, first in the fixed the wall space serves low-strength cement slurry, and then in the fixed space of the arch serves high-strength cement slurry.
