(54) СПОСОБ ОПЕРЕЖАЮЩЕГО КРЕПЛЕНИЯ ГОРНЫХ ВЫРАБОТОК С ПОМОЩЬЮ АНКЕРОВ(54) METHOD FOR EXTENDING FASTENING OF MINING BY ANCHORS

Изобретение относитс к способам опережающего креплени подъемных горных выработок с помощью анкеров.BACKGROUND OF THE INVENTION The invention relates to methods for advancing lifting mine workings using anchors.
. Известен способ упрочнени кровли горных выработок при помощи железобетонных анкеров, возводимых в нисход щих скважи,нах , причем установку анкеров осуществл ют до обнажени кровли из предварительно пройденной сверху выработки П).. There is a method of strengthening the roof of mine workings with the help of reinforced concrete anchors erected in downhole wells, and the installation of the anchors is carried out before the roof is exposed from the previously passed above production of P).
Недостатком известного способа вл етс значительна трудоемкость работ ввиду того, что дл осуществлени его необходимо пройти сверху спещ1альную выработку, которую к тому же также нужно закрепить.The disadvantage of this method is the considerable complexity of the work due to the fact that in order to accomplish it it is necessary to pass from above special production, which, in addition, also needs to be fixed.
Наиболее близким к изобретению по технической сущности и достигаемому результату вл етс способ опережающего креплени гор;ных выработок (ь помощью анкеров, включающий бурение наклонных опережающих скважин в направлении проведени выработки и установку в них анкеров 2.The closest to the invention to the technical essence and the achieved result is a method of advanced fastening of mountain workings (by means of anchors, including the drilling of inclined leading wells in the direction of development and installation of anchors in them 2.
Недостаток данного способа заключаетс в том, что наклонные анкеры не воспринима ют возникающие в массиве раст гивающиеThe disadvantage of this method lies in the fact that inclined anchors do not perceive the stretching
усили , вследствие чего снижаетс эффективность закреплени пород.force, thereby reducing the effectiveness of rock fixation.
Цель изобрете га -- повышение эффективности закреплени пород.The purpose of the invention is to increase the efficiency of rock consolidation.
Указанна цель достигаетс тем, что согласно способу опережающего креплени горных выработок при бурении наклонных опережающих скважин в направлении проведени выработки и установке в них анкеров после наклонной части бур т криволинейный учас10 ток, а потом : скважину бур т перпендикул рно к продольной оси выработки .This goal is achieved in that according to the method of advanced fastening of mine workings when drilling inclined lead wells in the direction of carrying out production and installing anchors in them after the inclined part, a curvilinear part is drilled, and then: the well is drilled perpendicular to the longitudinal axis of the mine.
На чертеже изображена схема опережающего креплени выработки с помощью анкеров предложенного способа.The drawing shows a diagram of the leading fastening production with the help of anchors of the proposed method.

Технологи способа опережающего креплени горных выработок с помощью анкеров заключаетс в следующем.The technology of advanced fastening of mines using anchors is as follows.
Перед отбойкой пород в забое на величину заходки а бур т скважины дл анкеров, Before breaking rocks in the bottomhole by the amount of entry and drilling of wells for anchors,
20 причем бурение первого участка каждой скважины длиной немного меньше, чем а/2, производ т под углом 30-70° к плоскости забо (участок 1), затем скважину искривл ют20 wherein the drilling of the first section of each well, which is slightly less than a / 2, is made at an angle of 30-70 ° to the bottom plane (section 1), then the well is bent
(участок; 2) и вывод т как можно точнее к перпендикул ру относительно продольной оси выработки (участок 3) с допускаемым отклонением концевого участка скважины от перпендикул ра в пределах ±20°. В пробурен 1Ые скважины могут быть установлены различные анкеры: полимерные, сталеполимерные, . железобетоиные. Длину анкера и соответствующую длину скважины выбирают, как обычно в зависимости от горногеологических условий проведени выработки, исход из требовани создани прочного упрочненного породного сло .(plot; 2) and output as accurately as possible to the perpendicular to the longitudinal axis of the mine (section 3) with a tolerable deviation of the end portion of the well from the perpendicular within ± 20 °. Various anchors can be installed in the 1X wells: polymer, steel-polymer,. reinforced concrete. The length of the anchor and the corresponding well length are chosen, as usual, depending on the geological and geological conditions of the development, based on the requirement to create a strong reinforced rock layer.
