(54) СПОСОБ ОХРАНЫ ПОДГОТОВИТЕЛЬНЫХ ВЫРАБОТОК(54) METHOD OF PROTECTION OF PREPARATORY WORKS
1one
Изобретение относитс к горнодобывающей промышленности и предназначено дл охраны пластовых подготовительных выработок в услови х крутого и крутонаклонного залегани пород.The invention relates to the mining industry and is intended to protect reservoir development workings under conditions of steep and steeply inclined rock formations.
Известен способ охраны подготовительных выработок 1.There is a method of protection of development workings 1.
Известен также способ охраны подготовительных выработок, включающий установку в выработанном пространстве вдоль выработки искусственных организаций 2.There is also known a method for the protection of preparatory workings, including the installation in the developed space along the production of artificial organizations 2.
Недостатком указанного способа охраны выработок на пластах крутого и крутонаклонного падени вл етс невысока несуща способность искусственных ограждений .The disadvantage of this method of protecting workings on steep and steeply inclined seams is the low bearing capacity of artificial fences.
Цель изобретени - улучшение условий поддержани подготовительных выработок при крутом и крутонаклонном залегании пластов с бесцеликовой их охраной.The purpose of the invention is to improve the conditions for maintaining preparatory workings with steep and steeply inclined layers with their targetless protection.
Поставленна цель достигаетс тем, что дополнительно в почве и кровле вынутого пласта устанавливают р дами анкеры, причем нижний р д располагают вдоль подготовительной выработки, а верхний - выще искусственного ограждени , и оба р даThe goal is achieved by additionally installing anchors in the soil and roof of the excavated reservoir, with the lower row being placed along the preparatory development, and the upper row being located above the artificial fence, and both
анкеров соедин ют между собой ст жками, при этом анкеры первого р да в кровле соедин ют с анкерами второго р да в почве пласта, а анкеры первого р да в почве соедин ют с анкерами второго р да в кровле пласта.The anchors are interconnected with straps, the first row anchors in the roof being connected to the second row anchors in the formation soil, and the first row anchors in the soil are connected to the second row anchors in the top of the reservoir.
На чертеже показан разрез вкрест простирани пород с выработкой, охран емой бесцеликовым способо.м.The drawing shows a section across the strike of rocks with a development protected by purposeless methods.
Способ охраны подготовительных выработок при бесцеликовой технологии отработки крутых и крутонаклонных пластов реализуетс следующим образом.The method of protection of preparatory workings with the aimless technology of mining steep and steeply inclined seams is implemented as follows.
После выемки угл в лаве над выработкой 1 в очистном пространстве бур т параллельно выработке р ды скважин в кровле 2 и почве 3 отработанного пласта. В эти скважины устанавливают анкеры первого р да 4 и 5, расположенные ближе к выработке 1, а анкеры 6 и 7, расположенные дальше от выработки. Длина анкеров 20 и шаг их установки вдоль выработки, а также рассто ние между первым и вторым р дом определ ютс , исход из горно-геологических условий залегани пласта, характера возможного сползани пород, наличи в почве и кровле пласта слабых глиHHCjbix прослоев, физико-механических свойств пород и других факторов. Возвод т искусственное ограждение 8 ввиду кустокостров, костров или органной крепи. Затем соедин ют анкеры первого р да 4 в кровле с анкерами второго р да в почве 7 ст жкой 9, а анкеры первого р да в почве 5 с анкерами второго р да в кровле 6 ст жкой 10. Производ т нат жение ст жек 9 и 10 с помощью нат жных устройств, что ;о;}вол ет включить ст жки сразу в работу. Предложенный способ охраны подгото|п;те ., выработок позвол ет улучшить услови их поддержани .After excavation, the coal in the lava above the excavation 1 in the cleaning space is drilled in parallel with the development of a series of wells in the roof 2 and the soil 3 of the spent formation. In these wells, anchors of the first row 4 and 5 are installed, located closer to development 1, and anchors 6 and 7, located farther from the development. The length of the anchors 20 and the step of their installation along the working, as well as the distance between the first and second row are determined on the basis of the geological conditions of the reservoir, the nature of the possible creep, the presence of weak layers in the soil and the roof of the reservoir, physical-mechanical rock properties and other factors. Build an artificial fence 8 in view of the bush, fires or organ lining. Then connect the anchors of the first row 4 in the roof with the anchors of the second row in the soil 7 of the strand 9, and the anchors of the first row in the soil 5 with the anchors of the second row in the roof of the 6 tie-rod 10. Pull the tension of the straps 9 and 10, with the help of tensioning devices, that; o;)} it is necessary to put the straps into operation immediately. The proposed method of guarding the preparation of the workings allows to improve the conditions for maintaining them.
