Description
Изобретение относитс к области креплени и поддержани горных выработок в пучащих породах, проводимых вприсечку к выработанному пространству.The invention relates to the field of fastening and maintaining mine workings in pulling rocks, which are carried in the extension to the developed space.
Известны способы поддержани горных выработок с пучащими породами почвы, заключающиес в укреплении последних анкерной крепью I.Methods are known for maintaining mine workings with thickening soil rocks, which consist in reinforcing the latter with anchoring I.
Недостатком этого способа вл етс больща трудое.мкость операции, кроме того, смещение пород не исключаетс , а лищь замедл етс в 1,5-2,0 раза. В дальнейшем не удаетс избежать большого объема работ, св занных с поддиром выдавленных в сечение выработки пород почвы.The disadvantage of this method is the greater difficulty of the operation, in addition, the displacement of rocks is not excluded, and the deceleration is slowed down 1.5-2.0 times. In the future, it is not possible to avoid the large amount of work associated with the subdire squeezed into the cross section of the development of soil rocks.
Наиболее близким к предлагаемому вл етс способ поддержани присечных выработок с пучащей почвой, включающий установку лежки на ровную почву выработки, стоек и верхн ка 2.Closest to the present invention, there is a method of maintaining the subsectional workings with tipping soil, including the installation of maturation on level soil, racks and top 2.
Недостатком данного способа вл етс то, что он не позвол ет сохранить выработку в рабочем состо нии на весь период ее службы. Происходит это из-за большой реакции пород почвы с разрушением лежней и выдавливанием пород в сечение выработки .The disadvantage of this method is that it does not allow to keep production in working condition for the entire period of its service. This is due to the large reaction of the soil rocks with the destruction of the bosses and the extrusion of rocks into the cross section of the mine.
Цель изобретени - увеличение срока службы выработки путем исключени выдав ливани пород в сечение выработки.The purpose of the invention is to increase the service life of the mine by eliminating the pouring of rocks into the cross section of the mine.
Поставленна цель достигаетс тем, что почву выработки устраивают наклонной в сторону массива дл установки лежн , имеющего обратный уклон, причем лежень по поверхности контакта с почвой выработки предварительно обрабатывают антифрик10 ционным средством.This goal is achieved by arranging the working soil inclined towards the array to install a bed that has a reverse slope, and the soil on the contact surface with the working soil is pretreated with antifriction means.
На фиг. 1 изображено крепеление горной выработки, общий вид.FIG. 1 shows the attachment of the mine workings, a general view.
Способ осуществл етс следующим образом .The method is carried out as follows.
Почву выработки выполн ют наклонной The soil is made sloping
15 в сторону массива и на нее укладывают леж ни 1 с обратным уклоном, причем лежень на поверхности 2 контакта с почвой предва рительно обрабатывают антифрикционным 20 средством, затем производ т установку стоек 3 и верхн ка 4.15 in the direction of the array and on it are laid 1 with a reverse bias, and the ground on the surface 2 of contact with the soil is pretreated with antifriction 20 means, then the racks 3 and the top 4 are installed.
исследовани ми установлено, что выдав ливание пород почвы в отработанное пространство из-под лежн будет происходитьstudies have established that the squeezing of soil rocks into the waste space from under the bed will occur
потому, что напр жение на контакте обрушенные породы - почва меньше, чем напр жение На контакте массив угольного пластапочва .because the voltage at the contact of the collapsed rocks - the soil is less than the voltage On the contact is an array of coal plastapoch.
Обработка лежн по поверхности контакта с породой почвы способствует большому смешению и выдавливанию пород по поверхности лежн в сторону выработанного пространства.The processing of the bed along the surface of contact with the rock of the soil contributes to a great mixing and extrusion of the rocks along the surface of the bed towards the developed space.
Использование предлагаемого способа поддержани присечных выработок позвол ет получить значительный экономический эффект.The use of the proposed method for maintaining the pit openings allows to obtain a significant economic effect.
Экономи На 1 м выработки составл ет 26,8 руб.Economy On 1 m of production is 26.8 rubles.
