Изобретение относитс к горной пр мьп.иленности и может быть использовано при открытой разработке месторождений полезных ископаемых дл укреплени поверхности скальных откосов карьеров.The invention relates to mountain landings and can be used in the open-pit mining of mineral deposits to strengthen the surface of the rock slopes of quarries.
Известен способ укреплени поверхности скальных откосов карьеров, вклчающий установку свай за линией будущего откоса l.There is a known method of strengthening the surface of rocky slopes of quarries, which includes the installation of piles behind the future slope l.
Известен также способ укреп.г1ени поверхности скальных откосов карьеров , включающий нагнетание цементного раствора через вертикальные скважины 2.There is also known a method of strengthening the surface of the rock slopes of quarries, including the injection of cement through vertical wells 2.
Однако эти способы недостаточно эффективны и не предотвращают выветривание поверхности откоса.However, these methods are not effective enough and do not prevent the weathering of the surface of the slope.
Цель изобретени - повьрение эффективности укреплени и предотвращени выветривани поверхности откоса ,The purpose of the invention is to improve the effectiveness of strengthening and preventing weathering of the surface of the slope,
Эта цель достигаетс тем, что до подхода горных работ к предельному контуру карьера параллельно .поверхности будущего откоса взрывом наклонных скважин создают зоны дроблени и раскрыти трещин, которые затем цементируют через армированные вертикальные скважины, верхнюю свободную часть которых используют при оформлении уступа.This goal is achieved by the fact that, prior to mining, the pit contour is parallel to the surface contour of the future slope by the explosion of inclined wells and creates fracture zones and fractures, which are then cemented through reinforced vertical wells, the upper free part of which is used in the design of the ledge.
На чертеже представлена схема укреплени поверхности скальных откосов карьеров.The drawing shows a diagram of the strengthening of the surface of the rock slopes of quarries.
Способ заключаетс в следующем. При подходе горных работ к границе карьера бур т наклонные скважины 1 параллельно будущей поверхности отo коса 2. В скважины опускают арматуру/ зар жаю их и взырвают. После взрыва образуютс две зоны: зона 3 дроблени пород и зона 4 раскрыти трещин. Затем бур т вертикальs ные скважины 5, основна часть которых пересекает обе зоны. В скважине 5 нагнетают воду под давлением, обеспечивающим взвешивание и вынос на поверхность породной мелочи из The method is as follows. At the approach of mining to the border of the open pit, inclined wells 1 are drilled parallel to the future surface of the spit 2. In the wells, the reinforcement is lowered / charged and drilled. After the explosion, two zones are formed: the zone 3 for crushing rocks and zone 4 for cracking. Then, vertical wells 5 are drilled, the main part of which intersects both zones. In the well 5, water is injected under pressure, which provides for weighing and carrying to the surface fine rock from
0 зоны 3 и промывку трещин зоны 4. Затем в эти скважины опускают армировочную конструкцию до верхней отметки зоны 3, оборудуют скважины кондукторами и нагнетают цементный раст5 вор э указанные зоны до верхней отметки , зоны 3. Послб извлечени кондук оров верхнюю свободную часть скважин 5 используют дл оформлени уступа . Зар ды в верхней свободной час0 ти скважин 5 взрывают вместе с зар дами в скважинах 6. В результате таких операций образуетс армированHbjift породобетонный слой.0 zone 3 and washing the cracks of zone 4. Then the reinforcement structure is lowered into these wells to the upper mark of zone 3, the wells are equipped with conductors and cement is pumped into the specified zones to the upper mark, zones 3. The upper free part of the wells 5 are used to extract wells for clearance ledge. The charges in the upper free part of the wells 5 explode together with the charges in the wells 6. As a result of such operations, a rock-concrete layer is reinforced with Hbjift.
