Description
(54) СПОСОБ ОБРУШЕНИЯ ОТКОСА(54) METHOD OF ROLLING OUT
Изобретение, относитс к горному делу, а более конкретно - к обрушению откосов уступов карьеров, сложенных рыхлыми породами.The invention relates to mining, and more specifically to the collapse of the slopes of the ledges of quarries, composed of loose rocks.
Известен способ обрушени откосов уступов, который осуществл етс обрушивающими машинами There is a known method of breaking down ledges, which is carried out by breaking machines.
Однако дл его применени нужно Зс1далживать рабочую силу и комплексы оборудовани .However, for its application, it is necessary to extend labor and equipment complexes.
Известен также способ обрушени откоса, по которому проход т канаву вблизи его верхней бровки, заполн ют ее водой и выдерживают до водонасыщени и потери устойчивости массива пород , слагакщих откос 21.There is also known a method of breaking down a slope, along which a ditch passes near its upper edge, is filled with water and maintained until it is saturated with water and the buckling of an array of rocks that slope 21.
Недостатком этого способа вл етс то, что из-за одинаковой проницаемости стенок и дна канавы насыщение массива водой происходит в основном в вертикальном направлении, а не по направлению линии скольжени ,что при повышенном расходе воды ведет к неравномерному обрушению массива.The disadvantage of this method is that, due to the same permeability of the walls and the bottom of the ditch, the saturation of the array with water occurs mainly in the vertical direction and not along the direction of the slip line, which, with an increased flow of water, leads to uneven collapse of the array.
Целью изобретени вл етс улучшение качества обрушени пород путем направленного воздействи воды на откос .The aim of the invention is to improve the quality of rock caving by the directional influence of water on a slope.
Дл достижени поставленной цели канаву в поперечном сечении устраивают треугольной формы, при этом стенку, расположенную ближе к откосу, выполн ют с крутизной, равной углу с естественного откоса слагающих ее пород , а другую - под углом, меньшим естественного откоса, и нанос т на нее водонепроницаемый слой.To achieve the goal, a ditch in cross section is arranged in a triangular shape, with the wall closer to the slope being made with a slope equal to the angle from the natural slope of the rocks forming it, and the other at an angle less than the natural slope, and applied to it waterproof layer.
На чертеже показана схема осущест10 влени способа.The drawing shows a scheme for implementing the method.
Канаву 1, имею(цую в поперечном сечении треугольную форму, провод т вблизи бровки откоса 2 по границе предполагаемой призмы обрушени от15 коса 3-5. На пологую стенку нанос т водонепроницаемый слой 6, например, из глины. Крутой стенке придают уклон , равный углу естественного откоса породы. По верху канавы 1 со сторо20 ны ее крутой стенки может быть устроен водоупорный барьер 8 дл повышени уровн воды в канаве.I have a ditch 1 (I have a triangular cross-section in cross section, drawn near the side of the slope 2 along the border of the supposed prism of waving from 15 to spit 3-5. A waterproof layer 6, such as clay, is applied to the gently sloping wall. A steep wall is given a slope equal to the angle natural repose of the rock. On the top of the ditch 1 on the side of its steep wall, a waterproof barrier 8 can be arranged to raise the water level in the ditch.
При заполнении канавы вода проникает через стенку 7.в массив пород, When filling the ditch, water penetrates through the wall 7.in the rock mass,
25 насыщс1Я его. преимущественно вдоль : поверхности скольжени 3-4. Эпюра распространени воды в массиве представлена лини ми 9. При достижении критического вoj:toнacыщeни призма 30 обрушени перемещаетс вниз.25 saturate him. mainly along: sliding surface 3-4. The plot of water distribution in the massif is represented by lines 9. When a critical wave is reached: to saturate, the collapse prism 30 moves downwards.
При использовании предложенного способа снижаетс расход воды и обеспечиваетс более плавка поверхность откоса после обрушени порол. Применение способа экономично и в сочетании с напорным размывом пород. By using the proposed method, the water consumption is reduced and the surface of the slope is melted after the foil has collapsed. The application of the method is economical and in combination with pressure erosion of rocks.
